Commands using ln

shell function which allows you to tag files by creating symbolic links directories in a 'tags' folder.

The tag function takes a tag name as its first argument, then a list of files which take that tag. The directory $HOME/tags/tagname will then hold symbolic links to each of the tagged files. This function was modified from bartonski's (http://www.commandlinefu.com/commands/view/10216) inspired by tmsu (found at https://bitbucket.org/oniony/tmsu/wiki/Home) with readlink function by flxndn (http://www.commandlinefu.com/commands/view/10222).

Example:

This will create $HOME/tags/dog which contains symbolic links to airedale.txt .shizturc and weimeraner.pl

This variation can handle file paths containing spaces.

It's useful mostly for your custom scripts, which running on specific host and tired on ssh'ing every time when you need one simple command (i use it for update remote apt repository, when new package have to be downloaded from another host).

Don't forget to set up authorization by keys, for maximum comfort.

If you use colored ls(1), the broken symbolic links significantly differ from regular files and directories in the ls listing. In my case it is bright red. 0 is for getting the first place in the list.

This command will place symbolic links to files listed in an m3u playlist into a specified folder. Useful for uploading playlists to Google Music.

prefix = The full path prefix to file entries in your .m3u file, if the file paths are relative. For example, if you have "Music/folder/song.mp3" in your list.m3u, you might want to specify "/home/username" as your prefix.

list.m3u = Path to the playlist

target_folder = Path to the target folder in which you would like to create symlinks

Instead of deleting an existing symlink and then re-creating it pointing at the new location, it is possible to perform the same action with this one command.

Interesting discussion on whether this is possible to do atomically here: http://answers.google.com/answers/threadview?id=526119

A safer way to block adobe and macromedia flash tracking and spyware

Newer versions of the flashplayer browser plugin delete the tmp flash video immediately after opening a filehandle to prevent the user from "exporting" the video by simply copying the /tmp/FlashXYZ file. This command searches such deleted flash videos and creates symbolic links to the opened filehandle with the same name as the deleted file.

This allows you to play your flash-videos (from e.g. youtube) with e.g. mplayer or copy the buffered video if you want to keep it.

Brute force way to block all LSO cookies on a Linux system with the non-free Flash browser plugin. Works just fine for my needs. Enjoy.

If you want to pull all of the files from a tree that has mixed files and directories containing files, this will link them all into a single directory. Beware of filesystem files-per-directory limits.

-n: dereference the existing link

-v: (optional) to be sure of what is being done

-f: force the deletion of the existing one

-s: creates a symlink

Be careful: the destination can also be a file or a directory and it will be overwritten.

ln

Remove your BASH history and then link it to /dev/null

This will mv all your mp3 files in the current directory to $ARTIST/$ALBUM/$NAME.mp3

Make sure not to use sudo - as some weird things can happen if the mp3 file doesn't have id3 tags.

When you don't have c_rehash handy. Really simple - if you have a .pem file that doesn't really contain a x509 cert (let's say, newreq.pem), it will create a link, simply called '.0', pointing to that file.

Used for moving stuff around on a fileserver
