Shell scripting is part of my day today life job. Sometime you just need to cut or grab first few characters of a string. For example, consider following string I am using in a script:
I just need to grab network id i.e. 192.168.1 of a string $IP
I can write out
$ echo $test
It took me more than an hour to find out solution to this tiny problem. BASH man page Parameter Expansion has lots of information. Make sure you read it.Tweet itFacebook itGoogle+ itPDF itFound an error/typo on this page?
