how to set a var that is what was last written in the shell

Hello there !

Ok, so here's the thing. I've wrote a script to send sms using gammu. The problem is that sometimes if my cell has no network, it will give me an error. In that case I would like my script to try and send the message again.

Here is the last thing my script does :

echo "$message" | gammu --sendsms TEXT $number

after what, two possibilities :
->gammu says "waiting for network answer..OK, message reference=237"
->gammu says something like "waiting for network answer... error, message reference=-1"

An easy way for me to test if the sms was sent would be to be able to assign to a var this sentence and then for example test its length or the last two characters.
So, does anyone know how to do that ?

Thanks and please be specific as it's my first script

.

Code:

message=`echo "$message" | gammu --sendsms TEXT $number`

Those are accent marks, not single quotes around the string. However, an easier way is probably to check the return code:

Code:

echo "$message" | gammu --sendsms TEXT $number
RC=$?
if [ "$RC" != "0" ]
then
   echo "Error: $RC from gammu"
fi
