Check These Out
in loop, until the last port (65535), list all opened ports on host.
in the sample I used localhost, but you can replace with any host to test.
The biggest advantage over atoponce's nifty original is not killing the scrollback. Written assuming bash, but shouldn't be terribly difficult to port to other shells. S should be multiple spaces, but I can't get commandlinefu to save/show them properly, any help?

I was surprised to find that with RedHat bash, I could not find any comment lines (begining with #) in my bash shell history. Surprised because in Mageia Linux this works. It turns out that RedHat's bash will keep comment lines if in my .bashrc, I define:
export HISTIGNORE=' cd "`*: PROMPT_COMMAND=?*?'
Why have comment lines in shell history? It's a handy and convenient way to make proto-commands (to be completed later) and for storing brief text data that is searchable in shell history.
This does the following:
1 - Search recursively for files whose names match REGEX_A
2 - From this list exclude files whose names match REGEX_B
3 - Open this as a group in textmate (in the sidebar)
And now you can use Command+Shift+F to use textmate own find and replace on this particular group of files.
For advanced regex in the first expression you can use -regextype posix-egrep like this:
mate - `find * -type f -regextype posix-egrep -regex 'REGEX_A' | grep -v -E 'REGEX_B'`
Warning: this is not ment to open files or folders with space os special characters in the filename. If anyone knows a solution to that, tell me so I can fix the line.
This command will automatically find the latest version of the file that was deleted and restore it to it's previous location. If, of course, your file was kept in a git repository...
I found this command on http://stackoverflow.com/a/1113140
Use the AWS CLI tools to generate a list instances, then pipe them to JQ to show only their launch time and instance id. Finally use sort to bring them out in runtime order. Find all those instances you launched months ago and have forgotten about.
You can watch channels of your freebox, everywhere. With " vlc http://your-ip:12345 " on the client and ncurses vlc interface on the host. et voila
