Hi,
exec can be used for two cases. One is to replace the shell with a
given program.
http://wiki.bash-hackers.org/commands/builtin/exec
But it is not clear to me beside making wrappers, whether are other
important use cases of which exec is useful.
According to this, it seems that this usage of exec is not very useful
nowadays unless one is on a computer with limited resources. Is it so?
