Now I want to know how the internal(built in) commands are executed.

lastcomm
lastcomm(1) General Commands Manual lastcomm(1)Name
lastcomm - show last commands executed in reverse order
Syntax
lastcomm [command name...] [user name...] [terminal name...]
Description
The command gives information on previously executed commands. With no arguments, prints information about all the commands recorded dur-
ing the current accounting file's lifetime. If called with arguments, only accounting entries with a matching command name, user name, or
terminal name are printed. The following example produces a listing of all the executions of commands named by user root on the terminal
ttyd0:
lastcomm a.out root ttyd0
For each process entry, the following are printed:
The name of the user who ran the process.
Flags, as accumulated by the accounting facilities in the system.
The command name under which the process was called.
The amount of cpu time used by the process (in seconds).
The time the process exited.
The flags are encoded as follows:
``S'' indicates the command was executed by the super-user
``F'' indicates the command ran after a fork, but without a following exec
``C'' indicates the command was run in PDP-11 compatibility mode (VAX only)
``D'' indicates the command terminated with the generation of a core file
``X'' indicates the command was terminated with the signal SIGTERM
