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.

Write comments to your history.

A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Convert ascii string to hex

Here's a version that uses perl. If you'd like a trailing newline: $ perl -pe 's/(.)/sprintf("\\x%x", ord($1))/eg; END {print "\n"}'

Check the current price of Bitcoin in USD

Change the extension of a filename by using rename to convert

This will change all files ending in .JPG to .jpg and will work with any file extension

Ctrl+S Ctrl+Q terminal output lock and unlock

These are simple shortcuts to pause and continue terminal output, works in most terminals and screen multiplexers like screen. You can use it to catch something if things change too fast, and scroll with Shift + PgUp PgDown. On linux console ScrollLock can also be used.

Download all music files off of a website using wget

This will download all files of the type specified after "-A" from a website. Here is a breakdown of the options: -r turns on recursion and downloads all links on page -l1 goes only one level of links into the page(this is really important when using -r) -H spans domains meaning it will download links to sites that don't have the same domain -nd means put all the downloads in the current directory instead of making all the directories in the path -A mp3 filters to only download links that are mp3s(this can be a comma separated list of different file formats to search for multiple types) -e robots=off just means to ignore the robots.txt file which stops programs like wget from crashing the site... sorry http://example/url lol..

ping as traceroute

This command uses ping to get the routers' IP addresses to the destination host as traceroute does. If you know what I mean..

Change prompt to MS-DOS one (joke)

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"
