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/S
+CRIPTS/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
