BASH: Calling method for each entry of string array

[fritzbender]

Hi there,

I saw that functions have been called several times in BASH using brackets. I wanted to do the same thing, so calling my function my_func three times and passing another entry of the string array each time:

my_func() {
  do_something_with $1
}
my_func { "a" "b" "c"}

but the method is only called once. What am I doing wrong? Did I misunderstood the bracket pattern? Don't get me wrong, I know how to create and pass an array in BASH I just wanted to use that new pattern.

Thanks

my_func() {
    echo Working on $1...
}
a=(one two three)
for v in ${a[@]} ; do my_func $v ; done

Could you give us an example of where you've seen that ? I've written and read shell scripts for quite some time and never came across something like you describe. There's also no mention of any capability like that in the manual that I can find.

Ah, I found it. It's called the brace expression and can be used like this:

echo Front-{A,B,C}-Back

which results in: Front-A-Back Front-B-Back Front-C-Back

Sorry for my confusing question.
