Commands by Dhinesh (13)

What's this? 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.

Check These Out

Replace spaces in filenames with underscores
I realize there's a few of these out there, but none exactly in this form, which seems the cleanest to me

make a list of movies(.m3u).

list block devices
Shows all block devices in a tree with descruptions of what they are.

Get all documents (doc,docx,xls,xlsx,pdf,ppt,pptx,...) linked in a webpage

Enable ** to expand files recursively (>=bash-4.0)
Since bash 4.0, you can use ** to recursively expand to all files in the current directory. This behaviour is disabled by default, this command enables it (you'd best put it in your .profile). See the sample output for clarification. In my opinion this is much better than creating hacks with find and xargs when you want to pass files to an application.

E-mail a traditional Berkeley mbox to another recipient as individual e-mails.

Show the total number of changes that every user committed to a Subversion repository
This saves Subversion's log output as XML and then runs an XQuery over it. This is standard XQuery 1.0 and should therefore also work with other XQuery processors. I have tested it with Zorba ( XQilla ( also does it, but you'd have to save the query to a file and then execute "xqilla filename.xq". The query first finds all distinct authors and then, for each author, sums up the number of paths they have changed in each commit. This accounts for commits of multiple changes at once. The indenting space in all lines from the second one seems to be due to a bug in Zorba.

Colour part of your prompt red to indicate an error
If the return code from the last command was greater than zero, colour part of your prompt red. The commands give a prompt like this: [user current_directory]$ After an error, the "[user" part is automatically coloured red. Tested using bash on xterm and terminal. Place in your .bashrc or .bash_profile.

View an info page on a nice interface
Nice interface for an info page.

Show only existing executable dirs in PATH using only builtin bash commands
Finds executable and existing directories in your path that can be useful if migrating a profile script to another system. This is faster and smaller than any other method due to using only bash builtin commands. See also: + +

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.
