[gentoo-user] How to tell Cron X is running or not

2007-11-25 Thread reader 
Scripts that test for X running might work in a shell but not when the
script is run by cron.

For example:  This code:
  tty|grep pts
  retval=$?
  if [[ $retval  0 ]];then
print X isn't running just now... postponing rsync of WWW
until such time as it is... exiting
exit
  fi

Runs fine when run from a user shell, but when cron runs it the test
always fails to be true.

So how can I test for X running in case where script will be run by cron?

How about something like this:  retval=`ps aux | grep tty | grep X | awk
'{print $2}'`

Or retval=`cat /tmp/.X0-lock`

Or even better:

if [[ -e /tmp/.X0-lock ]];then
...
