GRASS lock problem

Several of us are getting that exact error message ( with our own machine n=
ame,
of course). I don't know what to try next, but I believe Markus is
looking into it (see quote below).

Hi friends,

just now I have installed GRASS 4.2.1 (V.21) on a "fresh" Linux System
running SuSe6.0-Linux.
But I could not reproduce your error message. I downloaded the current
Linux binaries and strickly followed my instructions (without extra
knowledge!).
So we have to proceed stepwise to locate the problem. You may post
personally to me, I will send the solution to the list then, when
(not if) we find it:

1. Are you all running *Redhat* Linux? Which version?

2. Is there existing the file
/usr/local/grass42/etc/lock

   Execute it, it should say

      /usr/local/grass42/etc > lock
      usage: lock file pid

3. Check the permissions for /usr/local/grass42/locks
   /usr/local/grass42 > ls -la locks/
   total 3
   drwxrwxrwt 4 root root 1024 Apr 14 15:40 .
   drwxr-xr-x 13 root root 1024 Apr 14 15:38 ..
   drwxrwxrwt 2 root root 1024 Apr 14 15:43 ifbo22

It should look like this (with different machine's name certainly)

BTW: Valid are the online instructions. I changed this part of
locks permission settings recently, so it may not be correct in
the instructions included in the Linux package.

4. Check the permissions of your home directory:
   cd $HOME
   akk@ifbo22:~ > ls -la .
   drwxr-xr-x 17 akk users 2048 Apr 14 15:49 .
   drwxr-xr-x 8 root root 1024 Feb 10 19:03 ..

   Here it belongs user "akk", certainly he needs write/read/execute
   permissions (first drwx in line containing ".").

This should be o.k.

   Test it in your home with
    touch .gislock
    rm .gislock

This should work.

-----------------------------
Is there any other user in the list having an idea? I haven't seen
this problem yet in my "GRASS life".

With regards

Markus Neteler

Hallo!

I an quite new to the GRASS 4.2 and espessially to sites and rim.

And i also appologise for my long letter. Sorry but i tried to be
understoodable ..

i got slackware, g77, grass4.2 and rim supposedly set up and working. I
teached also to myself how to use rim separately. And also i read the seeds
tutorial and practically went thru the exercises. So i have a humble
experience

What i am trying to do is like this:

Now, i entered grass with spearfish sampledata and tired figure out how to
use database (with s.db.rim).

First i found out that there isnt any rim databases (s.db.rim -> 2) included
eith spearfish so i decides to create one

I prepared a file 'db1':

.make
~sSite~~~~~~~~~~~~~~~~~~~~
~xX~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~yY~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.end

(last line ends with Return)

and issued at the grass prompt command to make database 'first':

Mapset <root> in Location <spearfish>
GRASS-GRID > s.db.rim first

s.db.rim version 1.4 6/11/91.

The database first does not currently exist.
You must make (.make) it before executing any other commands.

and then:

s.db>.input db1

Input file is changing to file 'db1'.
.make
~sSite~~~~~~~~~~~~~~~~~~~~
~xX~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~yY~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.end

Form Definition Accepted.
Building the RIM database in directory
/usr/local/grass42/data/spearfish/root/rim/sites
sh: data: command not found

Database is now 'made'.

Mapset <root> in Location <spearfish>
GRASS-GRID >

I am worried why it complains about 'data'. should i have that kind of a
shell program, i guess not?

But all right, i continued:

GRASS-GRID > s.db.rim first

s.db.rim version 1.4 6/11/91.
The database first has 0 records.

s.db>.add
add>Site 1
Unknown field name: site.

and here i am stuck

I checked the structure:

s.db>.show

~sSite~~~~~~~~~~~~~~~~~~~~
~xX~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~yY~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

s.db>

And it seem to be all roght, right?

So, i am very interested in getting most out of the grass because the
program feels great. I like this batch mode it supports and the fact that i
got 10 fingers and i can use them in linux Not just fiddling with mouse.

Is there any tutorial or source where i can learn espessially about using
grass vector and sites (inluded rim) capabilities? Like the seeds with lakes
sample database.

Best Regards, Imre Oolberg

PS I confess i haven't yet got the idea what to do with the database if it existed
but it mustnt to be so hard.

BTW, i printed out the Markus Neteler tutorial and several other materials
(like manuals on commands) from the other german site. Did i miss something?
