One of theneat things a user can do on Unix is play around with the Bourne Again Shell (bash). An even more interesting thing is how the environment can be tweaked to a particular user's preference. In this text a look at how the Bash prompt can be manipulated by inserting commands and even shell code functions directly into the prompt itself.
A Sample Function inline with Bashprompt
In a recent text configuring colors for the Bash prompt was discussed. In this text a method of messing with the prompt is expanded upon by actually inserting a shell code function inline with the bash prompt.
A Basic Bash Prompt
The bash prompt has built in commands that use escape charachter syntax. By default a lot of packages ship bash with a default that shows the hostname and relative path. The escape sequences for all users is usually kept in /etc/bashrc or a similar system location.
I love stuff like this. I think anyone wanting to learn to write programs should start with a good deep dive into Bash. You can do an amazing lot of things with plain ole Bash guff!
