Check These Out

Enter parameter if empty (script becomes interactive when parameters are missing)
Can be used for command line parameters too. If you have a more complicated way of entering values (validation, GUI, ...), then write a function i.e. EnterValue() that echoes the value and then you can write: $ param=${param:-$(EnterValue)}

Quick and dirty convert to flash
This converts any media ffmpeg handles to flash. It would actually convert anything to anything, it's based on the file extension. It doesn't do ANY quality control, sizing, etc, it just does what it thinks is best. I needed an flv for testing, and this spits one out easily.

wget multiple files (or mirror) from NTLM-protected Sharepoint
If you have to deal with MS Sharepoint which is (rarely, let's hope) used in e.g. certain corporate environments). This uses Cntlm. For single files, just use cURL -- its NTLM authentication works quite well. # /etc/cntlm.conf: # Username account # Domain domain # Password ############ # Proxy 10.20.30.40 (IP of the sharepoint site) # NoProxy * # Listen 3128

List all the files that have been deleted while they were still open.
If your customer deletes a file that is still in use by a process, that space does not get freed up (will not show up in df) until that process either closes the file on its own, or is killed.

pngcrush all .png files in the directory
Nothing too magical here, just uses pngcrush to losslessly compress all your pngs!

archlinux: check which repository packages have updates available
Shows which packages from the official repositories (not aur) have updates available. For most accurate output, the mirrors and package lists should be up to date.

From http://lists.debian.org/debian-devel/2001/01/msg00971.html .

Recursive search and replace (with bash only)
Replaces a string matching a pattern in one or several files found recursively in a particular folder.

Remove specific versions of old kernels (Ubuntu/Debian)
If, for example, you want to remove all kernels and headers but the last three versions, you can't use one of that magic all-in-one "remove old stuff" commands. With this simple but elegant command you can remove a range of versions, or a list of versions with e.g. {14,16,20}.

Press ctrl+r in a bash shell and type a few letters of a previous command
In the sample output, I pressed ctrl+r and typed the letters las. I can't imagine how much typing this has saved me.


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.
