Summary 0001442: Improvement to getopts example, remove double negation
Description On getopts's page
https://pubs.opengroup.org/onlinepubs/9699919799/utilities/getopts.html [^]
The example uses interesting double negation in the two tests:
if [ ! -z "$aflag" ]; then
if [ ! -z "$bflag" ]; then
! -z could be shortened to -n
Desired Action Replace
if [ ! -z "$aflag" ]; then
with
if [ -n "$aflag" ]; then
and
if [ ! -z "$bflag" ]; then
with
if [ -n "$bflag" ]; then
Tags No tags attached.
