Bash while Loop to Iterate through 2 Files Reading two or more files is an important task to compare two files and process data. In the following example, it will be achieved using Bash while loop. #!/bin/bash line_number=1 while IFS= read -r lineA <&3 && IFS= read -r lineB <...
The loop constructs are common programming building blocks that allow us to repeat the execution of a section of code through an iteration. The four main types of iteration constructs are the count-controlled loops (or definite iteration), the condition-controlled loops (or indefinite iteration), ...
