How to concatenate files?

To concatenate files in Linux 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.
• > redirects the output to a new file called combined.txt, which will contain the combined contents of file1.txt and file2.txt.

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

cat file1.txt file2.txt >> existingfile.txt

This will add the contents of file1.txt and file2.txt to the end of existingfile.txt without overwriting it.
