Could you please share the shell script for learn

[jeesshnasree]

Hi all ,

could you please guide me for learn bash Linux shell script.

Actually I need to learn all bash shell script concepts with detailed description and syntax with examples. If possible could you please share .

[Lisenet]

The way I learnt bash was by reading the man page and starting to code. Bash compound commands (for, case, if, while etc), conditional expressions, shell builtin commands (break, continue, getopts, popd, pushd, read etc), exit status codes and much more:

$ man bash

 There are examples too!

Hi @Lisenet,

 thanks for share but how to learn use by man <command> .

i think man <command> only shows usage arguments with command.

but start from initial stage to write programs/jobs/automation scripts .

if possible any video tutorial or kindly share book or blog for learn shell script.

Thanks

Well, this is how you start from the initial stage, you read about bash. Unless you use another shell, then in most cases "shell scripts" are written in bash. The man page has a lot of information.

As mentioned above, your best bet for learning initially is to just start scripting. Find very basic things you can script/automate, then just keep making them better and better. Never quit trying to make your script more functional, or better written.

When you have the basics down, I really recommend this cheatsheet for reference, and the Bash Hacker's Wiki
