List all files modified by a command
This lists all files modified after calling some command using a temporal anchor.

Discover the process start time
That is useful to discover the start time of process older than 1 day. You can also run: $ ls -ld /proc/PID That's returning the creation date of the proc files from the process. Some users reported that this way might show you a wrong date since any other process like cron, for example, could change this date.

List files in directory tree with newest last

password recovery on debian
Appended to grub boot parameters ... gives shell ... password recovery

Database size
Mysql command to list the disk usage of the database

Selecting a random file/folder of a folder
Also looks in subfolders

Default value or argument
I used it for this function, which prints hashes: function liner { num_lines=${1:-42} echo printf %${num_lines}s|tr " " "#" echo } Note the colon-dash, instead of the usual colon-equals.

Show linux kernel modules dependencies
Use modprobe to list all the dependencies of a certain kernel module. Handy when debugging system issues.

Quick HTML image gallery
My take on the original: even though I like the other's use of -exec echo, sed just feels more natural. This should also be slightly easier to improve. I expanded this into a script as an exercise, which took about 35 minutes (had to look up some docs): http://bitbucket.org/kniht/nonsense/src/7c1b46488dfc/commandlinefu/quick_image_gallery.py
