After typing cd directory [enter] ls [enter] so many times, I figured I'd try to make it into a function. I was surprised how smoothly I was able to integrate it into my work on the command line.

Just use cdls as you would cd. It will automatically list the directory contents after you cd into the directory. To make the command always available, add it to your .bashrc file.

Not quite monumental, but still pretty convenient.

Jan Nelson from Grockit came up with this for us when we needed to rename all of our fixtures.

Removes all unversioned files and folders from an svn repository. Also:

will remove those files which svn status ignores. Handy to add to a script which is in your path so you can run it from any repository (a la 'svn_clean.sh').

What this does is, if I type ?ssh ? then hit the page-up key, it will complete the line to the last time in my history file that I typed ssh. Hitting page up again will go to the 2nd to last time I typed it. Incredibly handy if you ever type the same commands more than once.

This will change all files ending in .JPG to .jpg and will work with any file extension

The SSH server configuration requires:

X11Forwarding yes # this is default in Debian

And it's convenient too:

Compression delayed

Then, you can assign new accels to GTK menu actions pressing the keys while the option is active.

This was useful to generate random passwords to some webpage users, using the sample code, inside a bash script

Sometimes you have a situation where you cannot properly see the ls output when you are using a terminal w/a dark background. Usually bash has ls aliased to use colors, and you can easily get ls to use the default foreground color via simply unaliasing the command.

works the same as R's t()

Use set +o noclobber and you will be able to replace files again

This will get the job done in the most efficient way -

spawning only one `rm` process.

"On-the-fly" find data is displayed through `tee` and

you should have plenty of time to ctrl-c if needed before it's too late.

You may need to re-run this after major Software Updates.

To leave more languages in, add more ``-and \! -iname "lang*"'' statements:

**Edit: note the 2nd sudo near the end of the pipeline - this is necessary.

Add z to the flags to enable compression.

If the username includes an @ you can use this one:

wget -r --user=username_here --password=pass_here ftp://ftp.example.com

If run in bash, this will display all executables that are in your current $PATH

Run this in the directory you store your music in.

mp3gain and vorbisgain applies the ReplayGain normalization routine to mp3 and ogg files (respectively) in a reversible way.

ReplayGain uses psychoacoustic analysis to make all files sound about the same loudness, so you don't get knocked out of your chair by loud songs after cranking up the volume on quieter ones.

I'm sure this can be piped into another way. Please share!

I used this when I had a directory of movies from a camera. I wanted to watch a little of each movie, then rename it depending on what was in the movie. This did the trick for me.

Listen to different voices in the system--useful for picking the voice you like

cd into the directory that contains the file.

this is just the usual move command but shortcut'd.

say you wanted to move a photo img1.png from ~/photos/holidayphotos into the parent directory which is ~/photos

command would be:

~/photos/holidayphotos$ mv img1.png ..

I use Ubuntu so this'll work in debian but not sure what else.

I put that line in my .bash_profile (OS X) and .bashrc (Linux).

Here is a summary of what the \char means: n=new line, u=user name, h=host, !=history number, w=current work directory

The \[\e[32m\] sequence set the text to bright green and \[\e[0m\] returns to normal color.
