Readme for kparams-0.1.0.0

[back to package description]

kparams (in Haskell)

Extracts kernel parameter values from /proc/cmdline. Handles bare and quoted parameters. This is a rewrite of the original kparams in Haskell.

See kernel.org's docs on kernel parameters for more information. While the docs mention using double-quotes to protect values with spaces, we also recognize single-quotes and certain escape sequences to support things like quoted="\"value\"".

Check out test/ to see examples of what we can extract.

Usage

$ kparams PARAM_NAME [DEFAULT_VALUE]

What's the difference between the shell implementation of kparams and this?

They should be functionally similar. Error messages will differ, although they should error under the same conditions. Most significantly, this version is hundreds of times faster.
