vipw - the program

[Joseph E Poplawski]

For those of you who were looking for a copy of 'vipw', here is one that I
wrote.  I want to thank Mike Khaw (mkhaw at teknowledge.arpa) for his suggestions
on what the program should do.

Here it is:

---------------------CUT HERE--------------------------------------------------
# vipw
#
# program to edit the password file. will not allow editing if /etc/ptmp exists.
#
# written by: Jo Poplawski  jep at fantasci.UUCP
#

if [ "n$EDITOR" = "n" ]
then
	EDITOR=/usr/bin/vi
fi

if [ -f "/etc/ptmp" ]
then
	echo ""
	echo "/etc/passwd being used, please try again in a few minutes..."
	echo ""
	exit 1
else
	cat /dev/null >/etc/ptmp
	cp /etc/passwd /etc/ptmp
	$EDITOR /etc/ptmp
	cp /etc/passwd /etc/passwd.old
	mv /etc/ptmp /etc/passwd
	chown root /etc/passwd
	chgrp sys  /etc/passwd
	chmod 444  /etc/passwd
	chmod 000  /etc/passwd.old
fi
