LsSysFirmware - command ls /sys/firmware

The ls -lanR /sys/firmware command provides information for the listing of the /sys/firmware directory. The parser class can also process ls -alZR /sys/firmware command output.

See insights.parsers.ls.FileListing for more information.

class insights.parsers.ls_sys_firmware.LsSysFirmware(context, extra_bad_lines=None)

Bases: FileListing

Parses output of ls -lanR /sys/firmware or ls -alZR command.

Warning

For Insights Advisor Rules, it’s recommended to use the insights.parsers.ls.LSlanFiltered and add the "/sys/firmware" to the filter list of Specs.ls_lan_filtered_dirs instead.
