... echo $STRING
exit <---- ( or return )

i find rescue the value return of the script B ( the last echo )
in a variable in the shellA
es:

Code:

vareturn=$( remsh hostB shellb | read var ; echo $var )

but varreturn is empty .....

i try this :

Code:

vareturn=$(remsh hostb shellb ;read var ; echo $var )
