How to get a previous date in bash (linux)
Simply put
date -d '1 day ago' +'%Y-%m-%d' # For multiple days date -d '7 days ago' +'%Y-%m-%d'
If you wish to place in a shell script:
RMDATE=$(date -d '7 days ago' +'%Y_%m_%d')
will place for example ‘2013-07-01’ in the RMDATE variable which of course you can use like
echo $RMDATE
