Top Forums UNIX for Dummies Questions & Answers Basic loop awk/shell script question.. Post 302902101 by Don Cragun on Sunday 18th of May 2014 04:13:38 PM

Hi pc2001,
Would you please explain what you are trying to do with the following code?:
Code:
        pattern="*${Barcode}*"
        names=`find /Users/pc/test -name "*${Barcode}*"`
        myname=`echo $names | cut -d' ' -f1`

Does dataworksheet.txt contain the final component of pathnames to be copied or is it just a string or pattern that can appear anywhere in the name of a file (including a directory) found anywhere in the file hierarchy rooted in /Users/pc/test?

Given that your destination directory is a subdirectory of the root of your search, do you really want find to include files found in /Users/pc/test/newdata while it is listing matching files found in /Users/pc/test?

       ex. CGI

	 use GD::Barcode::Industrial2of5;

	 die $GD::Barcode::Industrial2of5::errStr unless($oGdBar);     #Invalid Characters
	 $oGdBar->plot->png;

DESCRIPTION

       GD::Barcode::Industrial2of5 is a subclass of GD::Barcode and allows you to create Industrial2of5 barcode image with GD.

   new
       $oGdBar = GD::Barcode::Industrial2of5->new($sTxt);

       Constructor.  Creates a GD::Barcode::Industrial2of5 object for $sTxt.  $sTxt has numeric characters([0-9]).

   plot()
       $oGd = $oGdBar->plot([Height => $iHeight, NoText => 0 | 1]);

       creates GD object with barcode image for the $sTxt specified at new method.  $iHeight is height of the image. If NoText is 1, the image has
       no text image of $sTxt.

	ex.
	 my $oGdB = GD::Barcode::Industrial2of5->new('12345678');
	 my $oGD = $oGdB->plot(NoText=>1, Height => 20);
	 # $sGD is a GD image with Height=>20 pixels, with no text.

   barcode()
       $sPtn = $oGdBar->barcode();

       returns a barcode pattern in string with '1' and '0'.  '1' means black, '0' means white.

	ex.
	 my $oGdB = GD::Barcode::Industrial2of5->new('12345678');
	 my $sPtn = $oGdB->barcode();

   $errStr
       $GD::Barcode::Industrial2of5::errStr

       has error message.

   $text
       $oGdBar->{$text}

       has barcode text based on $sTxt specified in new method.
