First, install the curl package:

sudo apt-get install curl

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

The script tweet.sh should contain the following:

#!/bin/sh

############EDIT THE FOLLOWING LINES...###########################
user="USERNAME"
pass="PASSWORD"
##################################################################

######################DO NOT EDIT BELOW THIS######################
tweet="${@}"

if [ $(echo "${tweet}" | wc -c) -gt 140 ]; then
    echo "FATAL: The tweet is longer than 140 characters!"
    exit 1
fi

curl -k -u ${user}:${pass} -d status="${tweet}" https://twitter.com/statuses/update.xml >/dev/null 2>&1

if [ "$?" == "0" ]; then
    echo "Successful tweet!"
fi

Replace USERNAME and PASSWORD with your Twitter username and password, and then make the script executable:

chmod 755 ~/bin/tweet.sh

And now test it.. Just use it as :

tweet.sh YOUR MESSAGE

This should be all…

If you don’t want to copy paste the code for tweet.sh then use the following link to download tweet.txt and RENAME it as tweet.sh

Many times I observed, that Linux sysadmin beginners remember remember well how to move among the commands by pressing up and down arrows. They also remember how to use Tab in the command line for completion. Yet, somehow they forget that a great bash command history will pull out the complete history list of commands that they used.

Naturally, getting to see the whole list of commands might not come handy. It is much better, for example, to go back to the last 10 commands and type in the terminal history 10. This will do the trick.

There are so many other built-in bash history commands that it will take hefty hundred pages to describe them all. I just want to mention another useful history manipulation command that is called simply fc. This one is very valuable becaue it allow you to open vi editor and run the command after editing it to your liking. For example, fc 356 will allow you to edit this command in vi and then immediately invoke it for you.

Cheers..
