Archive all SVN repositories in platform indepenent form
This command dumps all SVN repositories inside of folder "repMainPath" (not recursively) to the folder "dumpPath", where one dump file will be created for each SVN repository.

copy from host1 to host2, through your host
Good if only you have access to host1 and host2, but they have no access to your host (so ncat won't work) and they have no direct access to each other.

Big Countdown Clock with hours, minutes and seconds
Figlet is easy to find for download on the internet, and works for any text. Quite cool.

Check the current price of Bitcoin in USD

Recursively Find Images, Convert to JPEGS and Delete
Simple command to convert a large number of images into jpeg-format. Will delete originals after conversion.

Exclude .svn, .git and other VCS junk for a pristine tarball
~$ tar --version tar (GNU tar) 1.20

Append stdout and stderr to a file, and print stderr to the screen [bash]
Useful for cron jobs -- all output will be logged but only errors will cause email to be sent. NB the order of "2>&1" and ">> logfile" is important, it doesn't work if you reverse them (everything goes to the logfile, nothing left for tee).

Create a square thumbnail or favicon using ImageMagick
Resize `file.png` to a 32x32 px image. Use a value other than 32 to create other icon sizes (e.g. 16x16 or 32x32). Combine two favicon sizes using: `convert icon-16px.png icon-32px.png favicon.ico` For a social media preview image, use `2:1#` for the extent and `1200` for the scale.

Numbers guessing game
Felt like I need to win the lottery, and wrote this command so I train and develop my guessing abilities.
