I am trying to parse the master.passwd file during gdm logins to see if
the passwd has reached its expiration time. The following command works
on the command line and in a simple sh script that I tested:
CHANGE=`perl -e "print join(':', getpwnam ('$USER'));" | awk -F: '{print $5}'`
However, it does not work when put into gdm/PreSession/Default.
Here is my PreSession/Default file. I put in an echo command to see the
values.
--begin gdm/PreSession/Default--
#!/bin/sh
#
# Note that any setup should come before the sessreg command as
# that must be 'exec'ed for the pid to be correct (sessreg uses the parent
# pid)
#
# Note that output goes into the .xsession-errors file for easy debugging
#
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
xrdb /etc/X11/Xresources
xmessage -nearmouse -file /etc/motd -default okay
if /usr/bin/which -s xsetroot > /dev/null 2>&1; then
xsetroot -cursor_name left_ptr -solid "#363047"
fi
TIME=`date +%s`
CHANGE=`perl -e "print join(':', getpwnam ('$USER'));" | awk -F: '{print $5}'`
echo TIME is $TIME CHANGE is $CHANGE EXPIRED is $EXPIRED > ~/aging
if [ "$EXPIRED" = "yes" ]; then
xterm -e passwd
fi
if /usr/bin/which -s sessreg > /dev/null 2>&1; then
# some output for easy debugging
echo "$0: Registering your session with wtmp and utmp"
echo "$0: running: sessreg -a -w /var/log/wtmp -u /var/run/utmp -x \"$X_SERVERS\" -h \"$REMOTE_HOST\" -l $DISPLAY $USER"
exec sessreg -a -w /var/log/wtmp -u /var/run/utmp -x "$X_SERVERS" -h "$REMOTE_HOST" -l $DISPLAY $USER
# this is not reached
fi
# some output for easy debugging
echo "$0: could not find the sessreg utility, cannot update wtmp and utmp"
exit 0
--end gdm/PreSession/Default--
Here are the contents of the ~/aging file:
TIME is 1055258058 CHANGE is EXPIRED is
Does any one have any idea why that perl command is not working when run
in the gdm PreSession/Default script?
Thanks.
