The data are added to output_data at first, and then they are printed all at
once using print_data(), that takes care of proper alignment and display.
The static 'width' values defined in NmcOutputField columns are not used now,
but dynamically computed maximal widths override them.
That way it is not displayed by default:
$ nmcli general status
But can be explicitly requested:
$ nmcli -t -f running,version general status
$ nmcli -f all general status
E.g. Fedora initscripts do this in
/etc/sysconfig/network-scripts/network-functions
is_nm_running ()
{
[ "$(LANG=C nmcli -t --fields running nm status 2>/dev/null)" = "running" ]
}
nmcli general logging [level <log level>] [domains <log domains>]
Examples:
nmcli general logging - print current level and domains values
nmcli general logging level ERR - change logging level to ERR
nmcli general logging level DEBUG domains DNS - change logging level to DEBUG and domains to DNS
nmcli g l domains DEFAULT - set default log domains (the ones active when NM)
They basically contain operations previously available via 'nmcli nm'.
'nmcli nm' is still kept for backward compatibility.
Usage:
nmcli switch [all|networking|wifi|wwan|wimax [on/off]]
nmcli general [status|permissions]
Examples:
nmcli switch all - show all switches
nmcli switch wifi off - switch Wi-Fi off
nmcli g s - show NM status
nmcli g p - show NM permissions
nmcli gets NM version and compares it with its own and complains
when they differ. This is to indicate that the results are not reliable,
because the API could differ. '--nocheck' switches the checks off.
DISCONNECTING: the only active network connection is now being disconnected
LOCAL, SITE, GLOBAL: one-stop items for level of connectivity, which
we'll use to show when we think we're actually connected to the internet
or behind a captive portal or something
When getting status of NetworkManager via 'nmcli nm ...' and NetworkManager
is not running, do not call its D-Bus methods. It prevents NM to be implicitly
executed when configured as D-Bus activated service.
'enable' command queries and sets NetworkingEnabled property. It should be used
by users. Previous 'sleep' command that actually did enable/disable,
really calls Sleep() now and is not meant for common usage.
Modifications are mainly for multiline mode to ease parsing - each
field name is prefixed with a section name.
'dev list' now also supports printing particular sections specifed via
'--fields' option.
