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.

Clean all .pyc files from current project. It cleans all the files recursively.

Count accesses per domain

count the times a domain appears on a file which lines are URLs in the form http://domain/resource.

Binary difference of two files

Upload/download newer version of any file with less size and high speed. To remake the new file use $bspatch

back up your commandlinefu contributed commands

Use `zless` to read the content of your *rss.gz file: $ zless commandlinefu-contribs-backup-2009-08-10-07.40.39.rss.gz

Replace the content of an XML element

Replaces "650" with "999" in simple.xml. xml used - http://www.w3schools.com/xml/simple.xml

view the system memory in clear text

see what's in your memory right now... sometimes you find passwords, account numbers and url's that were recently used. Anyone have a safe command to clear the memory without rebooting?

Lists unambigously names of all xml elements used in files in current directory

This set of commands was very convenient for me when I was preparing some xml files for typesetting a book. I wanted to check what styles I had to prepare but coudn't remember all tags that I used. This one saved me from error-prone browsing of all my files. It should be also useful if one tries to process xml files with xsl, when using own xml application.

Get a qrcode for a given string

Check command history, but avoid running it

!whatever will search your command history and execute the first command that matches 'whatever'. If you don't feel safe doing this put :p on the end to print without executing. Recommended when running as superuser.

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
