Legacy

This document describes some legacy features.

Note: please do not do this, this is only kept to assist debugging.

Legacy mode is activated when no option starting with "--" is given. In this case hwinfo works as follows:

hwinfo [debug=deb_flag] [log=log_file] [list[+]=hw_item] [[+|-]probe_option1] [[+|-]probe_option2] ...

Examples:

  • hwinfo - probes for nearly everything
  • hwinfo +all - probes for everything
  • hwinfo log=hw_log - default probing, output is written to hw_log. Please don't use hwinfo >some_log 2>&1 to store the output into a log file!
  • hwinfo -all +pci +int - probe for pci devices

Note that int should almost always be active.

Some probing flags do not stand for complete modules but enable additional features; e.g. bios.vesa or block.cdrom.

Example:

hwinfo -all +block +int

gives a list of all block devs

hwinfo -all +block.cdrom +int

additionally reads the iso9660 info.

The list of supported flags varies from version to version. To get a list of the actual set of probing flags, call hwinfo -all and look at the top of the log.
