I'm no expert with awk, but here's something i'd like to share:
While i do agree that one-liners are cool, there are occasions it just makes no sense.
Saying, a well formated code is easier to read - and find issues/improvements, than within a one liner of that length. (me have FHD (1920x1080) display, and i need to scroll sideways)
This said, you might want to use a function (rather than an if-block) to transform time and date to seconds and to avoid things like:
For which you could have just written +0.
Once you transformed the date+time to seconds, you simply subtract the one from the other and get the difference.
Hi,
Can someone guide me to write a unix script for getting a hour out of a date command and validating hour to see if its > 7 and < 16. if hours is >7 and <16 then assign a variable value of 0730 and if hour is >16 then assign a variable value of 1630?

Hello,
I've created the script below to compare the content of two files with a delay of an hour. After an hour, the lines that exist in both files, will be printed and executed.

ddate
DDATE(1) Emperor Norton Utilities DDATE(1)NAME
ddate - converts Gregorian dates to Discordian dates
SYNOPSIS
ddate [+format] [date]
DESCRIPTION
ddate prints the date in Discordian date format.
If called with no arguments, ddate will get the current system date, convert this to the Discordian date format and print this on the stan-
dard output. Alternatively, a Gregorian date may be specified on the command line, in the form of a numerical day, month and year.
If a format string is specified, the Discordian date will be printed in a format specified by the string. This mechanism works similarly to
the format string mechanism of date(1), only almost completely differently. The fields are:
%A Full name of the day of the week (i.e., Sweetmorn)
%a Abbreviated name of the day of the week (i.e., SM)
%B Full name of the season (i.e., Chaos)
%b Abbreviated name of the season (i.e., Chs)
%d Ordinal number of day in season (i.e., 23)
%e Cardinal number of day in season (i.e., 23rd)
%H Name of current Holyday, if any
%N Magic code to prevent rest of format from being printed unless today is a Holyday.
%n Newline
%t Tab
%X Number of days remaining until X-Day. (Not valid if the SubGenius options are not compiled in.)
%{
%} Used to enclose the part of the string which is to be replaced with the words "St. Tib's Day" if the current day is St. Tib's Day.
%. Try it and see.
EXAMPLES
% ddate
Sweetmorn, Bureaucracy 42, 3161 YOLD
% ddate +'Today is %{%A, the %e of %B%}, %Y. %N%nCelebrate %H'
Today is Sweetmorn, the 42nd of Bureaucracy, 3161.
% ddate +"It's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H" 26 9 1995
It's Prickle-Prickle, the 50th of Bureaucracy, 3161.
Celebrate Bureflux
% ddate +'Today's %{%A, the %e of %B%}, %Y. %N%nCelebrate %H' 29 2 1996
Today's St. Tib's Day, 3162.
BUGS ddate(1) will produce undefined behaviour if asked to produce the date for St. Tib's day and its format string does not contain the St.
Tib's Day delimiters %{ and %}.
NOTE
After `X-Day' passed without incident, the Church of the SubGenius declared that it had got the year upside down - X-Day is actually in
8661 AD rather than 1998 AD. Thus, the True X-Day is Cfn 40, 9827.
