Using bash to get some data from the files can be very useful. Here are some essential tricks to get you started.
- See if the file has a word called “hello”:
cat file.txt |grep hello
- 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."
