# update-sysfs(8)

Linux sysfs attributes update tool

## NAME

update-sysfs - Linux sysfs attributes update tool

## DESCRIPTION

This tool update the Linux **sysfs** attribute values and modify their file mode or owner, usually during the system boot.

Note that this tool and its configuration files are concerned with the */sys* filesystem and should not be confused with the */etc/sysctl.conf* configuration which is concerned with the */proc/sys* filesystem instead.

## FILES

- */etc/sysfs.conf*

  The main configuration file. It gets loaded first if readable.

- */etc/sysfs.d/\*.conf*

  The optional configuration fragment files. These get loaded after the main configuration file, if readable, in glob order.

## SEE ALSO

[**sysfs.conf**(5)](/sysfs.conf/5.md).
