+.Dt FIND 1
+.Os
+.Sh NAME
+.Nm find
+.Nd walk a file hierarchy
+.Sh SYNOPSIS
+.Nm find
+.Op Fl H | Fl L | Fl P
+.Op Fl Xdx
+.Op Fl f Ar file
+.Op Ar file ...
+.Ar expression
+.Sh DESCRIPTION
+.Nm Find
+recursively descends the directory tree for each
+.Ar file
+listed, evaluating an
+.Ar expression
+(composed of the ``primaries'' and ``operands'' listed below) in terms
+of each file in the tree.
+.Pp
+The options are as follows:
+.Pp
+.Bl -tag -width Ds
+.It Fl H
+The
+.Fl H
+option causes the file information and file type (see
+.Xr stat 2)
+returned for each symbolic link specified on the command line to be 
+those of the file referenced by the link, not the link itself.
+If the referenced file does not exist, the file information and type will
+be for the link itself.  File information of all symbolic links not on 
+the command line is that of the link itself.
+.It Fl L
+The
+.Fl L
+option causes the file information and file type (see
+.Xr stat 2)
+returned for each symbolic link to be those of the file referenced by the
+link, not the link itself.
+If the referenced file does not exist, the file information and type will
+be for the link itself.
+.It Fl P
+The
+.Fl P
+option causes the file information and file type (see
+.Xr stat 2)
+returned for each symbolic link to be those of the link itself.
+.It Fl X
+The
+.Fl X
+option is a modification to permit
+.Nm
+to be safely used in conjunction with
+.Xr xargs 1 .
+If a file name contains any of the delimiting characters used by
+.Xr xargs ,
+a diagnostic message is displayed on standard error, and the file
+is skipped.
+The delimiting characters include single (`` ' '') and double (`` " '')
+quotes, backslash (``\e''), space, tab and newline characters.
+.It Fl d
+The
+.Fl d
+option causes
+.Nm find
+to perform a depth\-first traversal, i.e. directories
+are visited in post\-order and all entries in a directory will be acted
+on before the directory itself.
+By default,
+.Nm find
+visits directories in pre\-order, i.e. before their contents.
+Note, the default is
+.Ar not
+a breadth\-first traversal.
+.It Fl f
+The
+.Fl f
+option specifies a file hierarchy for
+.Nm find
+to traverse.
+File hierarchies may also be specified as the operands immediately
+following the options.
+.It Fl x
+The
+.Fl x
+option prevents
+.Nm find
+from descending into directories that have a device number different
+than that of the file from which the descent began.
+.El
+.Sh PRIMARIES
+.Bl -tag -width Ds
+.It Ic -atime Ar n 
+True if the difference between the file last access time and the time
+.Nm find
+was started, rounded up to the next full 24\-hour period, is
+.Ar n
+24\-hour periods.
+.It Ic -ctime Ar n 
+True if the difference between the time of last change of file status
+information and the time
+.Nm find
+was started, rounded up to the next full 24\-hour period, is
+.Ar n
+24\-hour periods.
+.It Ic -exec Ar utility Op argument ... ; 
+True if the program named
+.Ar utility
+returns a zero value as its exit status.
+Optional arguments may be passed to the utility.
+The expression must be terminated by a semicolon (``;'').
+If the string ``{}'' appears anywhere in the utility name or the
+arguments it is replaced by the pathname of the current file.
+.Ar Utility
+will be executed from the directory from which
+.Nm find
+was executed.
+.It Ic -fstype Ar type 
+True if the file is contained in a file system of type
+.Ar type .
+The
+.Xr sysctl 8
+command can be used to find out the types of filesystems
+that are available on the system:
+.Bd -literal -offset indent
+sysctl vfs
+.Ed
+In addition, there are two pseudo-types, ``local'' and ``rdonly''.
+The former matches any file system physically mounted on the system where
+the
+.Nm find
+is being executed and the latter matches any file system which is
+mounted read-only.
+.It Ic -group Ar gname 
+True if the file belongs to the group
+.Ar gname  .
+If
+.Ar gname
+is numeric and there is no such group name, then
+.Ar gname
+is treated as a group id.
+.It Ic -inum Ar n 
+True if the file has inode number
+.Ar n  .
+.It Ic -links Ar n 
+True if the file has
+.Ar n
+links.
+.It Ic -ls
+This primary always evaluates to true.
+The following information for the current file is written to standard output:
+its inode number, size in 512\-byte blocks, file permissions, number of hard
+links, owner, group, size in bytes, last modification time, and pathname.
+If the file is a block or character special file, the major and minor numbers
+will be displayed instead of the size in bytes.
+If the file is a symbolic link, the pathname of the linked\-to file will be
+displayed preceded by ``\->''.
+The format is identical to that produced by ``ls \-dgils''.
+.It Ic -mtime Ar n 
+True if the difference between the file last modification time and the time
+.Nm find
+was started, rounded up to the next full 24\-hour period, is
+.Ar n
+24\-hour periods.
+.It Ic \&-ok Ar utility Op argument ... ; 
+The
+.Ic \&-ok
+primary is identical to the
+.Ic -exec
+primary with the exception that
+.Nm find
+requests user affirmation for the execution of the utility by printing
+a message to the terminal and reading a response.
+If the response is other than ``y'' the command is not executed and the
+value of the
+.Ar \&ok
+expression is false.
+.It Ic -name Ar pattern 
+True if the last component of the pathname being examined matches
+.Ar pattern  .
+Special shell pattern matching characters (``['', ``]'', ``*'', and ``?'')
+may be used as part of
+.Ar pattern  .
+These characters may be matched explicitly by escaping them with a
+backslash (``\e'').
+.It Ic -newer Ar file 
+True if the current file has a more recent last modification time than
+.Ar file  .
+.It Ic -nouser
+True if the file belongs to an unknown user.
+.It Ic -nogroup
+True if the file belongs to an unknown group.
+.It Ic -path Ar pattern 
+True if the pathname being examined matches
+.Ar pattern  .
+Special shell pattern matching characters (``['', ``]'', ``*'', and ``?'')
+may be used as part of
+.Ar pattern  .
+These characters may be matched explicitly by escaping them with a
+backslash (``\e'').
+Slashes (``/'') are treated as normal characters and do not have to be
+matched explicitly.
+.It Ic -perm Op Fl Ns Ar mode 
+The
+.Ar mode
+may be either symbolic (see
+.Xr chmod  1  )
+or an octal number.
+If the mode is symbolic, a starting value of zero is assumed and the
+mode sets or clears permissions without regard to the process' file mode
+creation mask.
+If the mode is octal, only bits 07777
+.Pf ( Dv S_ISUID
+|
+.Dv S_ISGID
+|
+.Dv S_ISTXT
+|
+.Dv S_IRWXU
+|
+.Dv S_IRWXG
+|
+.Dv S_IRWXO )
+of the file's mode bits participate
+in the comparison.
+If the mode is preceded by a dash (``\-''), this primary evaluates to true
+if at least all of the bits in the mode are set in the file's mode bits.
+If the mode is not preceded by a dash, this primary evaluates to true if
+the bits in the mode exactly match the file's mode bits.
+Note, the first character of a symbolic mode may not be a dash (``\-'').
+.It Ic -print
+This primary always evaluates to true.
+It prints the pathname of the current file to standard output.
+If none of
+.Ic -exec ,
+.Ic -ls ,
+or
+.Ic \&-ok
+is specified, the given expression shall be effectively replaced by
+.Cm \&( Ns Ar given\& expression Ns Cm \&) 
+.Ic -print .
+.It Ic -prune
+This primary always evaluates to true.
+It causes
+.Nm find
+to not descend into the current file.
+Note, the
+.Ic -prune
+primary has no effect if the
+.Fl d
+option was specified.
+.It Ic -size Ar n Ns Op Cm c 
+True if the file's size, rounded up, in 512\-byte blocks is
+.Ar n  .
+If
+.Ar n
+is followed by a ``c'', then the primary is true if the
+file's size is
+.Ar n
+bytes.
+.It Ic -type Ar t 
+True if the file is of the specified type.
+Possible file types are as follows:
+.Pp
+.Bl -tag -width flag -offset indent -compact
+.It Cm b
+block special
+.It Cm c
+character special
+.It Cm d
+directory
+.It Cm f
+regular file
+.It Cm l
+symbolic link
+.It Cm p
+FIFO
+.It Cm s
+socket
+.El
+.Pp
+.It Ic -user Ar uname 
+True if the file belongs to the user
+.Ar uname  .
+If
+.Ar uname
+is numeric and there is no such user name, then
+.Ar uname
+is treated as a user id.
+.El
+.Pp
+All primaries which take a numeric argument allow the number to be
+preceded by a plus sign (``+'') or a minus sign (``\-'').
+A preceding plus sign means ``more than n'', a preceding minus sign means
+``less than n'' and neither means ``exactly n'' .
+.Sh OPERATORS
+The primaries may be combined using the following operators.
+The operators are listed in order of decreasing precedence.
+.Bl -tag -width (expression) 
+.It Cm \&( Ns Ar expression Ns Cm \&) 
+This evaluates to true if the parenthesized expression evaluates to
+true.
+.Pp
+.It Cm \&! Ns Ar expression 
+This is the unary
+.Tn NOT
+operator.
+It evaluates to true if the expression is false.
+.Pp
+.It Ar expression Cm -and Ar expression 
+.It Ar expression expression 
+The
+.Cm -and
+operator is the logical
+.Tn AND
+operator.
+As it is implied by the juxtaposition of two expressions it does not
+have to be specified.
+The expression evaluates to true if both expressions are true.
+The second expression is not evaluated if the first expression is false.
+.Pp
+.It Ar expression Cm -or Ar expression 
+The
+.Cm -or
+operator is the logical
+.Tn OR
+operator.
+The expression evaluates to true if either the first or the second expression
+is true.
+The second expression is not evaluated if the first expression is true.
+.El
+.Pp
+All operands and primaries must be separate arguments to
+.Nm find  .
+Primaries which themselves take arguments expect each argument
+to be a separate argument to
+.Nm find  .
+.Sh EXAMPLES
+.Pp
+The following examples are shown as given to the shell:
+.Bl -tag -width findx
+.It Li "find  /  \e!  -name  \*q*.c\*q  -print"
+Print out a list of all the files whose names do not end in ``.c''.
+.It Li "find  /  -newer  ttt  -user  wnj  -print"
+Print out a list of all the files owned by user ``wnj'' that are newer
+than the file ``ttt''.
+.It Li "find  /  \e!  \e(  -newer  ttt  -user  wnj  \e)  -print"
+Print out a list of all the files which are not both newer than ``ttt''
+and owned by ``wnj''.
+.It Li "find  /  \e(  -newer  ttt  -or  -user wnj  \e)  -print"
+Print out a list of all the files that are either owned by ``wnj'' or
+that are newer than ``ttt''.

+.Sh STANDARDS
+The
+.Nm find
+utility syntax is a superset of the syntax specified by the
+.St -p1003.2
+standard.
+.Pp
+The
+.Fl s
+and
+.Fl X
+options and the
+.Ic -inum
+and
+.Ic -ls
+primaries are extensions to
+.St -p1003.2 .
+.Pp
+Historically, the
+.Fl d ,
+.Fl h
+and
+.Fl x
+options were implemented using the primaries ``\-depth'', ``\-follow'',
+and ``\-xdev''.
+These primaries always evaluated to true.
+As they were really global variables that took effect before the traversal
+began, some legal expressions could have unexpected results.
+An example is the expression ``\-print \-o \-depth''.
+As \-print always evaluates to true, the standard order of evaluation
+implies that \-depth would never be evaluated.
+This is not the case.
+.Pp
+The operator ``-or'' was implemented as ``\-o'', and the operator ``-and''
+was implemented as ``\-a''.
+.Pp
+Historic implementations of the
+.Ic exec
+and
+.Ic ok
+primaries did not replace the string ``{}'' in the utility name or the
+utility arguments if it had preceding or following non-whitespace characters.
+This version replaces it no matter where in the utility name or arguments
+it appears.
+.Sh BUGS
+The special characters used by
+.Nm find
+are also special characters to many shell programs.
+In particular, the characters ``*'', ``['', ``]'', ``?'', ``('', ``)'',
+``!'', ``\e'' and ``;'' may have to be escaped from the shell.
+.Pp
+As there is no delimiter separating options and file names or file
+names and the
+.Ar expression ,
+it is difficult to specify files named ``-xdev'' or ``!''.
+These problems are handled by the
+.Fl f
+option and the
+.Xr getopt 3
+``--'' construct.

+.Sh NAME
+.Nm finger
+.Nd user information lookup program
+.Sh SYNOPSIS
+.Nm finger
+.Op Fl lmsp
+.Op Ar user ...
+.Op Ar user@host ...
+.Sh DESCRIPTION
+The
+.Nm finger
+displays information about the system users.
+.Pp
+Options are:
+.Bl -tag -width flag
+.It Fl s
+.Nm Finger
+displays the user's login name, real name, terminal name and write
+status (as a ``*'' before the terminal name if write permission is
+denied), idle time, login time, office location and office phone
+number.
+.Pp
+Idle time is in minutes if it is a single integer, hours and minutes
+if a ``:'' is present, or days if a ``d'' is present.
+Login time is displayed as month, day, hours and minutes, unless
+more than six months ago, in which case the year is displayed rather
+than the hours and minutes.
+.Pp
+Unknown devices as well as nonexistent idle and login times are
+displayed as single asterisks.
+.Pp
+.It Fl l
+Produces a multi-line format displaying all of the information
+described for the
+.Fl s
+option as well as the user's home directory, home phone number, login
+shell, and the contents of the files
+.Dq Pa .forward ,
+.Dq Pa .plan
+and
+.Dq Pa .project
+from the user's home directory.
+.Pp
+If idle time is at least a minute and less than a day, it is
+presented in the form ``hh:mm''.
+Idle times greater than a day are presented as ``d day[s]hh:mm''.
+.Pp
+Phone numbers specified as eleven digits are printed as ``+N-NNN-NNN-NNNN''.
+Numbers specified as ten or seven digits are printed as the appropriate
+subset of that string.
+Numbers specified as five digits are printed as ``xN-NNNN''.
+.Pp
+If write permission is denied to the device, the phrase ``(messages off)''
+is appended to the line containing the device name.
+One entry per user is displayed with the
+.Fl l
+option; if a user is logged on multiple times, terminal information
+is repeated once per login.
+.Pp
+.It Fl p
+Prevents
+the
+.Fl l
+option of
+.Nm finger
+from displaying the contents of the
+.Dq Pa .forward ,
+.Dq Pa .plan
+and
+.Dq Pa .project
+files.
+.It Fl m
+Prevent matching of
+.Ar user
+names.
+.Ar User
+is usually a login name; however, matching will also be done on the
+users' real names, unless the
+.Fl m
+option is supplied.
+All name matching performed by
+.Nm finger
+is case insensitive.
+.El
+.Pp
+If no options are specified,
+.Nm finger
+defaults to the
+.Fl l
+style output if operands are provided, otherwise to the
+.Fl s
+style.
+Note that some fields may be missing, in either format, if information
+is not available for them.
+.Pp
+If no arguments are specified,
+.Nm finger
+will print an entry for each user currently logged into the system.
+.Pp
+.Nm Finger
+may be used to look up users on a remote machine.
+The format is to specify a
+.Ar user
+as
+.Dq Li user@host ,
+or
+.Dq Li @host ,
+where the default output
+format for the former is the
+.Fl l
+style, and the default output format for the latter is the
+.Fl s
+style.
+The
+.Fl l
+option is the only option that may be passed to a remote machine.

+.Sh NAME
+.Nm join
+.Nd relational database operator
+.Sh SYNOPSIS
+.Nm join
+.Oo
+.Fl a Ar file_number | Fl v Ar file_number
+.Oc
+.Op Fl e Ar string
+.Op Fl j Ar file_number field
+.Op Fl o Ar list
+.Bk -words
+.Ek
+.Op Fl t Ar char
+.Op Fl \&1 Ar field
+.Op Fl \&2 Ar field
+.Ar file1
+.Ar file2
+.Sh DESCRIPTION
+The join utility performs an ``equality join'' on the specified files
+and writes the result to the standard output.
+The ``join field'' is the field in each file by which the files are compared.
+The first field in each line is used by default.
+There is one line in the output for each pair of lines in
+.Ar file1
+and
+.Ar file2
+which have identical join fields.
+Each output line consists of the join field, the remaining fields from
+.Ar file1
+and then the remaining fields from
+.Ar file2 .
+.Pp
+The default field separators are tab and space characters.
+In this case, multiple tabs and spaces count as a single field separator,
+and leading tabs and spaces are ignored.
+The default output field separator is a single space character.
+.Pp
+Many of the options use file and field numbers.
+Both file numbers and field numbers are 1 based, i.e. the first file on
+the command line is file number 1 and the first field is field number 1.
+The following options are available:
+.Bl -tag -width Fl
+.It Fl a Ar file_number
+In addition to the default output, produce a line for each unpairable
+line in file
+.Ar file_number .
+(The argument to
+.Fl a
+must not be preceded by a space; see the
+.Sx COMPATIBILITY
+section.)
+.It Fl e Ar string
+Replace empty output fields with
+.Ar string .
+.It Fl o Ar list
+The
+.Fl o
+option specifies the fields that will be output from each file for
+each line with matching join fields.
+Each element of
+.Ar list
+has the form
+.Ql file_number.field ,
+where
+.Ar file_number
+is a file number and
+.Ar field
+is a field number.
+The elements of list must be either comma (``,'') or whitespace separated.
+(The latter requires quoting to protect it from the shell, or, a simpler
+approach is to use multiple
+.Fl o
+options.)
+.It Fl t Ar char
+Use character
+.Ar char
+as a field delimiter for both input and output.
+Every occurrence of
+.Ar char
+in a line is significant.
+.It Fl v Ar file_number
+Do not display the default output, but display a line for each unpairable
+line in file
+.Ar file_number .
+The options
+.Fl v Ar 1
+and
+.Fl v Ar 2
+may be specified at the same time.
+.It Fl 1 Ar field
+Join on the
+.Ar field Ns 'th
+field of file 1.
+.It Fl 2 Ar field
+Join on the
+.Ar field Ns 'th
+field of file 2.
+.El
+.Pp
+When the default field delimiter characters are used, the files to be joined
+should be ordered in the collating sequence of
+.Xr sort 1 ,
+using the
+.Fl b
+option, on the fields on which they are to be joined, otherwise
+.Nm join
+may not report all field matches.
+When the field delimiter characters are specified by the
+.Fl t
+option, the collating sequence should be the same as
+.Xr sort
+without the
+.Fl b
+option.
+.Pp
+If one of the arguments
+.Ar file1
+or
+.Ar file2
+is ``-'', the standard input is used.
+.Pp
+The
+.Nm join
+utility exits 0 on success, and >0 if an error occurs.
+.Sh COMPATIBILITY
+For compatibility with historic versions of
+.Nm join ,
+the following options are available:
+.Bl -tag -width Fl
+.It Fl a
+In addition to the default output, produce a line for each unpairable line
+in both file 1 and file 2.
+(To distinguish between this and
+.Fl a Ar file_number ,
+.Nm join
+currently requires that the latter not include any white space.)
+.It Fl j1 Ar field
+Join on the
+.Ar field Ns 'th
+field of file 1.
+.It Fl j2 Ar field
+Join on the
+.Ar field Ns 'th
+field of file 2.
+.It Fl j Ar field
+Join on the
+.Ar field Ns 'th
+field of both file 1 and file 2.
+.It Fl o Ar list ...
+Historical implementations of
+.Nm join
+permitted multiple arguments to the
+.Fl o
+option.
+These arguments were of the form ``file_number.field_number'' as described
+for the current
+.Fl o
+option.
+This has obvious difficulties in the presence of files named ``1.2''.
+.El
+.Pp
+These options are available only so historic shellscripts don't require
+modification and should not be used.
+.Sh STANDARDS
+The
+.Nm join
+command is expected to be
+.St -p1003.2
+compatible.
+.Sh SEE ALSO
