Generate background office noise using Digg feeds and OSX.

Instead of having someone else read you the Digg headlines, Have OSX do it. Requires Curl+Sed+Say. This could probably be easily modified to use espeak for Linux.

Resample MP3's to 44.1kHz

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

purge installed but unused linux headers, image, or modules

will purge: only installed apps: /^ii/!d avoiding current kernel stuff: /'"$(uname -r | sed "s/$.*$-$[^0-9]\+$/\1/")"'/d using app names: s/^[^ ]* [^ ]* $[^ ]*$.*/\1/ avoiding stuff without a version number: /[0-9]/!d

Control ssh connection

SSH can be controlled trough an ~ escape sequence. Example, to terminate the current ssh connection, type a newline, then the ~ character, and last a . character. This is useful eg when an ssh connection hangs after you reboot a machine and the connection hangs.

Remove embedded fonts from a pdf.

It's sometimes useful to strip the embedded fonts from a pdf, for importing into something like Inkscape. Be warned, this will increase the size of a pdf substantially. I tried this with only gs writing with -sDEVICE=pdfwrite but it doesn't seem to work, so I just pipe postscript output to ps2pdf for the same effect.

Google URL shortener

Use curl and sed to shorten an URL using goo.gl without any other api

Copy all files, including hidden files, recursively without traversing backward

You could do the following, however, brace expansion with {} is not defined in POSIX, and therefore not guaranteed to work in all shells. But, if it does, it's more convenient (although it's certainly not less typing): $ cp -r {*,.??*} /dest Sometimes there are times when I need to cp(1), mv(1) or rm(1) files recursively, but don't want to traverse the previous directory by following ../../../../ etc out of the current directory. This command prevents that. The secret sauce is ".??*". The file globbing ensures that it must start with a dot, and be followed by at least two characters. So, three characters must exist in the filename, which eliminates "." and "..".

Convert JSON to YAML

Find usb device

I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

Find usb device in realtime

Using this command you can track a moment when usb device was attached.

this toggles mute on the Master channel of an alsa soundcard

File rotation without rename command

Rotates log files with "gz"-extension in a directory for 7 days and enumerates the number in file name. i.e.: logfile.1.gz > logfile.2.gz I needed this line due to the limitations on AIX Unix systems which do not ship with the rename command.
