Faster way to use this awk command
Code:
awk "/May 23, 2012 /,0" /var/tmp/datafile

the above command pulls out information in the datafile. the information it pulls is from the date specified to the end of the file.

now, how can i make this faster if the datafile is huge? even if it wasn't huge, i feel there's a better/faster way to get what i want.
