How to grep for a previous day

[chanman525]

Probably a simple solution but I can't find any documentation on it.

I'm trying grep for a previous day using date ="%a %h %d" format. It displays Thu Mar 15.

All I need to do is go back one day. Can anyone put me in the right direction?

Hi,

Have a look at FAQ :

[RodKnowlton]

perl -MPOSIX -e 'print POSIX::strftime("%a %h %d",
                             localtime(time - (3600*24)))'

Will give you yesterday's date in the form you want.
