From the help file, I thought that using the file option will prevent one from hitting open files limit and the size limit of command line arguments. Am I misunderstanding the r.series helpfile?
the file option prevents too long command lines: instead of providing hundreds of map names as input, only one file with the map names is provided the manual is wrong: Use the *file* option to analyze large amount of raster maps without hitting open files limit and the size limit of command line arguments. must be Use the -z flag to analyze large amount of raster maps without hitting open files limit and the *file* option to avoid hitting the size limit of command line arguments.
