# for loop to list a set of text files specified in the input directory
# The script is set up to only process files in the input directory which start with "1", "b" or "r" and end in ".txt".  If you would like to process all text files in the specified input directory, change the beginning of the for loop below to: for i in `ls $inputdirname/*.txt

for i in `ls $inputdirname/[1br]*.txt`

    # each file is then geo-parsed and the output is written to the output directory
