In windows I can use ipconfig /all and this displays all the info about my connection.
In terminal using ifconfig does not and only supplies limited info. I can use network manager, but it would be useful to know the command line alternative.
So my question is: what is the command line to supply ip address, gateway, subnet mask, DNS the same way ipconfig /all supplies in Windows.
Thanks all
The only thing missing from ifconfig are the gateway and DNS servers.
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
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If you're using Ubuntu 15.04 or newer the nm-tool has been replaced by the nmcli command which is different.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.
nmcli dev show eth0 results in this: Error: 'dev' command 'show' is not valid.

nmcli dev help to see which commands are available.
nmcli d list which shows info for all connections, connected or not.

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
nmcli dev list | grep IP4 means take the output of nmcli dev list and then feed it (using the pipe |) into grep and keep lines that contain regex pattern IP4.

Here's the simplest equivalent i could find for ubuntu 17.04
nmcli device show
Sample output (ip4 stuff only):
nmcli device show | grep IP4
IP4.ADDRESS[1]: 172.27.35.55/24
IP4.GATEWAY: 172.27.35.1
IP4.ROUTE[1]: dst = 169.254.0.0/16, nh = 0.0.0.0, mt = 1000
IP4.DNS[1]: 172.27.35.1
IP4.ADDRESS[1]: 127.0.0.1/8
IP4.GATEWAY:
I needed to work out what DHCP server I was connected to via Ubuntu 14.04 so I used this command:
nmcli dev list|grep DHCP4
as this is what I wanted only from the original command "nmcli dev list"
DHCP4.OPTION[1]: expiry = 1464073312
DHCP4.OPTION[2]: domain_name = [omitted_proper_details]
DHCP4.OPTION[3]: broadcast_address = 10.1.45.255
DHCP4.OPTION[4]: dhcp_message_type = 5
DHCP4.OPTION[5]: dhcp_lease_time = 432000
DHCP4.OPTION[6]: ip_address = 10.1.45.132
DHCP4.OPTION[7]: subnet_mask = 255.255.255.0
DHCP4.OPTION[8]: dhcp_renewal_time = 216000
DHCP4.OPTION[9]: routers = 10.1.45.1
DHCP4.OPTION[10]: domain_name_servers = 10.1.26.10 10.1.20.10
DHCP4.OPTION[11]: dhcp_rebinding_time = 378000
DHCP4.OPTION[12]: network_number = 10.1.45.0
DHCP4.OPTION[13]: dhcp_server_identifier = 10.1.20.10
Gives me all the DCHP/DNS details I need, just like ipconfig /all
