Top Forums Shell Programming and Scripting Extracting lines in file based on time Post 302333714 by faelric on Tuesday 14th of July 2009 01:34:08 AM

Currently what i've done is only to retrieve records no later than an hour.
want to extend the feature to include retrieving of records within 15mins of current time. I don't think my current method can be applicable to 15mins intervals..

Code:
 
str=`TZ=GMT-7 date +%b" "%d" "%H:` # this sets a time earlier by one hour.
 
#echo str will give you something like "Jun 18 01:"
 

grep "$str" test.log > new.log  # test.log refers to the file format that i've mentioned earlier.
