Get yesterday's date or a previous time

date -d '1 day ago'; date -d '11 hour ago'; date -d '2 hour ago - 3 minute'; date -d '16 hour'
With this command you can get a previous or future date or time. Where can you use this? How about finding all files modified or created in the last 5 mins? touch -t `echo $(date -d "5 minute ago" "+%G%m%d%H%M.%S")` me && find . -type f -newer me List all directories created since last week? touch -t `echo $(date -d "1 week ago" "+%G%m%d%H%M.%S")` me && find . -type d -cnewer me I'm sure you can think of more ways to use it. Requires coreutils package.

What Others Think

On Macs, one must use gnu date to get a future or past date.

@stanishjohnd On my linux system and likely on many others, coreutils are GNU utilities. Is that command named differently under OS X?

date -d '52334343 hours ago' Fri Aug 20 21:12:37 PDT 2027 There's a bug either in date, or ubuntu's date :)
