begin end or brackets for bash?

I was trying to do some bash programming and wanted to make it somewhat structural. My questions is if I want to make a block code embedded in a bracket like the Pascal begin & end or the C {}, just to put a logically atomic group of commands together, is there a way in BASH to do it.

I can think of using a vacuous conditional or loop, but it's kind of ugly.

Thanks

Note that bash blocks aren't "atomic" in any particular sense. See the bash manual page (i.e. run man bash if on a unix system), or look it up online:

http://www.gnu.org/software/bash/manual/bashref.html

You should start in section 3.2.4, Compound Commands.

Bash doesn't really have variable scoping, so besides flow control, I don't think you will achieve much. Why not use some functions?

Bash supports braces.

{
  cmd1
  cmd2
}

Note that there must be a command separator before the closing brace.

{ cmd1 ; cmd2 ; }
