问题
I wanted a hashmap equivalent in bash (keys as string and values as a list of integers). So, I wrote the following code-
declare -A PUBS
PUBS=( "FEE":"[345, 342]" "FOO":"[1, 2, 44]" "BAR":"[23, 67]" )
However, I get an error saying must use subscript when assigning associative array.
What's wrong here?
回答1:
You're not using the correct syntax to specify the keys. It's [key]=value, not key:value. So it should be:
PUBS=( ["FEE"]="[345, 342]" ["FOO"]="[1, 2, 44]" ["BAR"]="[23, 67]" )
