Using bash to get some data from the files can be very useful. Here are some essential tricks to get you started.

1. See if the file has a word called “hello”:

cat file.txt |grep hello

2. Compare two files using cmp / cmp is usually part of the diffutils package.

This part is best done with simple script. However, scripting is not mandatory when using cmp.

#!/bin/bash

# Creating two new files with: echo "Helllo" > file.txt && echo "Hello" > file2.txt

file1="file.txt"
file2="file2.txt"

if cmp "$file1" "$file2"; then
echo "Files are the same."
else
echo "Files are not the same."
