Print line X from a text file
$ sed 'LINEq;d' FILE
Delete line X in a text file
$ sed -i LINEd FILE
...for example, .ssh/known_hosts:
$ sed -i 672d ~/.ssh/known_hosts
For some reason,
ssh-keygen -R
doesn't always work for me. But the
sed
command does.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
