Re: Error opening a file

Well, that line will not produce that error. We've been through this before, you need to post complete/runnable programs. How (Not) To Ask A Question

$ perl -MO=Deparse,-p -e " my $perl_file = <$dir/scripts/*.pl>
use File::Glob ();
(my $perl_file = glob(($dir . '/scripts/*.pl')));
-e syntax OK

It's a very big program,I am trying my best not to confuse you guys by asking short questions. I have a "Datascript.exe",am running that script and saving it in "$Datafile" variable,after saving $Datafile has 100's of lines but now I want to parse each line using a while loop(any loop for that matter) and am running into the errors mentioned.What is the best way I can parse eachline in $Datafile?Please suggest $Datafile =`Datascript -p=$perl_file`; open $file, '<', $Datafile or die "could not open '$file' $!"; while ( my $match = <$file> ) { } [download]	[reply] [d/l]

You're not trying to open $file, you're trying to open $Datafile $Datafile is not a file only 2 argument open can executes programs, see perlipc Its easier to use one of IPC::System::Simple/IPC::Open2/IPC::Open3...	[reply]

Run this: use strict; use warnings; my $perl_file = WHATEVER_VALUE_THIS_IS_SUPPOSED_TO_BE; my $Datafile = `Datascript -p=$perl_file`; print "Datafile = $Datafile\n"; [download] Is `$Datafile` what you expect? That is, is it the name of the file you expect to open? EDIT: Added `$perl_file =` line.	[reply] [d/l]
