This is a short tutorial explaining how to post to Twitter using command-line in Linux, without needing to even open up your web browser.

First, install the curl package:

sudo apt-get install curl

Next, create a script anywhere in your $PATH, for example twitter.sh inside ~/bin, where ~ is your home directory (make sure ~/bin is included in your $PATHvariable, in case echo $PATH doesn't return it, edit~/.bashrc and add a line like this: export PATH=/home/USER/bin/:$PATH).

The script twitter.sh should contain the following:

#!/bin/bash
curl -u USERASS -d status="$*" http://twitter.com/statuses/update.xml > /dev/null
echo "Message sent!"

Replace USER and PASS with your Twitter username and password, and then make the script executable:

chmod 755 ~/bin/twitter.sh

And now test it:

twitter.sh Hello, world! This is a test.

So just use it as:

twitter.sh YOUR MESSAGE
