status

Synopsis

pibootctl status [-h] [-a] [--json | --yaml | --shell] [pattern]

Description

Output the current value of modified boot time settings that match the specified pattern (or all if no pattern is provided). The --all option may be specified to output all boot settings regardless of modification state.

Options

pattern

If specified, only displays settings with names that match the specified pattern which may include shell globbing characters (e.g. *, ?, and simple [classes]).

-h, --help

Show a brief help page for the command.

-a, --all

Include all settings, regardless of modification, in the output. By default, only settings which have been modified are included.

--json

Use JSON as the output format.

--yaml

Use YAML as the output format.

--shell

Use a var=value format suitable for the shell.

Usage

By default, the status command only outputs boot time settings which have been modified:

$ pibootctl status
+-------------+-------+
| Name        | Value |
|-------------+-------|
| i2c.enabled | on    |
| spi.enabled | on    |
+-------------+-------+

The full set of settings (which is usually several pages long, and thus will implicitly invoke the system’s pager) can be displayed with the --all option:

$ pibootctl status --all
+------------------------------+----------+--------------------------+
| Name                         | Modified | Value                    |
|------------------------------+----------+--------------------------|
...
| i2c.baud                     |          | 100000                   |
| i2c.enabled                  | x        | on                       |
| i2s.enabled                  |          | off                      |
| serial.baud                  |          | 115200                   |
| serial.clock                 |          | 48000000                 |
| serial.enabled               |          | on                       |
| serial.uart                  |          | 0 (/dev/ttyAMA0; PL011)  |
| spi.enabled                  | x        | on                       |
| video.cec.enabled            |          | on                       |
...

Note that when --all is specified, a “Modified” column is included in the output to indicate which settings are no longer default.

The list of settings can be further filtered by specified a pattern with the command. The pattern can include any of the common shell wildcard characters:

• * for any number of any character
• ? for any single character
• [seq] for any character in seq
• [!seq] for any character not in seq

For example:

$ pibootctl status --all i2c.*
+-------------+----------+--------+
| Name        | Modified | Value  |
|-------------+----------+--------|
| i2c.baud    |          | 100000 |
| i2c.enabled | x        | on     |
+-------------+----------+--------+

For developers wishing to build on top of pibootctl, options are provided to produce the output in JSON (--json), YAML (--yaml), and shell-friendly (--shell). These combine with all aforementioned options as expected:

$ pibootctl status --json --all i2c.*
{"i2c.baud": 100000, "i2c.enabled": true}
