Best approach for a 10 min extract out of several log files with timestamped records
I have a task where I need to code a shell script to extract a 10 min range (10 min from now until now) extract of a log file.
I taught I could simply use a command that would say something like Start=date - 10 min but I didn't find anything. Looks like the only solution would have to code a small script that would extract the time, strip the values, sub 10 min, check for month and year crossover and convert back into a date string.
Idealy, if there was a command to extract all records from start (chronologicaly reveresed) up until matching record= 10 min back, that would be great. I seriously dought there would be such a thing.
Any suggestions ? I'm a Unix script beginner.

Hi,
I am looking for the syntax to provide a timestamped log_file in expect.
Basically I want the equivalent of:

But scripted in expect so it can be handed over to the logfile function.
