List all groups and the user names that were in each group
"cut" the user names from /etc/passwd and then running a loop over them.

Quick case-insenstive partial filename search
This is a simple command, but extremely useful. It's a quick way to search the file names in the current directory for a substring. Normally people use "ls *term*" but that requires the stars and is not case insensitive. Color (for both ls and grep) is an added bonus.

Provide the ten largest subfolders in the current folder

Binary clock
Fun idea! This one adds seconds and keeps running on the same line. Perl's probably cheating though. :)

Get full from half remembered commands
Show all commands having the part known by you. Eg: $apropos pdf | less

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Rename files in batch

Burn CD/DVD from an iso, eject disc when finished.
cdrecord -scanbus will tell you the (x,y,z) value of your cdr (for example, mine is 3,0,0)

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Quickly analyse an Apache error log
