# mbr

我不明白。我安装了软件包mbr(也是的软件包mbr-install),但是当我尝试执行它时。然后 bash 找不到它。

# echo $PATH

/home/user123/perl5/bin:/sbin:/home/user123/Desktop/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

应该/sbin在哪里安装它。有人知道为什么即使安装了包也找不到命令吗?

答案1

我推荐这个过程(我猜你是用 root 来做的,对吧?):步骤 1:检查文件系统上是否存在可执行文件。使用updatedb更新位置数据库,然后执行locate mbr 步骤 2:找到后,尝试使用其完整路径启动它。如果被拒绝,错误会显示错误所在。
