in reply to problem in running UNIX command through perl

Check the status of your command using system, and try getting rid of all those quotes: 
my $cmd = "egrep -f $_proj_file $_running_file > $_admin_temp_file";
print $cmd, "\n";
my $result = system $cmd;
print "result of egrep = $result\n"

    The quotes shouldn't interfere and would be required if he had spaces in his filenames for example

      It sometimes makes the code more readable to delimit strings in qq{}: 
      my $cmd = qq{ egrep -f "$_proj_file" "$_running_file" > "$_admin_temp_
+file" };
my $result = `$cmd`; # or even qx{$cmd}

      That keeps you from having to escape quotes, etc.
