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

You have a python script that slowly prints output, you want to pipe the output to grep or tee, and you are impatient and want to watch the results right away. Rather than modify your script (making it slightly less efficient), use the -u option to have the output unbuffered.

This utilizes the Requests and BeautifulSoup libraries in Python to retrieve a user page on commandlinefu, parse it (error-tolerant) and extract all the lines of the following format: gzip * To print them, a list comprehension is used to iterate over the values, and join() is called on a newline character.

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.

Share Your Commands

set your screensaver as your desktop background MAC OSX

Grep syslog today last hour

Uses date to grep de logfile for today and uses it to get the last hour logs. Can be used to get last minute logs or today's logs.

Check if *hardware* is 32bit or 64bit

This command tell you if your hardware is 32 or 64 bits even if you install a 32bits OS on a 64 bits hardware. If your distro don't support the -q switch, try doing : $ grep &>/dev/null '\' /proc/cpuinfo && echo 64 bits || echo 32 bits

Function to create an alias on the fly

Is used like this: mkalias rmcache "rm -rfv app/cache/*"

Get the size of all the directories in current directory

OSX's BSD version of the du command uses the -d argument instead of --max-depth.

youtube2m3u

generate playlists from youtube ( or othre things that support yt-dlp)

view the system memory in clear text

see what's in your memory right now... sometimes you find passwords, account numbers and url's that were recently used. Anyone have a safe command to clear the memory without rebooting?

Check if port is open on remote machine

Check if port is open, if you don't have ncat on your machine.

Get the Nth argument of the last command (handling spaces correctly)

Bash's history expansion character, "!", has many features, including "!:" for choosing a specific argument (or range of arguments) from the history. The gist is any number after !: is the number of the argument you want, with !:1 being the first argument and !:0 being the command. See the sample output for a few examples. For full details search for "^HISTORY EXPANSION" in the bash(1) man page. Note that this version improves on the previous function in that it handles arguments that include whitespace correctly.

Extracting a range of pages from a PDF, using GhostScript

In this example we extract pages 14-17
