问题

fdisk -l 查看硬盘及分区信息

[root@CentOS-85-64-minimal ~]# dfisk -l
-bash: dfisk: command not found

原因:命令fdisk 不在你的命令搜索路径中

解决

方法一

先进入root用户,再查看你当前的命令搜索路径:

[root@CentOS-85-64-minimal ~]#  echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin

再查一下fdisk命令在哪个路径下:

[root@CentOS-85-64-minimal ~]# whereis fdisk
fdisk: /usr/sbin/fdisk /usr/share/man/man8/fdisk.8.gz

我们可看到fdisk 命令不再当前命令搜索路径里,那么我们将fdisk添加到当前命令搜索路径中即可:

ln -s /usr/sbin/fdisk /usr/local/bin

好现在已经将fdisk 添加到当前命令搜索目录中去,我们可以去看一下:


dfisk -l

方法二

不需要添加到环境变量中,直接在sbin目录下运行命令fdisk -l

[root@CentOS-85-64-minimal sbin]# whereis fdisk
fdisk: /usr/sbin/fdisk /usr/share/man/man8/fdisk.8.gz

然后进去目录:

cd /usr/sbin
./fdisk -l 或者 ./fdisk

如:

[root@CentOS-85-64-minimal ~]# cd /usr/sbin
[root@CentOS-85-64-minimal sbin]# ./fdisk -l
