# There are a number of modifiers that are allowed to be used in some |
5 |
|
# of the different fields. They provide the following subsitutions: |
6 |
|
# %n - the "kernel number" of the device. |
7 |
|
# For example, 'sda3' has a "kernel number" of '3' |
8 |
|
# %k - the kernel name for the device. |
9 |
|
# %M - the kernel major number for the device |
10 |
|
# %m - the kernel minor number for the device |
11 |
|
# %b - the bus id for the device |
12 |
|
# %c - the string returned by the PROGRAM. (Note, this doesn't work within |
13 |
|
# the PROGRAM field for the obvious reason.) |
14 |
|
# %s{filename} - the content of a sysfs attribute. |
15 |
|
# %% - the '%' char itself. |
