In Bash scripting, we can split a string into substrings based on a delimiter using the built-in IFS - Internal Field Separator variable and the read command.
Let's take a look at an example.
Example 1:
#!/bin/bash
data_string="1,2,3,4,5,6,7,8,9,10"
delimiter=","
IFS="$delimiter"
read -ra str_array <<< "$data_string"
for element in "${str_array[@]}"; do
echo "$element"
done
Example 2: Delimiter as Pipe
#!/bin/bash
data_string="USA|UK|China|Japan|India|France"
IFS="|"
read -ra str_array <<< "$data_string"
for element in "${str_array[@]}"; do
echo "$element"
done
