Aw: [GRASS-user] grass in the terminal...

Hi, you have to call grass by typing in grass[+ version number without decimal delimiter], that means grass63 for grass 6.3 . Hope it will help. Tim - Original Nachricht Von: Alfredo Alessandrini [EMAIL PROTECTED] An: grass-user@lists.osgeo.org Datum: 29.05.2008 12:38

[GRASS-user] Just a comment about the GRASS-book

I am using the GRASS book since the beginning of the year. I just wanted to say that the book is simply The tutorial. I was wondering if the 1st GRASS-book is worthy to obtain (any information that is not in the 2nd and 3rd edition?). Thanks to Markus and Helena. Nikos

Re: [GRASS-user] How many modules has GRASS?
