In sh/bash, the variable $? holds the exit value of the last command to run.
So you
can do:

mount ....
if [$? -ne 0]
then
echo "command failed"
... more stuff ...
fi

"man bash" and "man test" for more information.

For extracting the date in the format you like, try:

date '+%Y%m%d'

"man date" for more information.

And there are loads of online tutorials on shell scripting. Google turned up
one such
tutorial for me:

There must be others too.
