I think perhaps an explanation that the file extension in linux generally does not affect what the OS will do with the file. In gui window managers, the extension is sometimes used to work out which application to open it with, but when it comes to command line usage, in particular executable scripts, the extension is purely a hint for users. If a file has the executable bit, then the OS will try and run it when asked. If it is a text file, then it looks a the first line. If the first line is #!/bin/bash (usually referred to as she-bang /bin/bash) then when you run "./script" the OS will ask /bin/bash to run the contents of the file, even if the file has an extension that might suggest something else Anton -- Anton Piatek email: an...@piatek.co.uk blog/photos: http://www.strangeparty.com pgp: [74B1FA37] (http://www.strangeparty.com/anton.asc) fingerprint: 7401 96D3 E037 2F8F 5965 A358 4046 71FD 74B1 FA37 No trees were destroyed in the sending of this message, however, a significant number of electrons were terribly inconvenienced. -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --------------------------------------------------------------
