# ifconfig

Prompt command does not exist

Use #/sbin/ifconfig to

Cause: The system default environment variable is not set

The Echo $PATH is executed separately under the normal user and root user, and the PATH has four missing addresses:/sbin:/usr/sbin:/usr/local/sbin:/usr/kerberos/sbin

And, Ifconfig is exactly in the/sbin inside.

Or

Under Cat/etc/profile, you can find no environment variables about/sbin.

Su goes to root, runs Gedit/etc/profile (just playing Linux, used gedit)

Add the following statement at the end of the file:

Path= $PATH:/sbin # Append/sbin directory after PATH variable

Export path= $PATH:/sbin# Set Variable to global

Save and exit.

Modify the/home/user/.bash_profile, adding/sbin:/usr/sbin:/usr/local/sbin:/usr/kerberos/sbin to the path after path.

After the change is complete, execute the command:. . Bash_profile, you can also log off or restart to make the content you just modified take effect.

Again, Sudo ifconfig, it's OK.
