I found a new way to show yesterday. Share to everyone.

awk 'BEGIN{ yesterday=strftime( "%y%m%d", systime()-24*60*60 ); print yesterday}'

with function strftime(), you can customize the time.

for example, if you need show 2 hours ago:

awk 'BEGIN{ t=strftime( "%y%m%d %H%M", systime()-2*60*60 ); print t}'
