rules.
.SH "OPTIONS"
.TP
.B \-V
Print the version information.
.TP
.B \-r
Print the
.B udev_root
directory. When used in conjunction with a query for the node name, the

will be prepended.
.TP
.BI \-q " query_type"
Query the database for specified value of a created device node.
.RB Needs " \-p " or " \-n " specified.
.br
Valid types are:
.BR name ", " symlink ", " mode " ," owner " , " group " , " path " or " all.
.TP
.BI \-p " sysfs_path"
Specify the sysfs path of the device to query.
.TP
.BI \-n " name"
Specify the name of the node or the symlink for the device to query.
Partition names generated with the NAME{all_partitons} option can not be
queried, the main device must be used instead.
.TP
.B \-a
Print all
.BI SYSFS{ filename }
attributes along the device chain. Useful for finding
unique attributes to compose a rule.
.RB Needs " \-p " specified.

[PATCH] udevinfo symlink reverse query Thanks to Olaf Hering <olh@suse.de> for this patch. It's possible now to feed the -n option of udevinfo with a symlink. I've also added a 'all' attribute, but no more text, it's all in the included man page :) 2004-03-02 10:47:59 +03:00			`.BR name ", " symlink ", " mode " ," owner " , " group " , " path " or " all.`

[PATCH] cleanup mult field string handling Here I try to cleanup our various multifield iteration over the strings. Inspired by our nice list.h we now have a macro to iterate over the string and process the parts of it: It makes the code more readable and we don't change the string while we process it like the former strsep() does. Example: foreach_strpart(dev->symlink, " ", pos, len) { if (strncmp(&dev->symlink[pos], find_name, len) != 0) continue; ... } For the callout part selector %c{2} we separate now not only by space but also newline and return characters, cause some programs may give multiline values back. A possible RESULT match must contain wildcards for these characters. Also a bug in the recent udevinfo symlink query feature is fixed. 2004-03-04 05:16:35 +03:00			`Partition names generated with the NAME{all_partitons} option can not be`
			`queried, the main device must be used instead.`

[PATCH] udev - switch SYSFS_file to SYSFS{file} Here we switch the configs and man pages to the new attribute syntax. Also the 'partition trick' is mentioned in udev.8 I think it's more clear visible now, that inside the brackets are user supplied values used and not some magic keys handled: 'SYSFS_dev' is now 'SYSFS{dev}' The old syntax is still supported. 2004-02-17 12:27:01 +03:00			`.BI SYSFS{ filename }`
