I don't know whether it is right or wrong when I give sudo before that command now its running .. I am new to linux , if I am doing anything wrong, please let me know , as I am working on my institute server system through SSH,
Thank you
It's a permissions problem on the perl script. You shouldn't have to use sudo to run anything besides administration tasks. I'd recommend asking your system administrator to allow execution of this script by a group ID (gid) that you are a part of, else make it executable by all.
