bad exit value for "rcctl ls failed"

This looks weird: gate5b# rcctl ls failed smtpd gate5b# x=$(rcctl ls failed) && rcctl restart $x gate5b# rcctl ls failed smtpd gate5b# echo $? 1 WTH? gate5b# x=$(rcctl ls failed) || rcctl restart $x smtpd(ok) gate5b# rcctl ls failed gate5b# echo $? 0 This is confusing. Imagine grep would exit 1 if it has found something. Regards Harri
