If you have created an alias of a comand with the same name as the command (example: alias ls='ls -al'), you can bypass the alias with a prefixed backslash (example: \ls), which runs the command in its default state.
------------------------
Type a "cd newdirectory; command" command in parentheses to bounce you back to your previous PWD after the command has run:
| Code Sample | $ cd
$ pwd
/home/dsl
$ (cd downloads/Fluxbox/styles; mkdir newstyles)
$ pwd
/home/dsl |
This isn't particularly efficient in many situations, but it works.
------------------------
Brace expansion can save a lot of typing (and bytes in a script).
This means using curly braces to list several unique parts of an otherwise identical command so you don't need to do a lot of retyping.
A couple of examples. First line is the standard command, and the second is the same using brace expansion:
| Code Sample | cp filename.one filename.two
cp filename.{one,two} |
| Code Sample | echo "foo foobar"
echo foo{,bar} |
------------------------
reverse-i-search allows you to use auto-completion to cue up past commands. If you have a command you used way back you don't want to bother using the up key to retrieve it. Instead press Ctrl+r and then type a couple of characters. Bash will search through its history and present you with a command including that string.
------------------------
The CDPATH variable can be utilized much like PATH and LD_LIBRARY_PATH. Set up a CDPATH variable something like this:
export CDPATH=/usr/X11R6/lib:/path/to/something/else
Then do "cd fonts" and you should be taken to /usr/X11R6/lib/fonts
