Any way around grep and awk or Raku?
$ nmcli device status | grep eno2 | awk '{print $3}'
connected
nmcli device status | grep eno2 | grep connected
This will either return connected, or a blank line, without using
awk or any other string manipulation.
Or even easier, you can send the output to null and check the exit
code.
if nmcli device status | grep eno2 | grep connected > /dev/null; then
# connected
else
# not connected
fi
Actually, doesn't one have to be a bit more careful with the pattern?
Notice what the status is for wlp4s0.
[egreshko@meimei ~]$ 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`
Make sure you add that before the last grep. It would be simpler to
grep for " connected" instead.
