>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 one :)
This contains a shar of line(1). It reads in one line of text
up to and including a new line and prints it to the standard output.
It has been depreciated in Unix 98 and will probably be removed in
the next edition of the standard.
>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
# line.1
# line.c
#
echo x - Makefile
sed 's/^X//' >Makefile << 'END-of-Makefile'
XPROG=line
X
X.include <bsd.prog.mk>END-of-Makefile
echo x - line.1
sed 's/^X//' >line.1 << 'END-of-line.1'
