Bash How to Echo Array
You can define three elements array (there is no space between the name of an array variable, equal symbol, and starting bracket):
FILES=(report.jpg status.txt scan.jpg)
This command will write each element in the array:
echo ${FILES[*]}
Index in shell arrays starts from 0. So, if you want to write just the first element, you can do this command:
echo ${FILES[0]}
Output: report.jpg
Do you want to process each element in the array in the loop? Here is an example:
for ELEMENT in ${FILES[@]}
do
echo File: $ELEMENT.
done
If you want to get only indexes of the array, try this example:
echo ${!FILES[@]}
“${!FILES[@]}” is a relatively new bash feature, it was not included in the original array implementation.
