hi,
I am using this to get previous month
`date -d"1 month ago" "+%m"`
But will it work for january?..will it return 12?
Please advice.
date "+%m" | awk '{if($1==01){print 12}else{print $1-1}}'
If I run the following in march I get 12:
% date -d"3 months ago" "+%m"
12
So, I suppose so your command will work for you
