Files get messed up with multiple lines containing
bar. I want to remove all of them and append one line of each at the end.
So, given a file
some stuff foo1 foo2 bar=42 some other stuff bar foo more stuff
the sed script should return
some stuff some other stuff more stuff foo bar
I tried with sed
'/foo/d;/bar/d;$s/$/\nfoo\nbar/' which works as long as the last line contains neither
bar and the file is not empty.
How to do make it work even with
foo in the last line? I'd like to stick to sed, becuase the whole script should do more than just this. Of source I could append my lines with echo after the script, but I wonder if there is no all-in-one-solution.
Edit: The empty file case doesn't need to be handled.
