Sometimes I realize that my latest changes actually should belong to another branch than the one I’m currently working on. The easy way to add the changes to a new branch is to use the stash command.

[… changes …]
git stash
git stash branch name_of_new_branch
git commit […]
git push origin name_of_new_branch

Ref. git stash.

It’s very useful to be able to exclude certain files or directories when using tar. Here’s how I did in Leopard:

tar czvf FILENAME.tgz --exclude={.svn,wiki*,static} FILES_OR_DIRS_TO_TAR

Here’s how I set up SSHKeychain on my Mac:

1. Modify the package content as described
   
2. Add stuff to .bashrc/.profile
3. Add keys to SSHKeychain: Preferences > SSH Keys
4. Check Manage (and modify) global environment variables (this probably has no effect, ref 2.)

I just learned how to open a Finder window directly from the command line.

open .

Yes, it’s actually that easy, and the open command is quite handy some times. This is from the open man page.

The open command opens a file (or a directory or URL), just as if you had double-clicked the
file’s icon. If no application name is specified, the default application as determined via
LaunchServices is used to open the specified files.

This means that you can actually open anything from the command line with the open command. Go ahead and try it out!

Here are the colors available for use in the bash shell prompt:

This is my shell prompt:

PS1='\[\033[01;32m\]\u@\h \[\033[01;35m\]\W \$ \[\033[00m\]'

Which produces output on the form user@computer DIRECTORY $. I use different colors for different computers/users.

find is an extremely powerful command. In order to leave the directory matching *DIRECTORY* out from your search for .txt-files:

find . -path '*DIRECTORY*' -prune -o -iname '*.txt' -print

If you’re using xargs together with find and xargs complains about file names with spaces, use:

find . YOURFINDOPTIONSHERE -print0 | xargs -0 rm -rf

Finding files larger than a certain limit:

find . -size +200M -print0 | xargs -0 ls -lh

Deleting the complementary files:

find . ! -name "*.mp3" -delete

Please note that these commands pertains to the BSD find as on Mac OS 10.5.

UPDATE 20080517: Looking for file size
UPDATE 20080602: Added deleting complement

By adding option -H to the grep command, the filename will be output together with the matching line:

grep -i -H TEXT_TO_SEARCH_FOR

-i turns on ignore case.
