I have a file with which i must remove the last line of the file (the footer). I know how to copy and redirect with tail -1 etc, but how do i delete it permanentely

With sed you can do the following:

$ sed '$d' original_file > file_without_last_line

Then you still have the original one if you need it.
In the file_without_last_line you have the desired result.

To update the file in place, you could use the ex editor.

ex - file1 << EOF
$d
wq
EOF

Hope this helps. CaKiwi
