>Organization:
British Broadcasting Corporation
>Environment:
SunOS build0 5.8 Generic_108528-15 sun4u sparc SUNW,UltraSPARC-IIi-cEngine
SunOS build1 5.9 Generic_112233-01 sun4u sparc SUNW,UltraSPARC-IIi-cEngine
>Description:
/usr/xpg4/bin/egrep -q on SunOS doesn't do what it says on the tin.
Fortunately (or not, depending on how you interpret "The
/usr/xpg4/bin/egrep utility is identical to /usr/xpg4/bin/grep -E"), invoking as /usr/xpg4/bin/grep -E works as expected.

$ echo "foo" > testfile

$ /usr/xpg4/bin/egrep -q foo testfile
Usage:  egrep [-c|-l|-q] [-bhinsvx] [file ...]
egrep [-c|-l|-q] [-bhinsvx] -e pattern... [-f pattern_file]...[file...]
egrep [-c|-l|-q] [-bhinsvx] [-e pattern]... -f pattern_file [file...]

$ echo $?
2

$ /usr/xpg4/bin/grep -E -q foo testfile

$ echo $?
0

Confirmed on SunOS 5.7, 5.8, 5.9
>How-To-Repeat:
pkgsrc/mk/bulk/bsd.bulk-pkg.mk uses ${EGREP} -q quite a lot, so can be
verified using that.  Breakage for bulk builds is what pointed out the
bug, and there may be other uses of it within specific packages.
