ubuntu ip: command not found

The error message "ubuntu ip: command not found" indicates that the "ip" command is not found on your Ubuntu system.

The "ip" command is used to manage network interfaces and routing tables on Linux systems. It is included in the "iproute2" package, which should be installed by default on most Ubuntu systems.

To resolve this issue, you can try installing the "iproute2" package using the following command:

sudo apt-get install iproute2

If the package is already installed, you may need to check your system's PATH environment variable to ensure that the directory containing the "ip" command is included. You can do this by running the following command:

echo $PATH

This will display a colon-separated list of directories where your system looks for executable files. Make sure that the directory containing the "ip" command (usually "/sbin" or "/usr/sbin") is included in the PATH variable. If it is not, you can add it using the following command:

export PATH=$PATH:/sbin:/usr/sbin

This will add "/sbin" and "/usr/sbin" to the end of the PATH variable. Note that this will only modify the PATH variable for the current shell session. To make the change permanent, you will need to add the export command to your shell's startup files (such as "~/.bashrc" or "~/.bash_profile").
