    Shorter and made into a function. Show Sample Output

  • Create an easy to pronounce shortened URL from CLI

    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' ;}

  • Create QR codes from a URL.

    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:-; }

  • Check your unread Gmail from the command line

    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'

  • Test load balancers

    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

  • Check a server is up. If it isn't mail me.

    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


    2
    curl -fs brandx.jp.sme 2&>1 > /dev/null || echo brandx.jp.sme ping failed | mail -ne -s'Server unavailable' joker@jp.co.uk

  • Get your commandlinefu points (upvotes - downvotes)

    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)}'

  • Which Twitter user are you?

    This will tell you which twitter user you are chronologically. For example, a number of 500 means you were the 500th user to create a twitter account. Show Sample Output

  • Grab just the title of a youtube video

    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/^- //'

  • Get info about a GitHub user

    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
  • Get info about a GitHub project

    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

Stoppable sleep
A nice way to interrupt a sleep with a signal.

Copy an element from the previous command
'n' is a non-negative integer. Using 0 will expand to the name of the previous command.

Annoying PROMPT_COMMAND animation
unset PROMPT_COMMAND to disable.

Use /dev/full to test language I/O-failsafety
The Linux /dev/full file simulates a "disk full" condition, and can be used to verify how a program handles this situation. In particular, several programming language implementations do not print error diagnostics (nor exit with error status) when I/O errors like this occur, unless the programmer has taken additional steps. That is, simple code in these languages does not fail safely. In addition to Perl, C, C++, Tcl, and Lua (for some functions) also appear not to fail safely.

Remove color codes (special characters) with sed
Removes ANSI color and end of line codes to the [{attr1};...;{attrn}m format.

Terminal Escape Code Zen - Strace and Tput
Depending on the TERM, the terminfo version, ncurses version, etc.. you may be using a varied assortment of terminal escape codes. With this command you can easily find out exactly what is going on.. This is terminal escape zen! $ ( 2>&2 strace -f -F -e write -s 1000 sh -c 'echo -e "initc\nis2\ncnorm\nrmso\nsgr0" | tput -S' 2>&1 ) | grep -o '"\\[^"]*"' --color=always "\33]4;%p1%d;rgb:%p2%{255}%*%{1000}%/%2.2X/%p3%{255}%*%{1000}%/%2.2X/%p4%{255}%*%{1000}%/%2.2X\33\\\33[!p\33[?3;4l\33[4l\33>\33[?12l\33[?25h\33[27m\33(B\33[m" Lets say you want to find out what you need to echo in order to get the text to blink.. $ echo -e "`tput blink`This will blink`tput sgr0` This wont" Now you can use this function instead of calling tput (tput is much smarter for portable code because it works differently depending on the current TERM, and tput -T anyterm works too.) to turn that echo into a much faster executing code. tput queries files, opens files, etc.. but echo is very strait and narrow. So now you can do this: $ echo -e "\33[5mThis will blink\33(B\33[m This wont" More at http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html

Show a curses based menu selector
Not so much handy by itself, but very nice in shell scripts. This makes you a handy ncurses based checklist. Much like terminal installers, just use the arrow keys and hit 'Space' to adjust the selections. Returns all selected tags as strings, with no newline at the end. So, your output will be something like: "one" "two" "three" "four" "etc" For those who prefer bash expansion over gratuitious typing: $ whiptail --checklist "Simple checkbox menu" 12 35 3 $(echo {one,two,three,four}" '' 0"} ) Things to note: The height must includes the outer border and padding: add 7 to however many items you want to show up at the same time. If the status is 1, it will be selected by default. anything else, will be deselected.

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

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"

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }
