+# Splitting input into an array
+
+## `readarray`
+
+`readarray` makes it really easy to split input into an array.
+
+Say we have this file as input:
+
+```
+123
+456
+789
+```
+
+Then we can split like so:
+
+```bash
+readarray -t name_for_array < ./input.text
+
+# Print all elements
+echo "${name_for_array[@]}"
+
+# Print element by index
+
+echo "${name_for_array[1]}"
+456
+```
+
+If we want to read direct from string within bash file:
+
+```bash
+readarray -t new_name_for_array <<< "here
+is
+some
+text"
+
+echo "${new_name_for_array[1]}"
+is
+```
+
+> The _-t_ flag removes the trailing newline
