hi list, I was wondering how does a shell execute a "exec" command? just like any other command i guess....but i have a samll doubt on it's behaviour...... i did... $ exec man The shell closed! $ exec man & [1] 10618 $ What manual page do you want? [1]+ Exit 1 exec man $ The man page of exec says.... "If command is specified, it replaces the shell." But does'nt the shell "wait" for whatever command is given to it to complete???....little confused here. Moreover $ exec exit bash: exec: exit: not found did not work! is'nt "exit" also a command?
