I am newbie to bash scripting. Could someone help me with the following.
I have log file with output as shown below

I' m trying to grep for lines of an output with time >=60ms.

Desired output:

Any ideas how this could best be accomplished?

Try:

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

or something like

awk -Ftime= '$2+0>=60' file

Both worked perfectly for what I needed, thanks!

Hello,

Following may also help.

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

Output will be as follows.

Thanks,

@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..
