cat: Append several files to an output file.
$ cat ${filename1 filename2 ---} >> ${path-to-output_file}
try on your machine

This command is using the cat command in a Linux or Unix-like operating system. Here's a breakdown of the components:

  1. cat: It is a command-line utility that concatenates and displays the contents of files. In this case, it will concatenate the contents of filename1, filename2, and any other files provided.

  2. ${filename1 filename2 ---}: This is a placeholder, indicating that you should replace it with the actual filenames you want to concatenate. You can specify multiple filenames separated by spaces.

  3. : It is a redirect operator used to append the output of a command to an existing file (or create a new one if it doesn't exist).

  4. ${path-to-output_file}: This is another placeholder that should be replaced with the desired path and filename for the output file. The output of the cat command will be appended to this file.

So, when you execute this command in a terminal, it will concatenate the contents of filename1, filename2, and any other specified files, and append the combined content to the specified output file.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
