examples/mdev_fat.conf

#
# This is a sample mdev.conf
#

# Provide user, group, and mode information for devices.  If a regex matches
# the device name provided by sysfs, use the appropriate user:group and mode
# instead of the default 0:0 660.
#
# Syntax:
# [-][ENVVAR=regex;]...devicename_regex user:group mode [=path]|[>path]|[!] [@|$|*cmd args...]
# [-][ENVVAR=regex;]...@maj,min[-min2]  user:group mode [=path]|[>path]|[!] [@|$|*cmd args...]
# [-]$ENVVAR=regex                      user:group mode [=path]|[>path]|[!] [@|$|*cmd args...]
#
# [-]: do not stop on this match, continue reading mdev.conf
# =: move, >: move and create a symlink
# !: do not create device node
# @|$|*: run cmd if $ACTION=remove, @cmd if $ACTION=add, *cmd in all cases
