Url link shortner Bash Script

tny

#!/bin/sh
if [ -t 0 ]; then
    if [ -z "$1" ]; then
      echo "usage: tny long_url [custom_keyword]"
      echo ""
      echo "Shorten URLs with tny.im URL shortener"
      echo "This script expects a long URL to shorten either as an argument or passed through STDIN."
      echo "When using arguments, an optional second argument can be provided to customize the later part of the short URL (keyword)."
      exit 1
    fi
    url=$1;
else
    while read -r line ; do
      url=$line
    done
fi 
echo `wget -q -O - http://tny.im/yourls-api.php?action=shorturl\&format=simple\&url=$url\&keyword=$2`

To install this as a standard Linux command, download the gist and rename it "tny". Then, on a shell, do the following:

cd # to the directory where you downloaded it

chmod +x tny
sudo mv tny /usr/bin

Now you can simply do

tny http://some-long-url.com

to shorten URLs from the shell.

As said on the script, you can also have a second parameter to create a custom short URL. Example:

tny http://some-long-url.com shorter

will return

http://tny.im/shorter

And you can use pipes redirection too:

echo http://some-long-url.com | tny

Enjoy!
