programming knowledge java youtube Shell Scripting Tutorial for Beginners 17 - Read a file content in Bash

How do I read a text file line by line under a Linux or UNIX-like system using BASH shell?
You can use while..do..done bash loop to read file line by line on a Linux, OSX, or Unix-like system.
There are basically three ways to read file content using bash.
1a: While loop: Single line at a time: Input redirection.
1b: While loop: Single line at a time:
Open the file, read from a file descriptor (in this case file descriptor #4).
2: While loop: Read file into single variable and parse.
