# This script runs grass commands (via stdin) XOR scripts (via $1) inside
# GRASS shell environment.
# Note: It's assumed, that you've set the variables GISBASE, GISDBASE and
#       LOCATION_NAME properly in the run-up to this script.

# set environment variables:

export SHELL_LOCK=$$
export PYWMS_TMP_PREFIX="pywmstmp-"
export SHELL_TMPDIR="/tmp/${PYWMS_TMP_PREFIX}${SHELL_LOCK}"

# if no argument ($1) available, scan stdin:
if [ "$1" == "" ]; then
  # get commands from stdin pipe and execute them in a subshell:
  cat /dev/stdin | /bin/bash
else
  # get script name or command via argument/parameter ($1) and run it:
  $1
