I already figured out that on Linux I can list network devices

(cd /proc/net/dev_snmp6/ && for device in *; do echo $device; done|sort)

but how can I get the ipv4 address of the device?

I do not have ifconfig/ip installed - and I'd like to keep it this way.

  • basically net-tools are not installed and i want to just "standard" unix tools, like cat / sed/ awk /bash – Mandragor Feb 16 '17 at 19:12

    @GAD3R, Thomas, Rui F Riberio: I think you all misread the question. You've linked a completely unrelated question while marking dup.

    hostname -I does the work. – Rahmani Aug 19 '21 at 07:19

Using netstat -ie you should be able to see all interfaces and any information associated with them.

Example:

user@host:~$ netstat -ie
Kernel Interface table

          inet addr:43.96.21.119  Bcast:43.96.21.255  Mask:255.255.255.0

    thanks for pointing out netstat, but this is also part of the net-tools which are not installed (ifconfig etc.) – Mandragor Feb 16 '17 at 19:12
