FizzBuzz one-liner in Python

A common programming question for interviewers to ask potential job candidates is to code "FizzBuzz". That is, if a number is divisible by 3, then it should display "Fizz". If a number is divisible by 5, it should display "Buzz". If it is divisible by both, then it should display "FizzBuzz". Otherwise, display the current number between 1 and 100. Show Sample Output

What's this?

commandlinefu.com is the place to record those command-line gems that you return to again and again. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Find the 10 users that take up the most disk space

In OSX you would have to make sure that you "sudo -s" your way to happiness since it will give a few "Permission denied" errors before finally spitting out the results. In OSX the directory structure has to start with the "Users" Directory then it will recursively perform the operation. Your Lord and master, Mematron

Convert a bunch of HTML files from ISO-8859-1 to UTF-8 file encoding in a folder and all sub-folders

This is my first attempt at converting all HTML files to UTF-8 file encoding, including all subfolders. Theres probably a much more compact way to do it, but I'm quite proud of it with my windows background ;)

Uptime in minute

Want to run scripts/programs in the system after starting X minute [ For letting the system to free ]? This will give uptime in minute.

list files recursively by size

Find the most recent snapshot for an AWS EBS volume

Uses the python-based AWS CLI (https://aws.amazon.com/cli/) and the JSON query tool, JQ (https://stedolan.github.io/jq/)

Adding Prefix to File name

Good old bracket expansion :-) For large numbers of files, "rename" will spare you the for-loop, or the find/exec...

Display last exit status of a command

The variable ? contain the last exit status of a command, it can be printed for troubleshooting purpose.

grep certain file types recursively

doesn't do case-insensitive filenames like iname but otherwise likely to be faster

List only executables installed by a debian package

Maybe not clean with big package and too long argument. But return every file who can be executed.

Copy your ssh public key to a server from a machine that doesn't have ssh-copy-id

This one is a bit more robust -- the remote machine may not have an .ssh directory, and it may not have an authorized_keys file, but if it does already, and you want to replace your ssh public key for some reason, this will work in that case as well, without duplicating the entry.
