Can't you achieve the desired effect portably without requiring any
xargs special casing with e.g.
(stuff) | xargs -t -i sh -c 'ssh -q [EMAIL PROTECTED] "uname -a"; ret=$?; test
$ret == 255 && exit 0; exit $ret'
Or if you don't care what the exit value is,
(stuff) | xargs -t -i sh -c 'ssh -q [EMAIL PROTECTED] "uname -a" || :'
Although I think I would argue xargs is really not the right tool for
the job here at all -- you're only using it to substitute {} for a
variable, and the shell is more than capable of doing that on its own
(not to mention the needless use of awk):
$ for H in `seq 5004 5006`; do ssh -q [EMAIL PROTECTED] "uname -a"; done
Also, it sounds like you might want to check out 'dsh'.
