On: Why do long options start with two dashes? (2019)

[kazinator]

I'd like a word with the person who thought that regular ( ) parentheses for grouping were a good idea in the find syntax, requiring them to be backslash-escaped in shell scripts.

The obviously right choice would have been [ ]. You know, like in

   if [ $foo ... ]

[spc476 → kazinator]

That won't work because '[' is an alias for test.

[jlokier → spc476]

"[" as an argument to another command is fine.

"[" is just another name for the "test" command. It isn't special syntax.
