Will unix and shell programming help in any ways for web application developer?

Question

I recently came across this book, UNIX & shell programming by forouzan and gilberg, in the past many told to hv command over this topic, but I am not getting clear picture how it will help, ( I m not new to Unix , my os is Ubuntu, and I am aware of many commands and operate tools like vim and git frequently through command line.)
But will it help in web applications development, is yes then which areas to focus

Answer 1

I know git more than 1ooo commits for me, but shell programming in general I m asking, I need specific implementation examples for it ,

Answer 2

Well, are you interested in it? If you only do web development you will probably never need it, but if you want to, remember: Knowledge is power.

Answer 3

hmmm, I was looking for a reason to learn it, I can't learn new tools without a reason

Answer 4

If you like IDE's keep using them. But seriously, learn Git. Git is the single most important thing you will always love later.

Answer 5

You can use bash to create a shell script which will perform specific tasks sparing you the efforts to type the commands over and over again. 
There are other similar shells like ksh,zsh,sh,csh and so on. You can use any of them in your system.
