[GRASS-user] shell scripting problem

[Kirk Wythers]

Thanks Stephen

I just found the problem… bloody meta character "^M" that did not show up in my text editor. I opened the coords file with vi and there it was!

However, today I notice that it is returning fewer data points from my climate data than the number of coordinates that I am querying. For example I have a file "coords" that contains 8973 lines of coordinates. This should return 8973 lines of data from grass. However, the script is returning 8925 lines of data. I'm not getting any errors and can think of no reason the script should behave this way.
