But of course, you don’t want to be typing all that every time you want to update your twitter status. So I found this website which has a executable twitter bash script.

Replace the user and password with your twitter user id and password. Now save the text to a file called ‘twitter‘ and give the file execute permission. Put this file in any folder in your path. If you want to use this script everywhere on the server make sure it’s located in /usr/local/bin or ~/bin. If you are a user on the server, you may just create the file in your ~/user folder.

Now, how to use the script?

If you have created the twitter file in /usr/local/bin or ~/bin you may use this command anywhere you are in the server.

For best results, enclose the message within quotes. This will prevent problems when using wild card characters like ‘?’

And if have created the twitter file in your ~/user directory, make sure you are in the same folder as the file and then you may use this command.

Not working?

Did you make sure the file has executable rights?

You can check your server using the following command if you have already installed it or not.

If nothing shows up, install the package unrar. If you are using a Linux OS which uses yum update you can use the following command to install it.

If that does not work for you, you can simply install it manually using the next commands.

When that is all done, we can start using unrar. If you want to unrar multiple .rar files at once, you may use this command.

For example:

Output:

This example search for anything above 50MB.

This example search for anything above 100MB.

This example search for anything above 1000MB.

Modify your search changing the digit between the “+” and “M”.. Make sense right?
