The script dumps time series data from a single grid cell in a gridded output file and then calls a program to
change the format of each and then to combine all the days into one csv file. I'm new to bash and I'm sure there are
some more efficient ways to write the script, so any constructive criticism in that regard would be appreciated.

But what I mean by "not working" is that when I try to run it in the background using the ./[scriptname]& or ./[scriptname] &, everything still runs on the terminal and crowds screen as if I had run it without the &. I had assumed running in the background meant that it would leave the command line free so that I could continue working while it ran. Am I incorrect in my understanding? Thanks in advance for any feedback.
