Check These Out

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"

Pack up some files into a tarball on a remote server without writing to the local filesystem
I recently found myself with a filesystem I couldn't write to and a bunch of files I had to get the hell out of dodge, preferably not one at a time. This command makes it possible to pack a bunch of files into a single archive and write it to a remote server.

Most simple way to get a list of open ports

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

Another Curl your IP command
Just another curl command to get your public facing IP

a function to create a box of '=' characters around a given string.
First argument: string to put a box around. Second argument: character to use for box (default is '=') Same as command #4962, cleaned up, shortened, and more efficient. Now a ' * ' can be used as the box character, and the variables get unset so they don't mess with anything else you might have. They marked c++ as a function for this command, but I'm not sure why. Must be a bug.

Makefile argument passing
This would allow reference of $(VAR) (if defined) with the value 'foobar' within the Makefile.

Convert (almost) any video file into webm format for online html5 streaming

Check if your ISP is intercepting DNS queries
It's somewhat common ISPs to intercept DNS queries at port 53 and resolve them at their own. To check if your ISP is intercepting your DNS queries just type this command in the terminal. "#.abc" it's an OK answer. But if you get something like "I am not an OpenDNS resolver.", yep, you are beign cheated by your ISP.
