In Linux, the "bash ifconfig command not found" command appears in ifconfig.

It seems strange to use centos for the first time. It is not as good as the windows operating interface. I cannot find many things and I don't know how to find them. My computer is in the English version of centos 5.4:
During user use, I want to check my network configuration and find that I cannot enter the "ifconfig" command. If an error occurs, I will start to look for relevant information, an error occurred in my network configuration, as shown below:

[Wang @ protronic ~] $ Ifconfig

Base: ifconfig: Command not found

My modifications are as follows:

[Wang @ protronic ~ ] $ Su

Passwod:

[Root @ protronic Wang] #/etc/profile

Comment out the following if statement:

# Path manipulation

If ["EUID" = "0"]; then

Pathmunge/sbin

Pathmunge/usr/sbin

Pathmunge/usr/local/sbin

Fi

To:

# Path manipulation

# If ["EUID" = "0"]; then

Pathmunge/sbin

Pathmunge/usr/sbin

Pathmunge/usr/local/sbin

# Fi

Save.

Now I understand that under/etc/profile, all the system configuration files are saved in/etc.

Of course, you can also directly use/sbin/ifconfig.
