| [[Anchor(faq82)]] == Why is $(...) preferred over `...` (backticks)? == For several reasons: * It makes nesting command substitutions easier. Compare: {{{ x=$(grep $(dirname "$path") file) x=`grep \`dirname "$path"\` file`}}} It just gets uglier and uglier after two levels. * It's easier to read. * Newbies who see {{{$()}}} don't normally press the wrong keys. On the other hand, newbies who see {{{`cmd`}}} often mangle it into {{{'cmd'}}} because they don't know what a backtick is. * Backslashes (\) inside backticks are handled in a non-obvious manner. ''(Example desired!)'' Inside {{{$()}}}, there are no such surprises. The only time backticks are preferred is when writing code for the oldest Bourne shells, which do not know about {{{$()}}}. |
