This page contains note for users who convert their Bash script to Python.
User break
In Bash:
# what to do in case of user break:
exitprocedure()
{
g.remove rast=$TMP1 > /dev/null
}
# shell check for user break (signal list: trap -l)
trap "exitprocedure" 2 3 15
In Python:
import sys
import atexit
import grass.script as grass
def cleanup():
grass.run_command('g.remove',
rast = tmp1)
def main():
...
return 0
if __name__ == "__main__":
options, flags = grass.parser()
atexit.register(cleanup)
sys.exit(main())
