Re: [PLUG] Shell script quickie: yesterday's date

[epike@isinet.com]

after typing around I'm surprised that this actaully worked:

localhost.localdomain[119]% date --date=now
Mon Mar 25 14:40:01 EST 2002
localhost.localdomain[120]% date --date=yesterday
Sun Mar 24 14:40:05 EST 2002
localhost.localdomain[121]% 

localhost.localdomain[121]% date --date=yesterday +%Y%m%d
20020324
localhost.localdomain[122]%
