This is a slightly modified version of http://www.commandlinefu.com/commands/view/4283/recursive-search-and-replace-old-with-new-string-inside-files (which did not work due to incorrect syntax) with the added option to sed inside only files named filename.ext

create an emergency swapfile when the existing swap space is getting tight

Create a temporary file that acts as swap space. In this example it's a 1GB file at the root of the file system. This additional capacity is added to the existing swap space.

recursive search and replace old with new string, inside files

Using -Z with grep and -0 with xargs handles file names with spaces and special characters.

Install pip with Proxy

Installs pip packages defining a proxy

Get file access control list

List all execs in $PATH, usefull for grepping the resulting list

##Dependancies: bash coreutils Many executables in $PATH have the keyword somewhere other than the beginning in their file names. The command is useful for exploring the executables in $PATH like this. $ find ${PATH//:/ } -executable -type f -printf "%f\n" |grep admin lpadmin time-admin network-admin svnadmin users-admin django-admin shares-admin services-admin

Stop Flash from tracking everything you do.

Brute force way to block all LSO cookies on a Linux system with the non-free Flash browser plugin. Works just fine for my needs. Enjoy.

List your largest installed packages (on Debian/Ubuntu)

dpigs is in the package debian-goodies (debian/ubuntu)

list all file extensions in a directory

Pack up some files into a tarball on a remote server without writing to the local filesystem

I recently found myself with a filesystem I couldn't write to and a bunch of files I had to get the hell out of dodge, preferably not one at a time. This command makes it possible to pack a bunch of files into a single archive and write it to a remote server.
