curl -q -s http://www.hasthelhcdestroyedtheearth.com/ | sed -En '/span/s/.*>(.*)<.*/\1/p'

User: Tatsh

Use -q as first argument (as described in `man curl`) to ignore curlrc to ensure the output is always the same regardless of user's configuration.

This says if the LHC has destroyed the world. Run it in a loop to monitor the state of Earth. Might not work reliable, if the world has actually been destroyed.

btc() { echo "1 BTC = $(curl -s https://api.coindesk.com/v1/bpi/currentprice/$1.json | jq .bpi.\"$1\".rate | tr -d \"\"\") $1"; }

Functions: echo

The only pre-requisite is jq (and curl, obviously).

The other version used grep, but jq is much more suited to JSON parsing than that.

sh <(curl hashbang.sh)
2015-03-15 21:02:01
User: lrvick
Functions: sh

Bash process substitution which curls the website 'hashbang.sh' and executes the shell script embedded in the page.

This is obviously not the most secure way to run something like this, and we will scold you if you try.

The smarter way would be:

Download locally over SSL

> curl https://hashbang.sh >> hashbang.sh

Verify integrty with GPG (If available)

> gpg --recv-keys 0xD2C4C74D8FAA96F5

> gpg --verify hashbang.sh

Inspect source code

> less hashbang.sh


> chmod +x hashbang.sh

> ./hashbang.sh

User: adria

http://ifconfig.me is a web site which shows your public iP address.

If you want use your own code, you can use PHP code such as:

function getip()


return "".$_SERVER["REMOTE_ADDR"];


echo getip();


Then, you'll get your IP by 'curl yourfile.php'.

User: cbuckley
Functions: sed
Tags: curl http

Similar to the following:

curl -I <URL>

but curl -I performs a HEAD request, which can yield different results.

curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"GUI.ShowNotification","params":{"title":"This is the title of the message","message":"This is the body of the message"},"id":1}' http://i3c.pla.lcl:8080/jsonrpc

This encodes it in ogg format.

Does on-the-fly encoding of the incoming stream.

Great for radio streams as they're often flv format.

2013-07-12 07:43:21
User: nixnax
Functions: link

Use the command line to log into Dropbox. You have to replace me@yahoo.com with your Dropbox email (note the URL-encoding of "@" as %40). Also replace my_passwd with your Dropbox password. (Note: special characters in your password (such as #) must be url-encoded. You will get a cookie (stored in file "cookie") that you can use for subsequent curl operations to dropbox, for example curl -b cookie https://www.dropbox.com/home. Debug note: If you want to see what data curl posts, use curl's --trace-ascii flag.
