Centos cannot find the ifconfig command

Source: Internet
Author: User

# Ifconfig

The system prompts that the command does not exist.

Use #/sbin/ifconfig

Cause: the default environment variable is incorrect.

Echo $ path is executed for common users and root users respectively. Four addresses are missing in path:/sbin:/usr/local/sbin: /usr/Kerberos/sbin

Ifconfig is exactly in/sbin.

Or

CAT/etc/profile. No environment variables about/sbin can be found.

Su enters root and runs gedit/etc/profile (recently used to use gedit in Linux)

Add the following statement at the end of the file:

Path = $ path:/sbin # append the/sbin directory after the PATH variable

Export Path = $ path:/sbin # Set the variable to global

Save and exit.

Modify/home/user/. bash_profile and add/sbin:/usr/local/sbin:/usr/Kerberos/sbin to the path.

After the modification, run the command: .. bash_profile. You can also log off or restart it to make the modified content take effect.

Then sudo ifconfig, and then OK.
