Hi,

I am using Grass GIS

I have written a script which outputs a list of numbers to a file

code snippet:
r.stats -1 fs=, input=Bones_AVE > /home/gary/AVE_monte_carlo/rstats_AVE$i.csv

so this makes acsv file with one column.
I want to run it again but rather than outputing to a new csv i want to add it to this one as the next column. For this example there will be 100 rows per column.

the 1st one will make the file

[grassGIS code]> /home/gary/AVE_monte_carlo/rstats_AVE.csv
add ',' after each value
the next one

[grassGIS code] open file /home/gary/AVE_monte_carlo/rstats_AVE.csv
add ',' after each value


and so one

My linux is very rusty can anyone help?

Thanks

Gary

Hi, welcome to LQ!

I can't think of a method completely avoiding a temporary file given
the nature of the operation ...
Something like that should work.
