Any way around grep and awk or Raku?

       $ nmcli device status | grep eno2 | awk '{print $3}'

nmcli device status | grep eno2 | grep connected

This will either return connected, or a blank line, without using awk or any other string manipulation.
Or even easier, you can send the output to null and check the exit code.
if nmcli device status | grep eno2 | grep connected > /dev/null; then
   # connected
else
   # not connected
fi

Actually, doesn't one have to be a bit more careful with the pattern?

Notice what the status is for wlp4s0.

[egreshko@meimei ~]$ if nmcli device status | grep wlp4s0 | grep connected > /dev/null; then echo connected; else echo not connected; fi
connected

oops...


Forgot to include...

[egreshko@meimei ~]$ nmcli device status
DEVICE             TYPE      STATE         CONNECTION
enp2s0             ethernet  connected     enp2s0
virbr0             bridge    connected     virbr0
vnet0              tun       connected     vnet0
78:00:9E:27:6B:3D  bt        disconnected  --
wlp4s0             wifi      disconnected  --
lo                 loopback  unmanaged     --
virbr0-nic         tun       unmanaged     --


Ah poop!  "disconnected" contains "connected"!

I added a `grep -v dis`

Silly me, just add a space in front of the fragment
to drop the "dis"

     grep " connected"

:-)
