What is the benefit of using $() instead of backticks in shell scripts?

Question

There are two ways to capture the output of command line in bash:

1. Legacy Bourne shell backticks ``:

   var=`command`
            
   
   
           

Answer 1

This is a legacy question, but I came up with a perfectly valid example of $(...) over `...`.

I was using a remote desktop to windows running cygwin and wanted to iterate over a result of a command. Sadly, the backtick character was impossible to enter, either due to the remote desktop thing or cygwin itself.

It's sane to assume that a dollar sign and parentheses will be easier to type in such strange setups.
