Write Practical Shell Scripts

See the original posting on DZone Python

In the last post, we talked about regex, and see how to use them in sed and awk for text processing. Additionally, we discussed Linux sed commands and awk commands. During the series, we’ve written small shell scripts, but we didn’t mix things up. I think we should take a small step and write a shell script that can be somewhat useful.

The main reason for learning to write a shell script is to be able to create your own Linux utilities. Understanding how to write useful and practical scripts is important. Sometimes, however, it helps to do something fun to learn a concept or skill. The scripts in this post can be lots of fun! And they help empower the concepts behind the script.
