The iio_attr utility has a few main options, which control what the main utility of the application is.
-d, --device-attr

-C --context-attr
Read and Write IIO Context attributes
-D --debug-attr

local:
with no address part
-i, --input-channel
Filters channels by input channels only
-o, --output-channel
Filters channels by output channels only
-s, --scan-channel
Filters channels by scan channels only
-I, --ignore-case
When pattern matching devices, channels or attributes, ignore case
-g, --generate-code <arg>
