in reply to system command with here-doc

I agree with JavaFan. It's not really a Perl question, but the sg command will do essentially the same thing without starting another shell.

    I get really confused with the setgid and setuid. I need it for this one system command. The linking/checkin can only be done under that group. The below code works.

    ## system ("newgrp ankoor <<BLAH\n cleartool setview -exec \"cleartool ln + -s $rtl_compiles_dir/$new_release $topsim_dir/SIMULIBS/vcsmx/$new_re +lease\" $view_name \nBLAH\n 2>>$0.ERR") if (!$flag_link); ##

    Yes the BLAH should come at the end theoretically, but that somehow causes issues, along with the redirecting error. The linking which I am trying to do works out fine but I get some garbage along with that which I am trying to redirect it to a log, and not on the stdout which will make it look messy. Here's the system command output I get.

    ## stty: standard input: Inappropriate ioctl for device Link created: "/cdb/topsimaegis//SIMULIBS/vcsmx/LINK_DIR". BLAH: Command not found. 2: Command not found. ##

    As you see the redirecting also fails along with the label ending which goes unrecognized.

      Can anyone help me on this

        Help with what, debugging a shell script?
