I believe this may have been written with the intention of "if the variable x contains any value, then there must be something failed", but then it uses regular shell job control with && , which relies on exit values returned from the task, in this case rcctl and its parameters (ls failed) because "rcctl ls failed" returns a 1 if something has failed, "&& rcctl restart ..." is never executed. I believe this may have been what was intended: x=$( rcctl ls failed ); [ -n "$x" ] && rcctl restart $x
