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

Or have I misunderstood something?

...

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

Now I do see about what you were asking for. I've misunderstood you.

My general idea is to provide an our variable to stdout to all the command that give some result or exptend command interface to something like

do_xxxx() {

redirect-stdout -> enviroment

do somenthing

return

}
