What are the functions of the cat command in Linux?

The main functions of the ‘cat’ command in Linux include:

1. Display file content: Output the content of the file to the terminal.
2. Creating files: When using the cat command, if the specified file does not exist, the cat command will create a new file.
3. Merge files: You can combine the content of multiple files into one file.
4. Additional file content: You can append new content to the end of an existing file.
5. Copy files: This allows for the content of one file to be duplicated into another file.
6. Redirect: content of a file can be redirected to standard output, standard error, or other files.
7. View file properties: You can check the permissions, owner, size, and other property details of the file.

In general, the cat command is primarily used to display file contents, create, merge, copy files, and redirect file contents.
