In my case it was actually like this...

Restore user,group and mod of an entire website
I often use it at my work, on an ovh server with root ssh access and often have to change mod after having finished an operation. This command, replace the user, group and mod by the one required by apache to work.

Use bash history with process substitution
Bash has a great history system of its commands accessed by the ! built-in history expansion operator (documented elsewhere on this site or on the web). You can combine the ! operator inside the process redirection

Open the last file you edited in Vim.

Command to logout all the users in one command
Logs all users out except root. I changed the grep to use a regexp in case a user's username contained the word root.

run command on a group of nodes in parallel

delete all bitbucket repos via rest API v2 (req: jq and curl)
bitbucket paginates at around 1360 characters, so if you have several pages of repos in git hub you can just add "?page={1..4}" the url used to get all the repos. you can also use -v for the deletion curl if you want to see the response from the server.

Get current stable kernel version string from kernel.org
depends on "jq" This is more reliable in my opinion.

Calculate pi to an arbitrary number of decimal places
Change the scale to adjust number of decimal places prefix the command with "time" to benchmark the computer (compare how long it takes to calculate 10000 digits of pi on various computers).
