Good day -
Please could anyone explain why the first command below produces no output:
$ ( declare -A a=([a]=1); if [ -v a ]; then echo yes; fi )
$ ( declare -a a=([0]=1); if [ -v a ]; then echo yes; fi )
yes
$
There does not appear to be any documentation about
different behaviour of -v for associative vs. normal arrays:
-v varname
True if the shell variable varname is set (has been
assigned a value).
Should that be ammended to :
-v varname
True if the shell variable varname is not an associative
array and is set
(has been assigned a value).
or is this a bug with -v ?
I'm using bash-4.3.30(1) , but it appears also to be an issue with
bash-4.3.11(1) .
Regards,
Jason
