[GRASS-dev] set null compression permanently

GRASS GRASS developer

Hi,

I just tried to enable compression of null files, using within a session:

export GRASS_COMPRESS_NULLS=1

r.null -z map=mymap

This works fine, but how can I set this permanently. Can I for example use g.gisenv for that? Or do I need to set this every time when starting a new session?

Regards,

Paulo

it's not GRASS variable. Environmental variables can be defined in
$HOME/.grass7/bashrc (or env.bat on Windows). In your case

export GRASS_COMPRESS_NULLS=1

put to bashrc/env.bat file. Ma
