To join two or more text files on the Linux command-line, you can use the cat command. The cat (short for “concatenate”) command is one of the most commonly used commands in Linux as well as other UNIX-like operating systems, used to concatenate files and print on the standard output.
If your system uses GNU tar , you can use tar in conjunction with the gzip file compression utility to combine multiple files into a compressed archive file.
