Trapping $! output
hey all,
I have a script that creates and then distributes html files via scp on a 60 second cycle. On occasions the scp will hang and not complete with the cycle. When running the scp command in the back ground it returns the PID. How do I trap $! in the script? Code:
job=`echo $!` returns an error. -bash-3.00$ job=`echo $!` -bash: !`: event not found What I want to be able to do is monitor how long the scp runs for, if it is still running 2 minutes after starting then it is hung (can't just ps for the scp command as the scp script is used by multiple applications). Any ideas? Cheers, Neil |
