  • Just add this function to your .zshrc / .bashrc, and by typing "shout *URL*" you get a randomly chosen English word that ShoutKey.com uses to short your URL. You may now go to shoutkey.com/*output_word* and get redirected. The URL will be valid for 5 minutes. (I've never used sed before, so I'll be quite glad if someone could straighten up the sed commands and combine them (perhaps also removing the whitespace). If so, I'll update it right away ;) ) Show Sample Output


    4
    shout () { curl -s "http://shoutkey.com/new?url=$1" | sed -n 's/\<h1\>/\&/p' | sed 's/<[^>]*>//g;/</N;//b' ;}

  • like 7300, but doesn't clutter your working directory with old qr.*.png files. This will get the QR barcode, and send it right into ImageMagick's 'display' tool. Usage is the same as 7300; just call this function followed by the URL: qrurl http://xkcd.com


    4
    qrurl() { curl -sS "http://chart.apis.google.com/chart?chs=200x200&cht=qr&chld=H|0&chl=$1" -o - | display -filter point -resize 600x600 png:-; }

    ljmhk · 2011-04-11 14:08:50 5
  • Just an alternative with more advanced formating for readability purpose. It now uses colors (too much for me but it's a kind of proof-of-concept), and adjust columns. Show Sample Output


    3
    curl -u username --silent "https://mail.google.com/mail/feed/atom" | awk 'BEGIN{FS="\n";RS="(</entry>\n)?<entry>"}NR!=1{print "\033[1;31m"$9"\033[0;32m ("$10")\033[0m:\t\033[1;33m"$2"\033[0m"}' | sed -e 's,<[^>]*>,,g' | column -t -s $'\t'

  • With the "--resolve" switch, you can avoid doing DNS lookups or edit the /etc/hosts file, by providing the IP address for a domain directly. Useful if you have many servers with different IP addresses behind a load balancer. Of course, you would loop it: for IP in 10.11.0.{1..10}; do curl --resolve subdomain.example.com:80:$IP subdomain.example.com -I -s; done


    3
    curl --resolve subdomain.example.com:80:10.100.0.1 subdomain.example.com -I -s

  • Alternative to the ping check if your firewall blocks ping. Uses curl to get the landing page silently, or fail with an error code. You can probably do this with wget as well. Show Sample Output

  • This version prints current votes and commands for a user. Pass the user as an argument. While this technically "fits" as a one liner, it really is easier to look at as a shell script with extra whitespace. :) Show Sample Output


    2
    curl -s http://www.commandlinefu.com/commands/by/$1/xml | awk -F'</?div[^>]*>' '/class=\"command\"/{gsub(/&quot;/,"\"",$2); gsub(/&lt;/,"<",$2); gsub(/&gt;/,">",$2); gsub(/&amp;/,"\\&",$2); cmd=$2} /class=\"num-votes\"/{printf("%3i %s\n", $2, cmd)}'

  • There's another version on here that uses GET but some people don't have lwp-request, so here's an alternative. It's also a little shorter and should work with most youtube URLs since it truncates at the first &


    2
    url="[Youtube URL]"; echo $(curl ${url%&*} 2>&1 | grep -iA2 '<title>' | grep '-') | sed 's/^- //'
    rkulla · 2010-04-29 02:03:36 4
  • In this example 'git' is the user name and the output format is YAML but you can change this to XML or JSON, eg: curl http://github.com/api/v1/json/usernamehere Show Sample Output


    2
    curl http://github.com/api/v1/yaml/git
    rkulla · 2010-05-30 00:18:00 6
  • In this example we search for 'vim' but vim doesn't have a project on github right now. That's ok, this command still searches for every project that has 'vim' in their description (forks, plugins, etc). To get XML or JSON output just replace 'yaml' in the url with 'xml' or 'json'. Show Sample Output


    2
    curl http://github.com/api/v1/yaml/search/vim

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


Check These Out

Compare two files side-by-side
I found out about this from Unix Power Tools, and thought it was pretty useful. Use the -w option to change the width of the output, and the -s option to suppress lines that are the same in both files.

list block devices
Shows all block devices in a tree with descruptions of what they are.

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"

Figure out what shell you're running
short, sweet, and works after sudoing a new shell.

watch iptables counters
This will allow you to watch as matches occur in real-time. To filter out only ACCEPT, DROP, LOG..etc, then run the following command: watch 'iptables -nvL | grep -v "0 0" && grep "ACCEPT"' The -v is used to do an inverted filter. ie. NOT "0 0"

How to copy CD/DVD into hard disk (.iso)
A dear friend of mine asked me how do I copy a DVD to your hard drive? If you want to make a copy of the ISO image that was burned to a CD or DVD, insert that medium into your CD/DVD drive and (assuming /dev/cdrom is associated with your computer?s CD drive) type the following command

Detect illegal access to kernel space, potentially useful for Meltdown detection
Based on capsule8 agent examples, not rigorously tested

Create a mirror of a local folder, on a remote server
Create a exact mirror of the local folder "/root/files", on remote server 'remote_server' using SSH command (listening on port 22) (all files & folders on destination server/folder will be deleted)

Show interface/ip using awk
Interfaces like lo can be omitted from the beginning, there are probably better ways of doing this, i'm a noob at awk.

Re-use the previous command output
The $(!!) will expand to the previous command output (by re-running the command), which becomes the parameter of the new command newcommand.
