Answer Posted / ganesh
When you ask a shell to execute the command $ date, the
shell uses the system call exec to
ask the UNIX kernel to execute the command you requested.
The shell passes the name of the command that should be
executed to the exec system call.
This system call reads the first two characters in a file to
determine how to execute the command.
In the case of shell scripts, the first two characters are
#!, indicating that the script needs to be interpreted by
another program instead of executed directly.
The rest of the line is treated as the name of the
interpreter to use.
Usually the interpreter is /bin/sh, but you can also specify
options to the shell on this line
