Can you give examples of builtins?

Sure! Here are some common examples of shell builtins:

1. cd: Changes the current directory.

   cd /path/to/directory
   

2. echo: Displays a line of text or variable value.

   echo "Hello, World!"
   

3. export: Sets environment variables.

   export MY_VAR="value"
   

4. alias: Creates shortcuts for commands.

   alias ll='ls -la'
   

5. history: Displays the command history.

   history
   

6. exit: Exits the shell or script.

   exit
   

These builtins are integral to shell operation and do not require separate executable files. If you need more information or examples, let me know!
