作为 root 用户：

命令 1：

which fio

输出 1：

no fio in ($path)

命令2：

fio

输出 2：

bash: fio: command not found

我找到了一些与此相关的帖子。我还尝试将 fio 的路径（which fio非 root 用户给出的路径）添加到 ~/.bashrc 并尝试获取文件，但没有成功。我还应该做哪些更改才能使其正常工作。请有人帮助我。提前致谢。

答案1

您的 PATH 变量的内容是什么？（请参阅 的输出export | grep PATH。我猜想它/usr/local/bin/不在 root 的 PATH 中。您可以将其添加到 root 的路径中。从其中一个系统文件夹创建符号链接，或者只需使用完全限定路径运行该命令。
