What have you tried?

What scripts have you written?

What are you attempts to process this file yourself?
# 3  
i tried with the for loop but it didn't worked for me.i am sorry to say i am not good at AWK. looking for any small script on AWK which will help me so that i posted the question
# 4  
Why those odd numbers, why not 9:00h - 10:00h etc?

Why not midnight till midnight?
# 5  
Actually it is like log from a test run ..so when ever the test run is started, this log will start rolling so cant consider it as midnight till midnight..!
if i can pass the test run starting time as 09:55 so that it should split in to 24 files accordingly
can u help me in this scenario.?

Zeroth approximation - try and see if you can adapt it:

grep -E "2019-05-20 (09:5[5-9]|10:5?[0-4])" file

Might be interesting to see the regex around midnight.

If it was me, who processes text files with PHP, I would do something like this:

use the PHP date function, like so:


// read the file.
// foreach line in the file as entry
// get the formatted date in each entry and convert it to unix timestamp ($timestamp)
$hour = date(h,$timestamp);
// write append entry to 'filename_ '.$hour.'.txt' or whatever you want to call these 24 files.

This is almost trivial in PHP using date().

Hope this helps.

EDIT: See next post for a more complete PHP solution.
