Try:
Code:
grep -E 'time=([0-9]{3,}|[6-9][0-9])ms' file

or something like
Code:
awk -Ftime= '$2+0>=60' file

Hello,

Following may also help.

Code:
awk '!/\=[6-9][0-9]/ {next}1' file_name


Output will be as follows.

Code:
11/20/2013  9:11:23.64 Reply from xx.xx.xx.xx: bytes=32 time=62ms TTL=125
11/20/2013  9:11:23.64 Reply from xx.xx.xx.xx: bytes=32 time=78ms TTL=125
11/20/2013  9:11:23.64 Reply from xx.xx.xx.xx: bytes=32 time=60ms TTL=125


Thanks,
R. Singh

@ravinder: that would be equivalent to awk '/\=[6-9][0-9]/' . It would not work for values that are >=100 and also the value of TTL could distort the outcome..
