Get all lines in a file after particular time
Hi All,

I am lookig for a way to get all the lines from a log file which has been updated 5 mins prior to the system time.

The log file will be like below:

09:01:00 Started polling
09:01:05 Checking directory test
09:02:00 Error! Cannot access directory test
09:03:00 Polling


I get the system time and calculate 5 mins before the system time. For example if the system time is 09:05, then the script will calculate the time to check as 09:00. Then a sed command will be run to get all the lines below the pattern:

sed '/$time/,$p' $logfile

Which will print all the lines below the pattern. But if the log file does not contain 09:00, no lines will be grepped. Is there a way to solve this issue?

Thanks
D
