Bash: How to iterate over associative array and print all key/value pairs
The values of an associative array are accessed using the following syntax ${ARRAY[@]}.
To access the keys of an associative array in bash you need to use an exclamation point right before the name of the array: ${!ARRAY[@]}.
To iterate over the key/value pairs you can do something like the following example
# For every key in the associative array..
for KEY in "${!ARRAY[@]}"; do
# Print the KEY value
echo "Key: $KEY"
# Print the VALUE attached to that KEY
echo "Value: ${ARRAY[$KEY]}"
done
NOTE: The use of quotes around the array of keys ${!ARRAY[@]} in the for statement (plus the use of @ instead of *) is necessary in case any keys include spaces.
