Get date one month from today

Shell Programming and Scripting

I need to get the date one month in the future from today - or 30 days from today etc...

I need this to work all year around - I cannot find anything to solve this issue in the search / faqs etc....

Its okay - just found I can use something like the below

curmth=`date +%m`
set -A mth 01 02 03 04 05 06 07 08 09 10 11 12
nextmth=${mth[$((curmth))]}
echo $nextmth

curday=`date +%d`
curyear=`date +%Y`

todaynextmonth=$curyear$nextmth$curday
echo "todaynextmonth is $todaynextmonth"

Your script doesn't work in December.

Did you actually look in the FAQ section? http://www.unix.com/answers-frequently-asked-questions/13785-yesterdays-date-date-arithmetic.html

Using the --date option lets You chose how You want it

date --date='1 month'
date --date='10 days ago'

hi Lakris i don't think all unix has that --date option
because AIX don't have any such option...
