[bash] remove lines from a file
I am trying to write a script to generate a menu for XFce4 on the fly when I login.
My goal is to generate a menu using Menu Maker and append that to a base menu I have created. The problem with appending is that the automatically generated file, menuAuto.xml, has tags that prevent the resulting menu file from being a valid menu.
I figure that if I wrote some script to remove the first 3 lines from menuAuto.xml, the append will work correctly.
What code is necessary for a bash script to remove the first 3 lines from a file?
Thanks in advance! I think this will be a neat little script once it is finished.
