Commands using xargs

you could redirect output to /dev/NULL

When downloading files on a Mac, Apple adds the x-attribute: com.apple.quarantine. Often, this makes it so you can't even run a ./configure. This command gets rid of the quarantine for all files in the current directory.

Using a for loop, rename all files with .MP3 extension to .mp3.

defunct processes (zombies) usually have to be killed by killing their parent processes. this command retrieves such zombies and their immediate parents and kills all of the matching processes.

Doesn't depend on curl and doesn't use thumbnails as wallpaper (which has the unfortunate effect of only allowing imgur links)

be careful where you execute this from

do a 'sudo ls' beforehand to prime sudo to not ask for your password

Remove all zero size files from current directory. Its a not recursive option like:

find . -size 0c -exec rm {} \;

Written for Mac OSX. When you are working in a project and want to open it on Github.com, just type "gh" and your default browser will open with the repo you are in. Works for submodules, and repo's that you don't own.

You'll need to copy / paste this command into a gh.sh file, then create an alias in your bash or zsh profile to the gh.sh script. Detailed instructions here if you still need help:

Sometimes cache-files or garbage gets added to your SVN repository. This is the way I normally clean up those when the actual files are already gone.

When I do a major change in my entities, I want to find a way to find all my Entities names and create the commande for me.

So instead of doing ls src/Your/OwnBundle... and then do it manually, this helps a lot.

Search for files and list the 20 largest.

gives us a list of file, recursively, starting from here (.)

separate the names of files with NULL characters, so we're not confused by spaces

then xargs run the du command to find their size (in human-readable form -- 64M not 64123456)

use sort to arrange the list in size order. sort -h knows that 1M is bigger than 9K

finally only select the top twenty out of the list

from my bashrc ;)

This command finds all files in a folder recursively and sets owner and group to read and write. Leaves all dirs intact. This command does takes care of file names with spaces as well.

Like the original version except it does not include the parent apache process or the grep process and adds "sudo" so it can be run by user.

Helps to fix permissions when a user clobbers them in their home directory or elsewhere. Does not rely on file extension, but uses the `file` command for context.

Improvement on Coderjoe's Solution. Gets rid of grep and cut (and implements them in awk) and specifies some different mplayer options that speed things up a bit.

* grep -i leaves only mp3 files (case insentitive)

* sort -R randomizes list (may use GNU 'shuf' instead).

* the sed command will add double quotes around each filename (needed if odd characters are present)

You must spezify /where folder and / folder

If you have another camera you must experiment with Exif data (after -g and after grep) and mask of your photo files IMG_????.JPG

I have do it on Knoppix 6.7.0

You must have installed exiv2.

Marks all manually installed deb packages as automatically installed. Usefull to combine with
