to re-establishment of 64bit arithmetic, but is committed separately, to
not obscure that conversion. This commit does not change the observed
behaviour of expr in any way. Style will be fixed in a follow-up commit.
Make /bin/expr support 64bit numeric range and range checks by default,2011-07-09T12:05:53ZStefan Eßerse@FreeBSD.org2011-07-09T12:05:53Zurn:sha1:fa717604a42dff3416a3e299da0abf01d9f8521e
again. This brings back the behaviour of expr in FreeBSD-4, which had been
reverted due to an assumed incompatbility with POSIX.1 for FreeBSD-5.
This issue has been discussed in the freebsd-standards list, and the
consensus was, that POSIX.1 is in fact not violated by this extension,
since it affects only cases of POSIX undefined behaviour (overflow of
signed long).
Other operating systems did upgrade their versions of expr to support
64bit range, after it had been initially brought to FreeBSD. They have
used it for a decade without problems, meanwhile.
The -e option is retained, but it will only select less strict checking
of numeric parameters (leading white-space, leading "+" are allowed and
skipped, an empty string is considered to represent 0 in numeric context.)
The call of check_utility_compat() as a means of establishing backwards
compatibility with FreeBSD-4 is considered obsolete, but preserved in
this commit. It is expected to be removed in a later revision of this
file.

expr(1): Add sh(1) versions of examples, remove an incorrect example.2010-09-09T21:59:53ZJilles Tjoelkerjilles@FreeBSD.org2010-09-09T21:59:53Zurn:sha1:f390d8d927e2bc6a8afd086bfdcdbf5edcbc6875
The three examples are better done using sh(1) itself these days.
The example
expr -- "$a" : ".*"
is incorrect in the general case, as "$a" may be an operator.
