Yes, as tjlist said, the percecitonal way really should be
if ( ( system("/bin/chio -f $changerDevice move slot ".($tape-1)." drive 0
") ) / 256 ) {
print "$progname: cannot '/bin/chio -f $changerDevice move' tape
$tape into drive 0\n";
exit(2);
}
print LOG &do_time(), ": leave: Load\n";
And in the first example, the 2nd example would be
sub getDate {
print "start date\n";
my $buff = '';
if ( ($buff = `/bin/date`) eq ''){
print "can't get date\n";
exit(2);
}
print "finish date\n";
}

Hi, I'm trying to do something like this: range= `expr `date '+%m'` - 1` and it does not work. How can I tell it to evaluate an expression within another expression evaluation?

Both of these variables are set inside the script (in fact,... (2 Replies)

Hi all,
Here is my code:

data::faker::datetime
Data::Faker::DateTime(3pm) User Contributed Perl Documentation Data::Faker::DateTime(3pm)
NAME
Data::Faker::DateTime - Data::Faker plugin
SYNOPSIS AND USAGE
See Data::Faker
DATA PROVIDERS
unixtime
Return a unix time (seconds since the epoch) for a random time between the epoch and now.
date
Return a random date as a string, using a random date format (see date_format).
time
Return a random time as a string, using a random time format (see time_format).
rfc822
Return an RFC 822 formatted random date. This method may not work on systems using a non-GNU strftime implementation (kindly let me
know if that is the case.)
ampm
Returns am or pm randomly (in the current locale) using one of the formats specified in ampm_format.
time_format
Return a random time format.
date_format
Return a random date format.
ampm_format
Return a random am/pm format.
datetime_format
Return a random date and time format.
month
Return a random month name, unabbreviated, in the current locale.
month_abbr
Return a random month name, abbreviated, in the current locale.
weekday
Return a random weekday name, unabbreviated, in the current locale.
weekday_abbr
Return a random weekday name, abbreviated, in the current locale.
sqldate

datetime_locale
Return a datetime string in the preferred date representation for the current locale, for a random date.
date_locale
Return a date string in the preferred date representation for the current locale, for a random date.
time_locale
Return a time string in the preferred date representation for the current locale, for a random date.
century
Return a random century number.
dayofmonth
Return a random day of the month.
UTILITY METHODS
Data::Faker::DateTime::timestr($format);
Given a strftime format specifier, this method passes it through to POSIX::strftime along with a random date to display in that format.
Perl passes this through to the strftime function of your system library, so it is possible that some of the formatting tokens used
here will not work on your system.
NOTES AND CAVEATS
Be careful build timestamps from pieces
Be very careful about building date/time representations in formats that are not already listed here. For example if you wanted to get
a date that consists of just the month and day, you should NOT do this:
my $faker = Data::Faker->new();
print join(' ',$faker->month,$faker->dayofmonth)."
";
This is bad because you might end up with 'February 31' for example. Instead you should use the timestr utility function to provide
you a formatted time for a valid date, or better still, write a plugin function that does it:
my $faker = Data::Faker->new();
print $faker->my_short_date()."
";
package Data::Faker::MyExtras;
use base qw(Data::Faker);
use Data::Faker::DateTime;
__PACKAGE__->register_plugin(
my_short_date => sub { Data::Faker::DateTime::timestr('%M %e') },
);
POSIX::strftime
See the documentation above regarding the timestr utility method for some caveats related to strftime and your system library.
