Depending on your server the error could be that the group doesn't exist i.e. on unix you would need to add the groups to /etc/group first.

Dear All, I have a input file containing all the rolnos of 400 studenst. I have written a small perl script to create their home directories in the cluster server. everything worked fine except for the reason that, it shows up error message indicating that the following messages for example: when my input file rr.txt contains the following roll nos.:- s08-1-5-095 s08-1-5-096 s08-1-5-097 the error messages displayed are :- [EMAIL PROTECTED] perl]# perl h20.pl chgrp: invalid group `s08-1-5-095' chgrp: invalid group `s08-1-5-096' chgrp: invalid group `s08-1-5-097' The ls -l listing shows up the following :- drwx------ 2 s08-1-5-095 root 4096 2008-08-20 17:28 s08-1-5-095 drwx------ 2 s08-1-5-096 root 4096 2008-08-20 17:28 s08-1-5-096 drwx------ 2 s08-1-5-097 root 4096 2008-08-20 17:28 s08-1-5-097 As shown above the group is shown as root, but i want each student to be the group itself, for example it should be : drwx------2 s08-1-5-095 s08-1-5-095 4096 2008-08 17:28 s08-1-5-095 The perl script is shown below: Can anyone tell me what changes should I make in the script so as to make the group same as owner i.e., the roll no. itself. #!/usr/local/bin/perl $file = '/root/perl/rr.txt'; open(PWD, $file); while(<PWD>) { ($a)=split(/\s+/,$_); #system("mkdir /root/perl/$a"); system("chmod 700 /root/perl/$a"); #system("chown /root/perl/$a $a"); system("chgrp $a /root/perl/$a" ); } close(PWD); ~ Thanks, Jyotishmaan Ray Moderator Of Paradise Groups http://yahoogroups.com/group/Spirituality-Paradise Are You Spiritually Aware !!!
