List only directory names
This command would be useful when it is desirable to list only the directories. Other options Hidden directory $ ls -d .*/ Other path $ ls -d /path/to/top/directory/.*/ Long format: $ ls -ld */

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

ps grep with header
Yet another ps grep function, but this one includes the column headings.

Replace spaces in filenames with underscorees

Convert flv without re-encoding

Increment the filename of png in a given directory by one

Set a Reminder for yourself via the notification system
This will be seen through your system's visual notification system, notify-osd, notification-daemon, etc. --- sleep accepts s,m,h,d and floats (date; sleep .25m; date) --- notify-send (-t is in milliseconds && -u low / normal / critical) man notify-send for more information --- notification-daemon can use b/i/u/a HTML

pretend to be busy in office to enjoy a cup of coffee
Not as taxing on the CPU.

Create a bunch of dummy files for testing
Sometimes I need to create a directory of files to operate on to test out some commandlinefu I am cooking up. The main thing is the range ({1..N}) expansion.

merge a.pdf b.pdf and c.pdf and create ./out.pdf
