[GRASSLIST:4754] RE: batch jobs

[Daren Zywicki]

Martin,

There are two ways I know of to do this in a script file.  I would 
recommend doing a search on the web for bash programming to get more 
information about bash script loops:

Disclaimer:

expressed or implied, including, but not limited to, the implied warranties 
of merchantability and fitness for a particular purpose.  The ENTIRE risk 
as to the quality and performance of the code is with you.  Should the code 
prove defective, you assume the cost of all necessary servicing, repair or 
correction.


1.) Use a listing of files in a particular directory in a for loop (bash 
syntax shown for *.txt files):

for f in <path to files>/*.txt; do

     echo ${f}
     ... commands for file ${f}

done

2.) Use an input file in a while loop with the piping capabilities of unix 
(as shown below in bash syntax):

while read list1; do

    ... commands for ${f}

done < path to file containing list of maps to process/map_list.txt

where list1 refers to the current input file listed in the map_lists.txt file.


You'll probably have to play around to get things to work, but I hope this 
helps.
