我有一个循环变量名称，我需要检查该名称指向的变量是否是一个数组。我试图google，但什么也找不到。任何帮助？
for varname in AA BB CC; do
local val
if [ "$varname" is array ]; then # how can I perform this test?
echo do something with an array
else
echo do something with a "'normal'" variable
fi
done
Google可能是
your friend：
declare -p variable-name 2> /dev/null | grep -q '^declare \-a'
