Answer / ashu
The exec command will execute a command in place of the
current shell; that is, it terminates the current shell and
starts a new process in its place.
Use of exec command:
exec is oftenly used to execute the last command of a shell
script. This would kill the shell slightly earlier;
otherwise, the shell would wait until the last command was
finished. This practice saved a process and some memory.
