In addition to reading arguments from the command line, GPSBabel can read directions from batch (or command) files via the -b option.

Here is an example demonstrating segmenting a large command line by placing the input and filtering directives in a file called 'all_my_files'.

gpsbabel -b all_my_files -o gdb -F all_my_tracks.gdb

'all_my_files' could look like this:
