True, but if you just want to test another shell, or test
writing a script in bash but you usually use tcsh, you 
just
type the name of the shell (like 'sh' or 'csh') from the
command line. It will fork off a "subshell", which is
another process *in addition to* the current shell, whereas
'exec' *replaces* the current shell in situ; so running
the subshell is just like running any other process like
a text editor.

While the brown ale he quaffed,
Loud then the champion laughed,
And as the wind-gusts waft
The sea-foam brightly,
So the loud laugh of scorn,
Out of those lips unshorn,
From the deep drinking-horn
Blew the foam lightly. --Longfellow
