examples of using basic linux regular expressions

linux regular expressions

Linux regular expressions are very much useful, when working with extracting text from files, sorting output from command results, scripting some task etc. I believe regular expressions are bit difficult to master as, they can be used in myriad number of ways. Some of the expressions are deprecated, while some are still kept for backward compatibility.

we will go through some of the most used and very useful way of working with regular expressions here. Let me make one thing very clear, that regular expressions in linux and any programming language is a very large topic in itself, that its beyond the scope of this blog post to cover it completely.

Comments, suggestions are always welcome.
