Checking Linux IP address bash: ifconfig: command not found
In Linux ifconfig is a basic command used to check the IP address. Recently, I did a fresh install of Redhat Linux on a virtual machine. Logged in as local user, I checked the IP address using of ifconfig command. I got a command not found error.
Linux IP address bash: ifconfig: command not found
I tried to verify if ifconfig is really missing. Ifconfig as I know is a built-in Linux system command. I check under the /sbin/ folder and it’s present. Thus, the command could not be found, might be caused by the lack of privilege to run the command.
Linux IP address checking with ifconfig command
I login as root user and try to run ifconfig to check the IP address surely everything went okay.

I think if this is a permission issue, it will tells you permission denied.
Most probably this is a $PATH issue. Your user $PATH is not set to include /sbin, hence when you execute
$ ifconfig
You get command not found. To verify if this is indeed a $PATH issue, execute with a full path
$ /sbin/ifconfig
If returned success, consider adding /sbin to your user $PATH. (root already has /sbin included in $PATH)
