# this scriptie removes last line from all scrollback files that

# it creates a backup of your logs to <filename>.poison prior to cleaning the original file
# Don't post this file content or parts of it on any IRC channel, as that will
# earn you a permanent immediate ban on the whole network!

# since I wrote the whole thing as a busybox compatible oneliner, you also could
# just c&p the one line below to your xterm and execute it there, rather than
# downloading, storing on N900 ~user/, setting chmod +x, and then executing the file
