Can anyone please tell me how to sort dates and times in unix? Also the difference between sed and awk. thank you.

ls -lst

will produce a list of files sorted by decending time stamps.

The "-M" flag for sort will allow you to treat a field as months.

What do you have to sort?

Similar problem to ask help with ^^;

If I have a table of schedules and the fields are:

date activity timestart timeend

And I use awk '/03-feb-2002/' myfile to list my activities for that certain date:

1. how can i sort it so it shows my activities so that the earliest ones show first and then the later ones?

2. how can i make it so that if i supply an argument (let's say a start time), then the result would be all activities starting from that time onwards

3. how can i make it so that if i supply an argument (a range of time) Ex: 10:00am 11:00am (from 10am-11am), then it shows activities falling under there.

Thanks for any help on this!
