Conditionals in BASH

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The conditionals && and || in bash are short-circuit, so that once a
term is evaluated that determines the success or failure of the entire
expression, evaluation of the remaining alternatives is skipped.

In a test expression (enclosed in [ ... ]), are the conditionals -a and
-o also short-circuit?  The O'Reilly BASH book seems to suggest that
they are not, but the description seems to me to be ambiguous.

TIA.
