Sorry to see nobody answer you but you do not need a script to see if your SD card is plugged in or not because it is already built in to the OS.
Are you having problems seeing the sd card?.

You use the browser in your device to see it is there or not also you can use your pc browser to see it and write or mount whatever you want.
You need to be more specific to what problem your having.

I want to make script that does "something" when the sd card is plugged in, and another "thing" when it isn't plugged in.
For that to work, I need to implement a code in the script that checks if the memory card is in or not, to see what "thing" it shall do.

The list of what's mounted is /etc/mtab, and the mmc is /dev/mmcblk1p1.
So something like
Edited to explain:
First line sets the variable $TEST with the output of the command that's in backticks. The grep command searches for the mmcblk1p1 in the list of what's currently mounted, the -o switch says output only what matched.
Then, in shell, if that gets us a non zero length response, well, we found what we were grepping for, if not we didn't...

if [ code to see if mmc card plugged in ]; then...
