Empty a file

Bash Script Beautifier

Today I was working on a bash script written by someone else. And the script was maintained since long and had actually become quite big and there was no indentation followed. So, you can understand how difficult it was to understand the script. So, I set my foot forth to first find a beautifier for the bash script before I fixed it and my search ended here.

Building a Finite State Machine Using DFA::Simple By Bill Ruppert on September 23, 2004 12:00 AM I am converting some articles from MS Word to HTML by hand. I often use bulleted outlines so I face a lot of work creating lists with nested sub-lists. It didn’t take opening and closing many

and

• tags to realize I wanted to automate the task. It’s very easy to use filters with my text editor and I’ve written several in Perl to speed up my HTML formatting. I decided to create a filter to handle this annoying chore. After a little thought I decided the logic involved was just tricky enough to use a finite state machine (FSM) to keep things straight.
