This & That

Refer to 'that last thing', and 'the first thing':

fortune -l > file1
cat !$  | tr -d u
diff !^ !$

NB: this can go wrong:

ls -l file1 file2
cat !^

NB: this only works when running bash interactively, never in scripts.

Done

<C-d>

• If you have a command, Control + d will execute the command.
• If you have nothing, exit.

Search & Clear Highlights

You can search in many programs by using /. Most programs let you clearn the highlighting with <Esc>+u.
