Ram's questions

我在 FreeBSD 机器 (xxx.yyy.zzz.net) 上运行命令并获取输出

命令

sudo camcontrol devlist | grep -o 'ada[0-9]' | while read -r a ; do sudo camcontrol identify $a | grep rotating ; done

输出

media RPM             non-rotating
media RPM             non-rotating
media RPM             non-rotating

我正在尝试使用另一台机器上的 ssh 运行相同的命令

命令

ssh xxx.yyy.zzz.net sudo camcontrol devlist | grep -o 'ada[0-9]' | while read -r a ; do sudo camcontrol identify $a | grep rotating ; done

错误

sudo: camcontrol: command not found
