Unix shell script to shorten URLs with tny.im URL shortener. wget must be installed for this to work.

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`

tny.im has shut down, as clearly indicated whenever one tries to visit any of the pages of the website.

Perhaps, this repo should be archived...
