  • Just add this function to your .zshrc / .bashrc, and by typing "shout *URL*" you get a randomly chosen English word that uses to short your URL. You may now go to*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

    shout () { curl -s "$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

    qrurl() { curl -sS "|0&chl=$1" -o - | display -filter point -resize 600x600 png:-; }

  • That makes a function you can put in your ~/.bashrc to run it when you need in any term with an IP as argument Show Sample Output

    GeoipLookUp(){ curl -A "Mozilla/5.0" -s "$1" | grep "^IP.*$1" | html2text; }

  • use curl and sed to shorten an url via

    curl -s ''"$1" | sed -e 's/{"short_url":"//' -e 's/"}/\n/g'

  • runs an rss feed through sed replacing the closing tags with newlines and the opening tags with white space making it readable. Show Sample Output

    curl --silent "FEED ADDRESS" |sed -e 's/<\/[^>]*>/\n/g' -e 's/<[^>]*>//g
    ljmhk · 2011-04-11 14:08:50 2
  • 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

    curl -u username --silent "" | 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'

  • required packages: curl, xml2, html2text command is truncated, see 'sample output' Show Sample Output

    open R,"curl -s|xml2|"; while(<R>){ chomp; m(^/rss/channel/item/title=) and do{ s/^.*?=//; ($t,$d,$l)=($_,undef,undef) }; m(^/rss/channel/item/description=) and do{ s/^.*?=//; push @d,$_ }; m(^/rss/channel/item

  • Watches the headers of a curl, following any redirects and printing only the HTTP status and the location of the possible redirects. Show Sample Output

    watch 'curl -s --location -I | grep -e "\(HTTP\|Location\)"'

  • 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$IP -I -s; done

    curl --resolve -I -s

  • miss a class at UTOSC2010? need a refresher? use this to curl down all the presentations from the UTOSC website. ( NOTE/WARNING this will dump them in the current directory and there are around 37 and some are big - tested on OSX10.6.1 Show Sample Output

    b=""; for p in $( curl -s $b/presentation/schedule/ | grep /presentation/[0-9]*/ | cut -d"\"" -f2 ); do f=$(curl -s $b$p | grep "/static/slides/" | cut -d"\"" -f4); if [ -n "$f" ]; then echo $b$f; curl -O $b$f; fi done

  • 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

    curl -fs 2&>1 > /dev/null || echo ping failed | mail -ne -s'Server unavailable'
    mccalni · 2009-10-23 14:29:06 1
  • A function that takes a domain name as an argument Show Sample Output

    geo(){ curl -s "$(dig +short $1)"| sed '/^IP:/!d;s/<[^>][^>]*>//g'; }

  • Requires display. Corrected version thanks to sputnick and eightmillion user.

    display$(curl -s|grep -Po '"\K/dyn/str_strip(/0+){4}/.*strip.[^\.]*\.gif')

  • 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

    curl -s$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)}'

  • 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

    curl -s | grep 'id="user_' | grep -o '[0-9]*'
    spiffwalker · 2010-04-04 18:43:14 7
  • 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 &

    url="[Youtube URL]"; echo $(curl ${url%&*} 2>&1 | grep -iA2 '<title>' | grep '-') | sed 's/^- //'

  • 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 Show Sample Output

    rkulla · 2010-05-30 00:18:00 2
  • 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'.

What's this? 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.

Optimal way of deleting huge numbers of files
This command works by rsyncing the target directory (containing the files you want to delete) with an empty directory. The '--delete' switch instructs rsync to remove files that are not present in the source directory. Since there are no files there, all the files will be deleted. I'm not clear on why it's faster than 'find -delete', but it is. Benchmarks here:

Get Your IP Geographic Location with curl and jq

When was your OS installed?
shows also time if its the same year or shows year if installed before actual year and also works if /etc is a link (mac os)

Get IP from hostname
Get the IP of a hostname.

Enable ** to expand files recursively (>=bash-4.0)
Since bash 4.0, you can use ** to recursively expand to all files in the current directory. This behaviour is disabled by default, this command enables it (you'd best put it in your .profile). See the sample output for clarification. In my opinion this is much better than creating hacks with find and xargs when you want to pass files to an application.

Equivalent to ifconfig -a in HPUX
Command is properly working on HP-UX 11.31

floating point operations in shell scripts
using bc is for sissies. dc is much better :-D Polish notation will rule the world...

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.
