The exact output format depends on the locale. If a command-line argument starts with a plus sign ("+"), the rest of - the argument is used as a format that controls what appears in the - output. In the format, when a percent sign ("%" appears, it and the - character after it are not output, but rather identify part of the date - or time to be output in a particular way (or identify a special - character to output): - - Sample output Explanation - %a Wed Abbreviated weekday name* - %A Wednesday Full weekday name* - %b Mar Abbreviated month name* - %B March Full month name* - %c Wed Mar 08 14:54:40 1989 Date and time* - %C 19 Century - %d 08 Day of month (always two digits) - %D 03/08/89 Month/day/year (eight characters) - %e 8 Day of month (leading zero blanked) - %h Mar Abbreviated month name* - %H 14 24-hour-clock hour (two digits) - %I 02 12-hour-clock hour (two digits) - %j 067 Julian day number (three digits) - %k 2 12-hour-clock hour (leading zero blanked) - %l 14 24-hour-clock hour (leading zero blanked) - %m 03 Month number (two digits) - %M 54 Minute (two digits) - %n \n newline character - %p PM AM/PM designation - %r 02:54:40 PM Hour:minute:second AM/PM designation - %R 14:54 Hour:minute - %S 40 Second (two digits) - %t \t tab character - %T 14:54:40 Hour:minute:second - %U 10 Sunday-based week number (two digits) - %w 3 Day number (one digit, Sunday is 0) - %W 10 Monday-based week number (two digits) - %x 03/08/89 Date* - %X 14:54:40 Time* - %y 89 Last two digits of year - %Y 1989 Year in full - %z -0500 Numeric time zone - %Z EST Time zone abbreviation - %+ Wed Mar 8 14:54:40 EST 1989 Default output format* - * The exact output depends on the locale. - - If a character other than one of those shown above appears after a - percent sign in the format, that following character is output.
