Package: bash
Version: 3.0-14
Severity: wishlist
Tags: patch
See proposed patch. It is more robust to use && than "-a".
$ echo 1 > t.tmp
$ set -x
See difference between these two:
$ [ ! -r t.tmp ] && [ "$(cat t.tmp)" ]
$ [ ! -r t.tmp -a "$(cat t.tmp)" ]
Results:
+ '[' '!' -r t.tmp ']' (a)
++ cat t.tmp
+ '[' '!' -r t.tmp -a 1 ']' (b)
The "-a" causes running all commands regardless of the left hand;
on the other hand "&&" always short circuits.
