Editing a Bash Command

Try typing a long command say, then, type "fc" for an easy way
to edit the command.

$ find /etc -iname '*.cnf' -exec grep -H 'log' {} \;
$ fc

"fc" will bring the last command typed into an editor, "emacs" if
that's the default editor. Type "fc -l" to list last few commands.

To seach for a command, try typing "CTL-r" at the shell prompt for
searching. "CTL-t" to transpose, say "sl" was typed by you want "ls".



Hints when using "fc: in emacs:

ESC-b     move one word backward
ESC-f     move one word forward
ESC-DEL   kill one word backward
CTL-k     kill point to end
CTL-y     un-yank killed region at point
