I'd use grep
Code:
$ echo "12/31/2004" | grep '^[0-1][0-9]/[0-3][0-9]/[0-9]\{4\}$' >/dev/null 2>&1
$ echo $?
0
$ echo "some text" | grep '^[0-1][0-9]/[0-3][0-9]/[0-9]\{4\}$' >/dev/null 2>&1
$ echo $?
1

You can then check $? and act accordingly.

You can extend this example to simple numerical verification...
Code:
$ echo "193912391293" | grep '^[0-9]*$'

You get the idea....

Cheers
