ProgrammingThis forum is for all programming questions.
The question does not have to be directly related to Linux and any language is fair game.

Bash, the shell has its own language, yes. Most (all?) shells have their own language, or use the language of another shell. As far as what is it based on, I don't know to be honest.

Rep:
You are yet to discover the power of *nix. Bash is a shell accepting commands. Every command you issue you can put in a shell script and execute it. (Just like dos.bat files)
But the other way around, you can use any command from a script in your shell. Say you enter this in your console:
Code:
function foo{
echo $1
}
That looks purely like a program, doesn't it? Enter it on your command line.

What was the first instance of using a word command to control a computer? (Not counting things like assembler.)
Okay, well clearly no one knows and it's not as if I have any 'guru' rep to lose, so what's the answer?
BTW, I am now up to page 200 of the Bash Shell-Scripting Bible (Wiley) and nowhere yet can I find anything to state that Bash is anything other than one of a number of shells. Not calling you guys liars of course - I'm happy to accept it's a language as well - but just just excusing my ignorance. ;-)

A shell consists of two parts, the command interpreter and the part which forks and executes a program.
The command interpreter is an interpreter (duh!) and the language it interpretes is the Bash scripting language. Although it may sound strange given the sometimes crooked syntax constructs, there exists a formal language description for the Bash language.
