[GRASS-dev] File based GRASS batch processing?

[Hamish]

suggested improvements attached:

+ force text mode (don't launch gis.m).
  (probably it should exit with error if MAPSET is not given on command line
   & GRASS_BATCH_JOB is defined, too. so avoid "$ETC/set_data". Or create new
   GRASS_GUI value "none", set if BATCH is used?)

+ replace final "exit 0" with "exit $EXIT_VAL" so the whole grass-batch
command exits with the return value of the batch script, not hardcoded
value "0".


bug:

- your hack fails in Cygwin due to init.sh "if [ "$CYGWIN" ] ; then
  ... export SHELL=" hack earlier in the script


simplify $GRASS_BATCH_JOB to $GRASS_BATCH?
JOB implies ^Z, fg, bg, PID, ...
