What are other built-in commands?

Here are some common built-in commands in Linux:

1. cd: Change the current directory.
2. echo: Display a line of text or a variable value.
3. exit: Exit the shell or terminate a script.
4. pwd: Print the current working directory.
5. history: Display the command history.
6. alias: Create an alias for a command.
7. unset: Remove a variable or function.
8. export: Set environment variables.
9. set: Set shell options and positional parameters.
10. fg: Bring a background job to the foreground.

These commands are executed directly by the shell and do not require external programs.
