Use mplayer to save video streams to a file
I use this command to save RTSP video streams over night from one of our national TV stations, so I won't have to squeeze the data through my slow internet connection when I want to watch it the next day. For ease of use, you might want to put this in a file: #!/bin/bash FILE="`basename \"$1\"`" mplayer -dumpstream -dumpfile "$FILE" -playlist "$1"

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.

Create a new file

Find the process you are looking for minus the grepped one
faster ;) but your idea is really cool

easily find megabyte eating files or directories
This is easy to type if you are looking for a few (hundred) "missing" megabytes (and don't mind the occasional K slipping in)... A variation without false positives and also finding gigabytes (but - depending on your keyboard setup - more painful to type): $du -hs *|grep -P '^(\d|,)+(M|G)'|sort -n (NOTE: you might want to replace the ',' according to your locale!) Don't forget that you can modify the globbing as needed! (e.g. '.[^\.]* *' to include hidden files and directories (w/ bash)) in its core similar to: http://www.commandlinefu.com/commands/view/706/show-sorted-list-of-files-with-sizes-more-than-1mb-in-the-current-dir

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"

find filenames and directory names that doesn't conform ISO 9660 level 2
You might want to check what file and directory names would be renamed or chopped if you create iso 9660 level 2 image out of them. Use this command to check first.

Get your outgoing IP address

Add an audio soundtrack to a series of images to create an flv
Creates a 5 minute flv file, with the given sequence of images and audio with 0.5 fps. The images were created using the following command: for x in `seq 0 300`; do cp ../head.PNG head-`printf '%03d' $x`.png; done You can also inject metadata to seek easier using yamdi as follows: yamdi -i muxed.flv -o video.flv

Create a directory and go inside it
$_ expands to the last argument of the last command that was executed
