Using History Interactively

Stick the job in the background (ctrl-Z then "bg") then detach it from the terminal (in bash, "disown -h %[jobid]"). You may then close the terminal.


Add to ~/.bashrc:

# Use bash-completion, if available
if [ -f /etc/bash_completion ]; then
  . /etc/bash_completion


M-{} Include all expansions. Also can do things like mkdir -p foo/{cur,new,tmp}.


bind -P will show keybindings.
