What is the equivalent terminal command to ipconfig /all?

The only thing missing from ifconfig are the gateway and DNS servers.

15.04 and newer

To get the DNS and Gateway info just type:

nmcli dev show eth0

The output lists some device parameters including some IP4.DNS[x] entries, which show the DNS servers and a IP4.ADDRESS[1] line which lists the IP and Gateway used (look for the gw = ???.???.???.??? part at the end of the line up to 15.10). On 16.04 and newer versions there is a IP4.GATEWAY line which is pretty self explanatory.

Replace eth0 with the actual device name you're using, which may not be the same. To get a list of devices and their status type:

nmcli dev status

Up to and including 14.10

You can get these with nm-tool (in Ubuntu versions prior to 15.04) which BTW is the command line version of network manager.

To run it just type in a terminal:

nm-tool

If you're using Ubuntu 15.04 or newer the nm-tool has been replaced by the nmcli command which is different. Check the section called "15.04 and newer" above this one in this case.

ipconfig shows things like hostname, DNS servers, those are in a different place than just IP addresses in linux, so you will need a couple of commands.

hostname
ifconfig -a
cat /etc/resolv.conf

That shows what I want to see 99% of the time, but ipconfig /all also shows things like DHCP lease times and servers.

cat /var/lib/dhcp/dhclient.leases

Was looking at few links and finally found the below working:

nmcli dev list | grep IP4

The output is:

IP4.ADDRESS[1]:                         ip = 195.168.0.107/24, gw = 192.168.0.1
IP4.DNS[1]:                             192.168.0.1
IP4.DOMAIN[1]:                          local

Also all the network related details can be found using putting simply:

nmcli dev list eth0
