Add/sbin to the path

The command fdisk-l failed to be executed, but the command/sbin/fdisk-l succeeded.

<1> Use whereis to view the directory where the command is located
For example, whereis fdisk
Fdisk:/sbin/fdisk/usr/share/man/man8/fdisk.8.gz

The fdisk directory is/sbin/fdisk.

<2> use! Echo: view the path of the current environment
Example :! Echo
Echo $ path
/Usr/Kerberos/bin:/usr/local/bin:/usr/x11r6/bin:/home/unimon/bin

Check that the/sbin directory does not exist. Therefore, add/sbin to the path.

<3> Use VI to open the. bashrc file,
VI ~ /. Bashrc

<4> Add the following line to the. bashrc file (reset the path of path)
Path = "$ path:/sbin"

<5> execute the command source ~ /. Bash

Finally, the execution of fdisk-L is successful!
