The structure of the paths are like this:
/home/domains/www.domain2.com/tgp/

Hello,
Every time my script runs I want it to go and copy all the files from a remote server directory to my local directory. Whenever I have files in the remote directory the command scp -p $proxy_user@$proxy_server:"$remote_dir/*" ${local_dir}
executes with 0; when I have no files in the... (2 Replies)
I know this is very basic and looks strange to me .

DIFF(3) User Contributed Perl Documentation DIFF(3)NAME
PDL::GSL::DIFF - PDL interface to numerical differentiation routines in GSL
DESCRIPTION
This is an interface to the numerical differentiation package present in the GNU Scientific Library.
SYNOPSIS
use PDL;
use PDL::GSL::DIFF;
my $x0 = 3.3;
my @res = gsldiff(&myfunction,$x0);
# same as above:
@res = gsldiff(&myfunction,$x0,{Method => 'central'});
# use only values greater than $x0 to get the derivative
@res = gsldiff(&myfunction,$x0,{Method => 'forward'});
# use only values smaller than $x0 to get the derivative
@res = gsldiff(&myfunction,$x0,{Method => 'backward'});
sub myfunction{
my ($x) = @_;
return $x**2;
}
FUNCTIONS
gsldiff()
This functions serves as an interface to the three differentiation functions present in GSL: gsl_diff_central, gsl_diff_backward and
gsl_diff_forward. To compute the derivative, the central method uses values greater and smaller than the point at which the derivative is
to be evaluated, while backward and forward use only values smaller and greater respectively. gsldiff() returns both the derivative and an
absolute error estimate. The default method is 'central', others can be specified by passing an option.
Please check the GSL documentation for more information.
Usage:
($d,$abserr) = gsldiff($function_ref,$x,{Method => $method});
Example:
#derivative using default method ('central')
($d,$abserr) = gsldiff(&myf,3.3);
#same as above with method set explicitly
($d,$abserr) = gsldiff(&myf,3.3,{Method => 'central'});
#using backward & forward methods
($d,$abserr) = gsldiff(&myf,3.3,{Method => 'backward'});
($d,$abserr) = gsldiff(&myf,3.3,{Method => 'forward'});
sub myf{
my ($x) = @_;
return exp($x);
}

FUNCTIONS
diff_central
Signature: (double x(); double [o] res(); double [o] abserr(); SV* funcion)
info not available
diff_central does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input
piddles.
diff_backward
Signature: (double x(); double [o] res(); double [o] abserr(); SV* funcion)
info not available
diff_backward does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input
piddles.
diff_forward
Signature: (double x(); double [o] res(); double [o] abserr(); SV* funcion)
info not available
diff_forward does not process bad values. It will set the bad-value flag of all output piddles if the flag is set for any of the input
piddles.
