Bash Read a file (data stream, variable) line-by-line (and/or field-by-field)? Read a string field by field
Example
Let's assume that the field separator is :
var='line: 1
line: 2
line3'
while IFS= read -d : -r field || [ -n "$field" ]; do
echo "-$field-"
done <<< "$var"
Output:
-line-
- 1
line-
- 2
line3
-
