Assume that current date is mar 9 , i want to keep this as original by keeping 5 days (mar 4- mar8) both .log and .csv as .gz files.
created conf file in /etc/logroatate.d/sqlchck as
/var/log/.log /var/log/.csv {
daily
rotate 5

I want to display like pivot table format.
when im select month and year and check that month and year in database.if yes display values like this pivot table form
eg:july 2015
studid date1 date2 date3..date13 date14 date15 date16 date17.....date31
28 x 1 x 1 1 1 0 1 x x x..x
31 x 1 x 1 1 1 1 1 x x x..x
32 x 1 x 1 1 1 1 0 x x x..x
my controller code is
$amonth = Input::get('amonth');
$ayear = Input::get('ayear');
$dayCount = date('t', strtotime('01-'. $amonth . '-' . $ayear));
$days = [];
for($i = 1; $i <= $dayCount; $i++) {
$days[] = $i; }
$attendence_tbl = WysAttendancename::where('cls_id',$id)->first();
$wys_attendence_table = $attendence_tbl->attendance_name;
$attendance = DB::table($wys_attendence_table)
->where('amonth','=',$amonth)
->where('ayear','=',$ayear)
->get();`
my view .blade.php
<td>Teacher Name</td>
#for($i = 1; $i <= $dayCount; $i++)
<td>{{$i}}</td>
#endfor
</tr>
#foreach($teacher as $teachers)
<tr>
<td>{{$teachers->tname}}</td>
#foreach($attendance as $attendances)
#if($teachers->id == $attendances->t_auserid)
#if($attendances->t_attendance == 1)
<td><font color="green">p</font></td>
#elseif($attendances->t_attendance == 0)
<td><font color="red">a</font></td>
#endif
#endif
#endforeach
#endforeach
its work fine but problem is couldn't check the month day(eg :adate-2) is in exist in database or not .
iam using display full month in column ,code is
$dayCount = date('t', strtotime('01-'. $amonth . '-' . $ayear));
$days = [];
for($i = 1; $i <= $dayCount; $i++) {
$days[] = $i; } `
in my database 1/07/2015 is not but in view page display 2/70/2015 value in 1/07/2015 and also 13/07/2015 value in 3/107/2015 ...
I want to dislpay like above pivot table form
how to change my code to check databse adate and month day($i)???
I'm trying to pipe several perl programs together, and from everything I've read, piped programs are supposed to all open and run in parallel. That doesn't appear to be the case with whatever it is that I did. Here is the simplified version:
./video
#!/usr/bin/env perl
my $i = 0;
while($i<10){
my $time = localtime(time);
print "VID: $time $i\n";
sleep 1;
$i++;
}
./controller
#!/usr/bin/env perl
while(my $line = <STDIN>){
my $time = localtime(time);
print "CTRL: $time $line";
}
./pipes
#!/usr/bin/env perl
open(my $controller, "|./controller") || die "Can't fork: $!";
open(STDOUT, ">&", $controller);
open(my $video, "|./video") || die "Can't fork: $!";
print STDERR "All processes started\n";
I tried executing it two ways, but both resulted in the same output:

The timestamps from the video program increment as they should, but the time that the control program receives them is identical (after the video program has ended). How do I make the controller receive the data as it is produced instead of after the fact?
It's because of STDOUT buffering in the video program. print is line-buffered only if it goes to an interactive terminal. Otherwise it uses a much bigger buffer, and the accumulated output is emitted in one big chunk when video exits. Try flushing after each print or use autoflush.
$| = 1; # Enables autoflush
By the way I don't get why you open a pipe TO video, it does not read anything. It should be
system "./video";
If you have a program that you can't modify but does not autoflush, you are in trouble. Except, you're not. You can use a pseudoterminal instead of a pipe. I've never done it. But chapter 64 of the book "The UXIX Programming Interface" is about pseudoterminals.
So I would like to use function localtime(), but I'm having problems with getting first and last day of last month properly. Right now I have working functionality, but I bet there is a better way to solve this.
use Time::Piece;
use Time::Seconds;
$start_of_month = localtime();
while($start_of_month->mday < 10) {
$start_of_month += ONE_DAY;
}
$start_of_month -= ONE_MONTH; # Subtract one month to get previous month. "ONE_MONTH" is defined by Time::Seconds
$end_of_month = $start_of_month; # Copy start_of_month to end_of_month as they both have same year and month.
# Subtract day from $start_of_month until mday is the first day of the month.
while($start_of_month->mday != 1) {
$start_of_month -= ONE_DAY;
}
# Silly workaround to bring $end_of_month to last day of the month as Time::Piece object does not have good way to change mday.
while($end_of_month->mday != $start_of_month->month_last_day) {
$end_of_month += ONE_DAY;
}
$period_start = $start_of_month->dmy("."); # End result has to be same!
Can anyone give me a better way of handling this?
Don't rely on Time::Piece and constants in Time::Seconds for date manipulation
The following was my suggested simplification of the OP's date manipulation using Time::Piece and Time::Seconds. IF this worked on overloaded operators, it might actually work as intended, but as ikegami pointed out, this isn't guaranteed. So I tested below.
If you want to go the math route, at least you could simplify things a little:
use strict;
use warnings;
use Time::Piece;
use Time::Seconds;
my $date_start = localtime();
$date_start -= ONE_MONTH;
$date_start -= ($date_start->mday - 1) * ONE_DAY;
my $date_end = $date_start + ($date_start->month_last_day - 1) * ONE_DAY;
print $date_start , "\n"; # Prints Mar 1st (at least today it does)
print $date_end , "\n"; # Prints Mar 31st
I'd consider using a different module for this, like Date::Calc or DateTime, but this might work for your purposes.
Testing the above solution - many failures
I created a script the below script that loops through every date for a year starting at January 15th, showing every range where the above code does not work as expected.
use strict;
use warnings;
use Time::Piece;
use Time::Seconds;
my $t = 1389812400; # Wed 2014-Jan-15 7pm GMT. 11am PST
my $t_max = 1421348400; # Thu 2015-Jan-15 7pm GMT. 11am PST
my %prev_month = map {$_ => ($_ - 1) || 12} (1..12);
my $fail = '';
while ($t <= $t_max) {
$t += 60; # Increment by 1 minute
# Testing potentially overloaded math of Time::Piece & Time::Seconds
my $start = my $src = localtime($t);
$start -= ONE_MONTH;
$start -= ($start->mday - 1) * ONE_DAY;
if ($start->mon != $prev_month{$src->mon}) {
print "From ($t) $src -> $start\n" if !$fail;
$fail = " To ($t) $src -> $start\n\n";
} elsif ($fail) {
print $fail;
$fail = '';
}
}
The below is the output of this script with comments inserted to explain why each range fails:
# ONE_MONTH is exactly 2_629_744 seconds, or 30.437 days.

Alternative using Time::Piece->add_months? Nope
Time::Piece has two functions, add_months and add_years intended for date calculations. Unfortunately, the documentation states:
Note that there is some "strange" behaviour when adding and subtracting months at the ends of months. Generally when the resulting month is shorter than the starting month then the number of overlap days is added. For example subtracting a month from 2008-03-31 will not result in 2008-02-31 as this is an impossible date. Instead you will get 2008-03-02. This appears to be consistent with other date manipulation tools.
The below code fully demonstrates this behavior for the timezone PST.
use strict;
use warnings;
use Time::Piece;
my $t = localtime(1420012800);
print $t->add_months($_),"\n" for (0..12)
Output:
Wed Dec 31 00:00:00 2014
Sat Jan 31 00:00:00 2015

Now, it is kind of nice how this function is able to accurately cycle back to the same date a year later, but there are lots of unfavorable months until then.
Conclusion
The constants in Time::Seconds are just that, constants. They are exact numbers of seconds meant to represent periods of time. There is no operator overloading to facilitate fancy date manipulation. Instead, these values are simply good for mathematical comparisons.
To manipulate specific dates, I'd advise using Date::Calc, DateTime, or any of the other modules suggested in this question.
A less OO, but alternate solution:
use POSIX qw(mktime);
my #now = localtime;
# mday = 1, month = month - 1
my $date_start = mktime(#now[0 .. 2], 1, $now[4] - 1, #now[5 .. 8]);
# mday = 0, the 0th day of this month == last day of prior month
my $date_end = mktime(#now[0 .. 2], 0, #now[4 .. 8]);
print scalar localtime $date_start, "\n";
print scalar localtime $date_end, "\n";
This hiccups with daylight saving time; if you don't care about time-of-day you could set $now[2] to 12 noon and hope no country declares night to be day and day to be night:
my #now = (0, 0, 12, (localtime)[3..8]);
I don't trust code that uses Time::Piece. It relies on overloading operators to make it look like you're doing it wrong ($time += ONE_DAY; looks like you're adding a constant) when you're actually doing it right. Maybe. It's hard to tell. You must have intimate knowledge of the guts of the module to know if you're doing it right.
DateTime solution:
my $dt = DateTime
->now( time_zone => 'local' )
->set_time_zone('floating') # Do this when you want to date arithmetic.
->truncate( to => 'day' );
$dt->set( day => 1 )->subtract( days => 1 );
my $last = $dt->ymd('-');
$dt->set( day => 1 );
my $first = $dt->ymd('-');
say "$first .. $last";
Using the Time::Seconds definition of ONE_MONTH gives you a solution that is wrong for several days a year. It is the average length of a month in seconds, and is equal to about 30.4 days. Subtracting that from 1 March, for instance, gives you a date in late January.
However the first day of the previous month can be calculated simply from the month and day fields returned by localtime. Converting this into a Time::Piece object lets us calculate the last day of the same month.
use strict;
use warnings;
use Time::Piece;
my ($m, $y) = (localtime)[4,5];
$y += 1900;
if ($m == 0) {
$m = 11;
$y -= 1;
}
my $period_start = sprintf '%02d.%02d.%04d', 1, $m, $y;
my $period_end = do {
my $tp = Time::Piece->strptime($period_start, '%d.%m.%Y');
sprintf '%02d.%02d.%04d', $tp->month_last_day, $m, $y;
};
print $period_start, "\n";
print $period_end, "\n";
output
01.03.2014
31.03.2014
Sorry if I did not understood property but: DaysInMonth (check coment)
my #monthDays= qw( 31 28 31 30 31 30 31 31 30 31 30 31 );
sub MonthDays {
my $month= shift(#_);
my $year= #_ ? shift(#_) : 1900+(localtime())[5];
if( $year <= 1752 ) {
# Note: Although September 1752 only had 19 days,
# they were numbered 1,2,14..30!
return 19 if 1752 == $year && 9 == $month;
return 29 if 2 == $month && 0 == $year % 4;
} else {
return 29 if 2 == $month and
0 == $year%4 && 0 != $year%100 || 0 == $year%400;
}
return $monthDays[$month-1];
}
If you wish easy data to seconds then take look Time::Local
$time = timelocal( $sec, $min, $hour, $mday, $mon, $year );
I like to have a running ping that only prints output while passing a threshold value.
And if passing this value, also add date to the output.
Here is what I have tried:
ping 8.8.8.8 | awk '{split($7,a,"[=.]");if (a[2]>58) print a[2],d}' d="$(date)"
ping 8.8.8.8 | awk '{"date"| getline date;split($7,a,"[=.]");if (a[2]>58) print a[2],date}'
Problem with both of these is that date is not updated. All is printed with same date.

I know this could be solved using a bash script, but I just like to have a simple command line when testing line ping time.
The following works for me. I'm using OSX Mavericks:
ping 8.8.8.8 | awk -F"[= ]" '{if($10>50) {cmd="date"; cmd | getline dt; close(cmd) ; print $10, dt}}'
This will output the ping line for times > 50 ms.
I get this sample output:
51.352 Fri Nov 15 00:33:40 PST 2013
50.519 Fri Nov 15 00:33:42 PST 2013
52.407 Fri Nov 15 00:33:44 PST 2013
50.904 Fri Nov 15 00:33:50 PST 2013
52.864 Fri Nov 15 00:33:54 PST 2013
When you say:
ping 8.8.8.8 | awk '{split($7,a,"[=.]");if (a[2]>58) print a[2],d}' d="$(date)"
the variable d is evaluated only once due to which you get the same timestamp appended to all the lines in the output. You could instead use strftime as an argument to print:
ping 8.8.8.8 | awk '{split($7,a,"[=.]");if (a[2]>58) print a[2], strftime()}'
