Details:
Since find already has the GNU extension ',' operator (evaluate both
expressions, without short-circuiting based on the first), it might be useful
to have a GNU extension ? : operator (evaluate the first expression, which
determines which of the other two expressions will be evaluated), with
precedence below -o but above ','.
As an example usage pattern:
$ find . -type l \? \( -exec echo {} 'links to ' \; , -exec readlink {} \; \)
: -exec echo {} not a link \;
This capability is just syntax sugar; the above proposed command line can be
mimicked by the longer:
$ find . \( -type l \( -exec echo {} 'links to ' \; , -exec readlink {} \; ,
-true \) \) -o -exec echo {} not a link \;
