What caused you to believe that would work? > This produces an error: > $ declare -A array; unset array[@]; array[path/directory]=value > bash: path/directory: division by 0 (error token is "directory") unset 'array[@]' appears to be exactly the same as unset 'array'. It completely eradicates the entire array, including the declaration that it is associative. Then when you do array[a/b]=c you are creating a new integer-indexed array. [a/b] becomes a math context, so it tries to divide the value of a by the value of b (using 0 if either of those is not set). On that note, today I learned that you are not allowed to use either * or @ as the index of an associative array in bash. I guess I can see why, but... that's probably going to break something some day.
