The keys are accessed using an exclamation point: ${!array[@]}
, the values are accessed using ${array[@]}
.
You can iterate over the key/value pairs like this:
for i in "${!array[@]}"
do
echo "key : $i"
echo "value: ${array[$i]}"
done
Note the use of quotes around the variable in the for
statement (plus the use of @
instead of *
). This is necessary in case any keys include spaces.
The confusion in the other answer comes from the fact that your question includes "foo" and "bar" for both the keys and the values.
