Top Forums Shell Programming and Scripting How to input the return value (1 or 0) ping cmd to a variable Post 302479704 by jao_madn on Sunday 12th of December 2010 03:41:55 PM

By the way thanks for the reply i solve my problem by just not using a variable i guess csh automatically declare the return values of the previous command as status variable
Code:
#!/usr/bin/csh -f
foreach host(host1 host2 host.....)
ping -t 30 $host 5 >& /dev/null
    if( status == 0 ) then
        rsh $host " uname -a"
    else
        echo " ---$host unavailable---"
    endif

echo " ----- END -----"
sleep 1

end

I used redirection for the stdout and stderr so that no ping result command appears in my script
