Shell Script for Yesterday's Date I'm trying to execute the following shellscript with hazel app on any file in the folder.  It works, but the only thing thats causing a problem is the date for yesterday.

#! /bin/bash

saveDir="TJ"
dd=$(date --date='yesterday' +'%m-%d-%Y')
for file in *.csv ; do
    saveName="${saveDir}/TJ ${dd}.csv"
    cut -d',' -f2,14 "$file" &gt; "$saveName"
done


Any ideas why it isn't working?
Try using date like this:

dd=$(date -v -1d '+%m-%d-%y')


as mentioned yesterday is part of GNU Date, but using an offset of -1d should be equivalent for OS X use.
