Resolve commnd not find

Cause: the command fdisk is not in your command search path.

Solution 1: Add fdisk to your command search path

The method is as follows:

First, check your current command search path:

[Root @ localhost sbin] # echo $ PATH
/Usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/bin:/usr/X11R6/bin: /home/vincent/bin
Check the path of the fdisk command.

[Root @ localhost home] # whereis fdisk
Fdisk:/sbin/fdisk/usr/share/man/man8/fdisk.8.gz

We can see that the fdisk command is no longer in the current command search path

Then, add fdisk to the search path of the current command.

Ln-s/sbin/fdisk/usr/kerberos/bin

Now you have added fdisk to the search directory of the current command. Let's take a look.

[Root @ localhost home] # cd/usr/kerberos/bin
[Root @ localhost bin] # ls
Fdisk gss-client kinit kpasswd krlogin ksu rcp rsh telnet v4rcp
FTP kdestroy klist krb524init krsh kvno rlogin sim_client uuuclient
[Root @ localhost bin] # cd/usr/Kerberos/bin
[Root @ localhost bin] # ll

Run fdisk now.

[Root @ localhost ~] # Fdisk-l

Disk/dev/sda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065*512 = 8225280 bytes

Device boot start end blocks ID system
/Dev/sda1*1 6 48163 + 83 Linux
/Dev/sda2 7 515 4088542 + 83 Linux

Succeeded. Because the virtual machine is used, other disks are not visible.

Method 2:

Super simple, use $ su-

Command.

[Vincent @ localhost grub] $ su-
