This script provides a compact and easy-to-read display of the information provided by ip address, ip route and ip link commands from the iproute2 package.
I created it because, while the ifconfig and route commands are now deprecated on Linux, their outputs were really better than the outputs of their successors listed above.
This script uses the new commands but displays a much cleaner output (more compact and structured, adding colored titles, sorting interfaces, keeping only the most useful information, ...).
You can see examples lower.

From the folder of your choice, download and extract the ZIP archive from GitHub :
wget "https://github.com/falzonv/ipshow/archive/main.zip"
unzip main.zip
Note : if you are familiar with Git, you may prefer to use git clone "https://github.com/falzonv/ipshow" ipshow-main so you can easily get updates with git pull
Copy the script in the bin folder of your home directory :
cp ipshow-main/ipshow.sh /home/${USER}/bin/ipshow.sh
Note : using the git clone alternative, you may prefer to create a symbolic link from your bin folder using ln -s /path/to/folder/ipshow-main/ipshow.sh ipshow.sh
If the bin folder doesn't exist in your home directory, create it using the mkdir /home/${USER}/bin command.
On many systems, creating the home's bin will automatically add it to the PATH when you open a new terminal or a new session.
If this is not the case for you, you can add it manually by inserting the line export PATH="/home/${USER}/bin:$PATH" in the /home/${USER}/.bashrc file (you will need to open a new terminal or a new session to see the change applied).
Once the installation is completed, you should be able to run the script from anywhere in the system using :
ipshow.sh
You can use ipshow.sh -h or ipshow.sh --help to see the options.
By default, only IPv4 information are displayed in the script's outputs for ip address and ìp route.
If you want to display IPv6 information instead, simply use ipshow.sh -6 or ipshow.sh --ipv6.
- If you don't want or cannot copy/link the script in the home's
binfolder (or add the home'sbinfolder to the PATH), you will need to go in theipshow-mainfolder to execute the script with./ipshow.sh - If you run into permissions issues, make sure the script is executable for the current user by going in the folder where the script is located (either
/home/${USER}/binoripshow-main) and runningchmod u+x ipshow.sh
When launched in a terminal, sections and columns titles are also colorized for easier reading.

Usage: ipshow.sh [OPTION]
This script makes the outputs of "ip address", "ip route" and "ip link"
more compact and easy to read.
OPTIONS
-6, --ipv6 By default, only IPv4 information is displayed in the
script's "ip address" and "ip route" outputs. With this
option, IPv6 information is displayed instead.
-h, --help To display this message again.
