How to merge more than two files?

That's a very practical question, and it directly builds on what we just discussed about concatenating!

If you want to merge more than two files, the process is exactly the same: you just list all the files you want to combine after the cat command, in the order you want their contents to appear in the merged file, and then redirect the output to a new file.

Here's the general syntax for merging multiple files:

cat file1 file2 file3 ... fileN > merged_output_file

Let's illustrate with an example:

Imagine you have three files:

part1.txt contains:
```
This is
```
part2.txt contains:
```
the first
```
part3.txt contains:
```
sentence.
```

To merge all three into a single file named full_sentence.txt, you would run:

cat part1.txt part2.txt part3.txt > full_sentence.txt

After running this command, full_sentence.txt would contain:

This is
the first
sentence.

Remember, just like with two files, if full_sentence.txt did not exist, cat would create it. If it did exist, > would overwrite its existing content. If you wanted to add to an existing file, you'd use >> instead.

Do you have particular files in mind you'd like to try merging? We can create some temporary files right here in your LabEx VM to practice!
