ogrmerge.py:tldr:1b869

The command you provided is using the "ogrmerge.py" script, which is a part of the GDAL library. This script is typically used to merge multiple vector layers into a single output file.

Let's break down the command and its arguments:

• ogrmerge.py: This is the name of the script or command that will be executed.
• -f ${GPKG}: This option specifies the output file format. "${GPKG}" is a placeholder that needs to be replaced with the desired format, in this case, the GeoPackage format.
• -o ${path-to-output-gpkg}: This option specifies the output file name and its location. "${path-to-output-gpkg}" is a placeholder that needs to be replaced with the desired output file path.
• ${path-to-input1-shp path-to-input2-shp ---}: These are the input files to be merged. "${path-to-input1-shp}" and "${path-to-input2-shp}" are placeholders that need to be replaced with the paths to the actual input shapefiles. You can add more input shapefiles by separating them with spaces.

To use this command, you need to replace ${GPKG} with the desired output format (e.g., gpkg), ${path-to-output-gpkg} with the desired output file path and name, and ${path-to-input1-shp path-to-input2-shp ---} with the paths to the input shapefiles you want to merge.

Note that you would typically need to have GDAL installed and properly set up on your system for this command to work.
