Hi Michael,
Hi all
Trying to understand how to get the last result. For example: sspi 1:0.3 24 700002; sspi 1:1.3 24 730000
The $? shall do the job.
=> true => echo $? 0 => false => echo $? 1

Michael
Or have I misunderstood something?
Now I need to have the last output of the last command to compare in one script. Any idea?
