Check These Out

Find 10 largest files in git history

Find and copy files from subdirectories to the current directory

Lists all listening ports together with the PID of the associated process

This command is more portable than it's cousin netstat. It works well on all the BSDs, GNU/Linux, AIX and Mac OS X. You won't find lsof by default on Solaris or HPUX by default, but packages exist around the web for installation, if needed, and the command works as shown. This is the most portable command I can find that lists listening ports and their associated pid.

Find the package that installed a command

Create the directoty recursively

Get all files of particular type (say, PDF) listed on some wegpage (say, example.com)

This example command fetches 'example.com' webpage and then fetches+saves all PDF files listed (linked to) on that webpage. [*Note: of course there are no PDFs on example.com. This is just an example]

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"

Stop Flash from tracking everything you do.

Brute force way to block all LSO cookies on a Linux system with the non-free Flash browser plugin. Works just fine for my needs. Enjoy.

Cut/Copy brackets or parentheses on vim (in normal mode)

We have for example : func () { echo FOO echo BAR } Place the cursor under a bracket and press d + %. It will cut everything inside and the brackets. It let : func () You can copy text with y + %

Add fade in/out to first & last 25 frames of a video

Replace vid.mp4 with the path to your original video file, and out.mp4 to the path where you want to save the new file. To view the output first before saving, remove "-consumer avformat:out.mp4" from the end.
