ncdu - ncurses disk usage
ncdu is a text-mode ncurses-based disk usage analyzer. Useful for when you want to see where all your space is going. For a single flat directory it isn't more elaborate than an du|sort or some such thing, but this analyzes all directories below the one you specify so space consumed by files inside subdirectories is taken into account. This way you get the full picture. Features: file deletion, file size or size on disk and refresh as contents change. Homepage: http://dev.yorhel.nl/ncdu

Rename files in batch

Find files modified since a specific date
This command uses -newerXY to show you the files that are modified since a specific date. I recommend looking for "-newerXY" on the manpage to get the specifics.

Add the time to BASH prompt
Adds the time in 12hr AM/PM format to the beginning of a prompt. Change \@ to \t for 24-hour time or \T for 12hr without AM/PM. To keep the time the next time you open a terminal, edit ~/.bashrc and stick the command at the bottom.

A bash timer
Starts and shows a timer. banner command is a part of the sysvbanner package. Instead of the banner an echo or figlet commands could be used. Stop the timer with Ctrl-C and elapsed time will be shown as the result.

Output files without comments or empty lines
Filter comments and empty lines in files. I find this very useful when trying to find what values are actually set in a very long example config file. I often set an alias for it, like : alias nocomment='grep -v "^\($\|#\)"'

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"

notify yourself when a long-running command which has ALREADY STARTED is finished
If you want to be notified when a long-running command is finished, but you have already started it: CTRL+Z $ fg; echo "finished" | sendmail [email protected] I use a script to post a tweet, which sends me a txt: $ fg; echo "finished" | tweet

cp the file
Copy the file with the given .extension at the source file's location. Eliminates the typing of long paths again and again.
