How to concatenate files with cat?

To concatenate files using the cat command, you can use the following syntax:

cat file1.txt file2.txt > combined.txt

In this example:

• file1.txt and file2.txt are the files you want to concatenate.
• The > operator redirects the output to a new file called combined.txt, which will contain the contents of both file1.txt and file2.txt.

If you want to append the contents of additional files to an existing file, you can use the >> operator:

cat file3.txt >> combined.txt

This command will add the contents of file3.txt to the end of combined.txt without overwriting it.
