Created page with "This page contains note for users who convert their Bash script to Python. == User break == In Bash: <source lang=bash> # what to do in case of user break: exitprocedure() { ..."

New page

This page contains note for users who convert their Bash script to Python.

== User break ==

In Bash:

<source lang=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
</source>

In Python:

<source lang=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())
