Bash: Iterate through $@ (easy++)

beatnik007 · 04-03-2004, 01:01 AM

Excuse me for being such a newbie but, well this is the place for it right?

I've been reading the bash manpage, but can't make sense of the definition of "list". As such I don't understand how to iterate through the input parameters. I've tried variations on the following:

Code:

for param in $@ do {
    echo $param;
}

But nothing seems to be syntactically correct.

As an aside, is there a good site for beginners bash?

Thanks

Try

#!/bin/bash
# first let it know which shell you're using.

for param in $@
do
{
echo $param;
}
done

You need the 'done' to 'close off' the 'do'. Putting the 'do' on a different line from the 'if' means that you don't have to put a ';' after the '$@', there are lots of these little things to learn.
2: type "bash tutorial" into google, there are lots of them.
