Arch Linux sort installed packages by size

This, like the other commands listed here, displays installed arch packages. Unlike the other ones this also displays the short description so you can see what that package does without having to go to google. It also shows the largest packages on top. You can optionally pipe this through head to display an arbitrary number of the largest packages installed (e.g. ... | head -30 # for the largest 30 packages installed) Show Sample Output

Grab a list of MP3s (with full path) out of Firefox's cache Ever gone to a site that has an MP3 embedded into a pesky flash player, but no download link? Well, this one-liner will yank the *full path* of those tunes straight out of FF's cache in a clean list. Shorter and Intuitive version of the command submitted by (TuxOtaku)

Install pip with Proxy

Bash prompt with user name, host, history number, current dir and just a touch of color

I put that line in my .bash_profile (OS X) and .bashrc (Linux). Here is a summary of what the \char means: n=new line, u=user name, h=host, !=history number, w=current work directory The \[\e[32m\] sequence set the text to bright green and \[\e[0m\] returns to normal color. For more information on what you can set in your bash prompt, google 'bash prompt'

Which processes are listening on a specific port (e.g. port 80)

swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Replace spaces in a filename with hyphens

As long as you have perl based rename. You can check: =$ rename --help Unknown option: help Usage: rename [-v] [-n] [-f] perlexpr [filenames] That's the good one.

Command line calculator

This opens a python command line. You can use math and random and float-division is enabled (without appending .0 to integers). I just don't know how to specify a standard precision.

Make vim open in tabs by default (save to .profile)

I always add this to my .profile rc so I can do things like: "vim *.c" and the files are opened in tabs.

Monitoring file handles used by a particular process

-r : repeat mode

Create a mirror of a local folder, on a remote server

Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Show one line summaries of all DEB packages installed on Ubuntu based on pattern search

I sometimes want to know what packages are installed on my Ubuntu system. I still haven't figured out how to use aptitude effectively, so this is the next best thing. This allows finding by name. The grep '^ii' limits the display to only installed packages. If this is not specified, then it includes listing of non-installed packages as well.
