[GRASS-user] why is v.build.all (and many others) a windows batch file and not an executable?

[Bartolomei.Chris]

Hi Martin
The problem I am having is that my bourne shell scripts (#!/bin/sh) cannot execute the bat files ... the scripts call the GRASS modules by name i.e.
v.db.update map=stream_7 layer=3 column=block_col value="-1" --quiet
In GRASS 6.4.4 (with msys) I could just run the scripts and everything ran fine.
I've upgraded to 7.0.4 (from OSGEO4W and with msys) and now my scripts crash any time it tries to execute a GRASS module that is a bat wrapper saying it can't execute them.
The error message is sh: v.db.update: command not found
There is no v.db.update.exe ... only v.db.update.bat ... and, of course, v.db.update.py in the scripts directory.
I have to code it as this now:
python $PY_SCRIPTS/v.db.update.py map=stream_7 layer=3 column=block_col value="-1" --quiet
(where PY_SCRIPTS is the path to the scripts, not the bat wrappers... i.e. c:/OSGEO4W64/apps/Grass/Grass-7.0.4/scripts)

Note that v.db.update is just one of numerous examples ... I tried to attach the list but it bounced.

I understand that some of this is written in C and some of this is written in python ... is it not possible to compile the python into an executable binary (.exe) and just have .exe's in bin?
That would sure save some grief ...
Thanks

> I attached a couple txt files (I hope they don't get striped off...) listing the GRASS modules in the "bin" directory - one lists all of the ".exe" modules and one lists all of the ".bat" modules. Why are there both formats? How are we supposed to run (shell) scripts calling the modules? It just doesn't make sense having the two different formats in the same folder... all of the modules should be executables or all of the modules should be Windows Batch files. Having the mix makes it very hard to program.

sorry I don't fully understand your question. The `bin` directory
contains executables, in other words programs (modules) which are
added to the PATH when GRASS is starting. The exe files are binary
executables (compiled C modules). The bat files are wrappers around
Python modules (same as it was in GRASS 6 for Bash modules). Martin
