Check These Out

generate iso

List only the directories

Lists all files and directories with modified time newer than a given date
This is great for looking for files that have been updated recently. Logs especially or monitoring what files were added during an install.

Random numbers with Ruby
There's been a few times I've needed to create random numbers. Although I've done so in PERL, I've found Ruby is actually faster. This script generates 20 random "10" digit number NOT A RANDOM NUMBER. Replace 20 (1..20) with the amount of random numbers you need generated

load changes without logging in and out vim
src: daily vim blog

Set all CPU cores' CPU frequency scaling governor to maximum performance

List your largest installed packages.
Calculates the size on disk for each package installed on the filesystem (or removed but not purged). This is missing the $ | sort -rn which would put the biggest packges on top. That was purposely left out as the command is slightly on the slow side Also you may need to run this as root as some files can only be checked by du if you can read them ;)

Count all files in directories recursively with find
Counts the files present in the different directories recursively. One only has to change maxdepth to have further insight in the directory hierarchy. Found at unix.stackexchange.com: http://unix.stackexchange.com/questions/4105/how-do-i-count-all-the-files-recursively-through-directories

find all non-html files

Show bash's function definitions you defined in .bash_profile or .bashrc
If you omit the function name, the command will display all definitions
