To get interactive help

As seen before, for basic help type help. Or for help on a set of sub commands type the command followed by help. For example hf mf help. Many commands uses the -h / --help parameter to show a help text.
The Proxmark3 client now also supports tab-autocomplete in both commands and filenames. Like for instance hf mf a<tab> will give you a list of three availble commands.
This feature is quite powerful and similar to your normal shell experiences.

Hardnested tables
^Top
Hardnested tables are compressed with LZ4 for a good compromise between space and decompression speed.
If you are under very space constrained environment, you can recompress the tables with BZip2 and delete the LZ4. It will break the git workdir but if space is a concern, you're not deploying the source and .git of > 80Mb anyway, do you?
cd client/resources/hardnested_tables
lz4 -dm --rm *lz4
bzip2 *.bin
If you want top speed, you can decompress the tables in advance. Keep the .lz4 files, so you can always just rm *.bin to save space again.
cd client/resources/hardnested_tables
lz4 -dkm *lz4
| Compression | Size in Mb | Speed(*) |
|---|---|---|
| LZ4 | 9 | 1 |
| BZip2 | 2 | 6.5x slower |
| None | 704 | 2.5x faster |
(*) rough idea of relative speeds, real numbers depend on your actual system
