multiple commands assigned to bash variable


Hi,

Im tying to assign multiple commands to a variable and having
quite a hard time. Here's how it goes ..

$ pwd
/currentfolder

$ A="pwd"
$ $A
/currentfolder

$ pwd;pwd
/currentfolder
/currentfolder

$ A="pwd;pwd"
$ $A
-bash: pwd;pwd: command not found

Heh?! What am I missing here? spacing doesn't seem to help either.

Im running Ubuntu 6.06.1

Thanks in advance.

I'm not absolutely sure that you can do what you're wanting to do, in the way that you're wanting to do it... the ';' character is going to terminate the current command, and I don't think that you can pack that into a variable, and then unpack it correctly. (I can't quote chapter and verse from the bash man pages, so please take that with a large grain of salt)

What you can do, which is very similar, is create a shell function:

Code:
function A()
{
pwd
pwd
}
can be executed ...

Code:
$ A
/currentdirectory
/currentdirectory

that's a pretty nasty way of simplifying things... why aren't you using alias? that's exactly what it's for.

Yup! alias did the trick.

Thank you both for such quick relies.
