Thanks Edward, I put #!perl -w as the first line, it didn't work,
I made sure that I has the right perl in my path, by running: $which perl I didn't also get the point for the use of ':' in the first line of the script instead of using the #! construct.

Yup. Put the directory where perl resides in your PATH, and use #!perl -w as your perl script header. It will use the first instance of perl in your PATH, so if you have multiple versions installed, make sure that the one you want to use is first (before all other perls) in your path. As far as ':', it depends on the shell, and where it is applied. It can be used as a separator in multiple commands on a single line in 'sh'. I can also be used as a separator in a PATH list. Other shells may use it for other things. It is used in 'csh' as an entity terminator in a switch clause, for example. ego Edward G. Orton, GWN Consultants Inc.
