Hi all, i want to run one .pl file in nohup which is configured in crontab. my crontab looks like this: here i am running cron_ncp.pl every minute [root@perflnx14 SCRIPTS]# crontab -l * * * * * perl /root/nfs_share/SCRIPTS/cron_ncp.pl >>/root/nfs_share/SCRIPTS/temp.txt ---------------- cron_tab.pl script contails: #!/usr/bin/perl use warnings; use strict; my $cmd='nohup expect -f /root/nfs_share/SCRIPTS/ncp_run.tcl &'; my $tmp= `ps -ef | grep -v grep | grep ncp_run.tcl | wc -l`; if($tmp == 1) { print"already running\n"; } else { print"not running\n"; system $cmd; } here as you can see if ncp_run.tcl is not running than it will kick start the ncp_run.tcl in nohup __________ but this is not happening , everything is working fine it in the above script i replace $cmd with just another command like date..problem i am facing when i want to start the ncp_run.tcl in nohup
