MP3 player

I tried a few curses based mp3 players for playing back choir practice songs for my wife. Unfortunately none of the ones I tried were capable of scrubbing a track. Firefox saves the day.

Recursive cat - concatenate files (filtered by extension) across multiple subdirectories into one file

Useful if you have to put together multiple files into one and they are scattered across subdirectories. For example: You need to combine all .sql files into one .sql file that would be sent to DBAs as a batch script. You do get a warning if you create a file by the same extension as the ones your searching for. find . -type f -name *.sql -exec cat {} > BatchFile.txt \;

Create a DOS floppy image

mount with: mount -t msdos -o loop ./floppy.img /tmp/mnt

Find files containing string and open in vim

I often use "vim -p" to open in tabs rather than buffers.

cp the file

Copy the file with the given .extension at the source file's location. Eliminates the typing of long paths again and again.

Updating the status on identi.ca using curl.

identica is an open source social networking and micro-blogging service. Based on Laconica, a micro-blogging software package built on the OpenMicroBlogging specification. http://identi.ca/

list block devices

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

Resize an image to at least a specific resolution

This command will resize an image (keeping the aspect ratio) to a specific resolution, meaning the resulting image will never be smaller than this resolution. For example, if we have a 2048x1000 image, the output would be 1229x600, not 1024x600 or 1024x500. Same thing for the height, if the image is 2000x1200, the output would be 1024x614.

Automatically download Ubuntu 10.04 when available

Tested with 9.10 release. Choose whatever torrent client you prefer.

Quick HTML image gallery from folder contents with Perl

This includes a title attribute so you can see the file name by hovering over an image. Also will hoover up any image format - jpg, gif and png.
