Removing Columns From ALL CSV Files in Specific Folder Then Outputting File With Date

Question

I'm trying to automate some processes by using hazel app to move a file to a specific folder, execute a shell script on any csv in that folder, and then move it to another folder. Right now the part I'm working on is the shell script. I have been testing out the cut command in terminal on csvs but I'm not sure if its the same thing as a shell script since it doesnt seem to be working but what I have is:

cut -d',' -f2,12 test.csv > campaigns-12-31-13.csv

It looks for test.csv but I would like it to work with any csv, and it also exports it with the date 12-31-13 but I'm just trying to get it to export with whatever yesterdays date was.

How do I convert this to a shell script that will execute on any csv in the folder and so it adds the date for yesterday at the end of the filename?

You can try the following script:

#! /bin/bash

saveDir="saveCsv"
dd=$(date +%Y-%m-%d -d "yesterday")
for file in *.csv ; do
    bname=$(basename "$file" .csv)
    saveName="${saveDir}/${bname}-${dd}.csv"
    cut -d',' -f2,12 "$file" > "$saveName"
done
