FreeBSD byzantine 3.2-STABLE FreeBSD 3.2-STABLE #5: Sat Aug 7 23:43:54 GMT 1999 root@byzantine:/usr/src/sys/compile/BYZANTINE i386
>Description:
After opening my big mouth on freebsd-advocacy about how Unix 98
compliance was a worthy goal, more than one person told me to go
ahead and send in PRs with changes. Well, here is yet another :)
This contains a shar of unlink(1). unlink accepts one argument and
runs unlink(2) on it thus removing the object listed. NetBSD places
this in /usr/sbin and puts the man page in section 8, but nothing
in the standard dictates where it should be. I have the man page
in section 1. If this is inappropriate, it can be changed without
pain. This implementation contains no NetBSD code.
>How-To-Repeat:
Irrelevant.
>Fix:
# This is a shell archive. Save it in a file, remove anything before
# this line, and then unpack it by entering "sh file". Note, it may
# create directories; files and directories will be owned by you and
# have default permissions.
#
# This archive contains:
#
# Makefile
# unlink.1
# unlink.c
#
echo x - Makefile
sed 's/^X//' >Makefile << 'END-of-Makefile'
XPROG= unlink
X
X.include <bsd.prog.mk>
END-of-Makefile
echo x - unlink.1
sed 's/^X//' >unlink.1 << 'END-of-unlink.1'
