Here's a sample script that checks for an adsl pid and does something
when the "ps auxww" command doesn't produce a line with "adsl" in it:
----------------------------------------------------------------------------
#!/bin/bash
PID=`ps auxww | grep adsl | grep -v grep | awk '{print $2}'`
if [ -z "$PID" ]; then
echo No adsl pid found. Run adsl-connect.
fi
-----------------------------------------------------------------------------
If the script, as modified by you, is, say, /usr/local/bin/checkadsl, it
will run every 5 minutes with the following line in root's crontab:
*/5 * * * * /usr/local/bin/checkadsl
For more information, do "man -a crontab".
