I am interested in learning shell script ompletely. Can anyone suggest some good online resources?
The best free source for shell scripting I've seen so far: http://fog.ccsf.cc.ca.us/~gboyd/cs160b/online/index.html
You can check out this site: Writing Shell Scripts. Things have been explained in a very simple language, and the flow is quite good.
There is an upcoming blog about unix and shell. The commands are explained in simple manner. You can try it:
It is probably worth you while reading the man page for bash (type
man bash at your prompt) as it covers quite a lot of useful information in a concise manner. Also look at some of the other
man pages such as
test (used with
if... while... statments),
sed. You will find other tutorials probably easier or more useful to read as a beginner, but you will definitely come back to the
man pages regularly so it helps to get to know them.
My Ubuntu shell has a program called
vimtutor which looks useful for learning vi.
