What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again.

Delete that bloated snippets file you've been using and share your personal repository with the world. 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.

If you have a new feature suggestion or find a bug, please get in touch via http://commandlinefu.uservoice.com/

Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Remote Serial connection redirected over network using SSH

Requires software found at: http://lpccomp.bc.ca/remserial/

Remote [A] (with physical serial port connected to device)

./remserial -d -p 23000 -s "115200 raw" /dev/ttyS0 &

Local [B] (running the program that needs to connect to serial device)

Create a SSH tunnel to the remote server:

ssh -N -L 23000:localhost:23000 user@hostwithphysicalserialport

Use the locally tunnelled port to connect the local virtual serial port to the remote real physical port:

./remserial -d -r localhost -p 23000 -l /dev/remser1 /dev/ptmx &

Example: Running minicom on machine B using serial /dev/remser1 will actually connect you to whatever device is plugged into machine A's serial port /dev/ttyS0.

List image attributes from a folder of JPEG images

Runs the identify command (from ImageMagick) on each jpg file in the current directory and returns image details according to the format parameter. The example here returns:

Filename FileSize Compression Width Height

More information about the available format options can be found here: http://www.imagemagick.org/script/escape.php

I usually redirect the output to a text file using "> listofdetails.txt" at the end. Spreadsheet magic can then be applied.
