## NAME

d.zoom.last.sh - Allows the user to change the current geographic region settings interactively and tracks the last region settings. (An addition to the GRASS display program d.zoom).
(GRASS Shell Script)

## SYNOPSIS

d.zoom.last.sh

## DESCRIPTION

d.zoom.last.sh is a UNIX Bourne shell macro which allows the user to interactively adjust the settings of the current geographic region using a pointing device such as a mouse, and automatically saves the last region settings. The last region can be restored by a GRASS command:

  g.region region=last
or
  g.region last

This script and the above restoring command function as an 'undo' in editing.

## NOTES

Only the last region is saved. When zooming multiple times, regions before the last are NOT available. Region-file 'last' is reserved for d.zoom.last.sh.

## FILES

See the file `$GISBASE/scripts/d.zoom.last.sh`.
