Renaming files removing some unwanted extension

For those files in current folder that would be shown in `ls *ext`, for some extension ext, move/rename that file removing the .ext suffix from the file name. It uses Bash's parameter substitution, as seen in http://tldp.org/LDP/abs/html/parameter-substitution.html#PCTPATREF (for analog use in prefix, see http://tldp.org/LDP/abs/html/parameter-substitution.html#PSOREX2 )
This is sample output - yours may be different.

for i in *ext; do mv $i ${i%.ext}; done

Move mp3 files to another path with existing subtree structure

Use case: folder with flac files with tree structure ../artist/album/number-title.flac 1) convert flac->mp3 in the same folder: http://www.commandlinefu.com/commands/view/6341/convert-all-.flac-from-a-folder-subtree-in-192kb-mp3 2) search for mp3 files and recreate tree structure to another path: http://www.commandlinefu.com/commands/view/8853/copy-selected-folder-found-recursively-under-src-retaining-the-structure 3) move all mp3 files to that new folder: this command

find . -iname "*.mp3" -type f -print0 | xargs -0 -I '{}' mv {} /new/path/to/mp3/{}

copy selected folder found recursively under src retaining the structure

It's not better than the former, just another possible way. Found at http://www.linuxquestions.org/questions/linux-newbie-8/copy-directory-structure-only-208796/ Credits to whansard The command finds all .mp3 files in all subfolders from where it's ran, catches its "relative path" and creates inside /new/path/ with the same "relative path". PS: /new/path/ must exists Use case: folder with flac files with tree structure ../artist/album/number-title.flac 1) convert flac->mp3 in the same folder: http://www.commandlinefu.com/commands/view/6341/convert-all-.flac-from-a-folder-subtree-in-192kb-mp3 2) search for mp3 files and recreate tree structure to another path: this command 3) move all mp3 files to that new folder: http://www.commandlinefu.com/commands/view/8854/move-mp3-files-to-another-path-with-existing-subtree-structure Show Sample Output

Convert all .flac from a folder subtree in 192Kb mp3

find . -type f -iname '*.flac' # searches from the current folder recursively for .flac audio files | # the output (a .flac audio files with relative path from ./ ) is piped to while read FILE; do FILENAME="${FILE%.*}"; flac -cd "$FILE" | lame -b 192 - "${FILENAME}.mp3"; done # for each line on the list: # FILE gets the file with .flac extension and relative path # FILENAME gets FILE without the .flac extension # run flac for that FILE with output piped to lame conversion to mp3 using 192Kb bitrate Show Sample Output

Clean up after a poorly-formed tar file

These days, most software distributed in tar files will just contain a directory at the top level, but some tar files don't have this and can leave you with a mess of files in the current folder if you blindly execute $ tar zxvf something.tar.gz This command can help you clean up after such a mistake. However, note that this has the potential to do bad things if someone has been *really* nasty with filenames.

ignore the .svn directory in filename completion

When browsing java source code (for example) it's really annoying having to type the first letter of the package when there is only one package in the subdir. man bash for more info about FIGNORE

Blue Matrix

Same as original, but works in bash

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Convert every eps in a directory to pdf

Converts every *.eps file to a *.pdf file

Sort lines on clipboard

Does the same thing in environments where you have "xclip" instead of "pbpaste"/"pbpate" and "pbcopy".

print all except first collumn

list files recursively by size

Single use vnc-over-ssh connection

This command 1. SSH into a machine 2. Tunnels VNC port to your local computer ("-L 5900:localhost:5900") 3. Runs a single use vnc server ("x11vnc -safer -localhost -nopw -once -display :0") 4. Goes into the background ("-f") 5. Runs VNC viewer on the local computer connecting to the remote machine via the newly created SSH tunnel ("vinagre localhost:5900")

Read info(1) pages using 'less' instead of GNU Texinfo

I like man pages, and I like using `less(1)` as my pager. However, most GNU software keeps the manual in the 'GNU Texinfo' format, and I'm not a fan of the info(1) interface. Just give me less. This command will print out the info(1) pages, using the familiar interface of less!
