Symbolic Linking

Command:

ln -s /original/file /new/link

This will create a link between the two files (or directories). Whatever you do: add, change or delete in one will happen in the other.

So, if you had a website in a dev directory in your home directory, ie ~/dev/websites/mynewwebsite, and Apache is installed and you want to view it through a brower, but you don't want to create a virtual host file and put an entry in the /etc/hosts file.

  1. The default "webroot" is at /var/www (check the documentation)

  2. You will need to do this as root (su - and enter password or prepend sudo to this command because the directory /var/www is owned by root):

    ln -s ~/dev/websites/mynewwebsite /var/www/mynewwebsite
    

You can now access the website through http://localhost/mynewwebsite

Git tab completion and prompt change

Git has a number of commands that you use on a regular basis and after a short while you remember them or you create aliases for them in the .bashrc or .bash_alias file and you remember them. Or maybe you don't.

Included in the source code for Git is a bash script called git-completion.bash.

I use this script for 2 things:1) to get tab completion of Git commands (hence the name) but it also provides a way to change the prompt and show that you are in a directory that has a Git repository in it and also what the current branch is.

We will do this in 2 steps. First the tab completion and then modifying the prompt.
