Top Forums Shell Programming and Scripting how can I delete lines without actually going into the file Post 17185 by LivinFree on Tuesday 12th of March 2002 02:56:06 AM

What about using "ed", or "ex"?
Say, you had a list of files and directories in a text file named tmp.list.
If you wanted to get rid of all items matching "Desktop" (the same as using "grep -v Desktop tmp.list > file.tmp; mv file.tmp tmp.list), you could do this:
Code:
ed tmp.list <<EndOfFile
g/Desktop/d
w
q
EndOfFile

... Piece of cake, eh?
