perl instead of grep 'conversion' help?
Hello:
I butchered a shell script together, but my script kung-fu is 5 years old and all I've used for 5 years are for i loops. I hope that some perl guru can do in 5 minutes what takes me 5 weeks, so I am asking for help.
I have a simple script using "grep -A 2 'string' /path/to/file" but after importing my data into it (if's a FF plugin called ReminderFox), the rows are "re-ordered"
script now outputs: (source ics file is 'US Holidays')
But grep'ing with the same command on my backup file, I get this kind of output:
In simplest terms, my request is...
I'd like to have these fields from any ics file that has them:
SUMMARY:
DTSTART;VALUE=DATE:
DTEND;VALUE=DATE:
(and echo a newline)
and if possible convert DTSTART|DTEND data...
from it's current format of "+%Y%m%d" to "+%h %m %Y"
This is NOT homework.
Bash = GNU bash, version 4.0.38 | Awk = GNU Awk 3.1.7
Grep = GNU grep 2.6.3 | perl = 5.10.0
I hope this is clear.
Thank you for your time.

time::seconds
Time::Seconds(3pm) Perl Programmers Reference Guide Time::Seconds(3pm) NAME
Time::Seconds - a simple API to convert seconds to other date values SYNOPSIS
use Time::Piece; use Time::Seconds; my $t = localtime; $t += ONE_DAY; my $t2 = localtime; my $s = $t - $t2; print "Difference is: ", $s->days, " "; DESCRIPTION
This module is part of the Time::Piece distribution. It allows the user to find out the number of minutes, hours, days, weeks or years in a given number of seconds. It is returned by Time::Piece when you delta two Time::Piece objects. Time::Seconds also exports the following constants: ONE_DAY ONE_WEEK ONE_HOUR ONE_MINUTE ONE_MONTH ONE_YEAR ONE_FINANCIAL_MONTH LEAP_YEAR NON_LEAP_YEAR Since perl does not (yet?) support constant objects, these constants are in seconds only, so you cannot, for example, do this: "print ONE_WEEK->minutes;" METHODS
The following methods are available: my $val = Time::Seconds->new(SECONDS) $val->seconds; $val->minutes; $val->hours; $val->days; $val->weeks; $val->months; $val->financial_months; # 30 days $val->years; $val->pretty; # gives English representation of the delta The usual arithmetic (+,-,+=,-=) is also available on the objects. The methods make the assumption that there are 24 hours in a day, 7 days in a week, 365.24225 days in a year and 12 months in a year.

Please see Time::Piece for the license. Bugs Currently the methods aren't as efficient as they could be, for reasons of clarity. This is probably a bad idea. POD ERRORS
