I've not used nmcli in any of its more intricate ways, but are there

('link/carrier state')?
I can grab some hints of the latter with /sys/class/net/eth0/carrier,
but
would prefer an approach that is harmonised through nmcli. Are there
a
couple of sub-commands that can be used rather than parsing the full
'nmcli
dev show' output? e.g. to output a couple of specific fields.
Hi, how about: LANG=C nmcli -t -m tabular -f WIRED-PROPERTIES.CARRIER device show "$DEV" Thomas
