in thread permission error

Thank you toolic for your great help although I need to read more about "unless". I am not sure I understand it totally. I tested the script and for some reason it only reads the first text files in the directory (they are all text files). How I can generate a text files in the output for every text files that it reads in?
#!/usr/bin/perl use strict; use warnings; my $dir="C:/move/output/test"; opendir DIR, $dir or die "Unable to open $dir: $!"; while (my $filename=readdir DIR) { my $file="$dir/$filename"; next unless -f $file; open my $fh, '<', $file or die "Unable to open $filename: $!"; open OUT,">C:/move/output/test/out.txt"; select OUT; my (variables); { my loop} close $fh; }

    The code you posted will open every file that exists and passes the -f (entry is plain file) file test.

    Unfortunately, it will also open the same output file on each pass of the while loop -- with write permission (not append). Ie, every pass through the loop creates a completely new c:/move/output/test/out.txt file. I suspect this is the reason you believe you are only finding a single file.

    To append to the file on each pass, change your open command from open OUT,">C:/move/output/test/out.txt"; to open OUT,">>C:/move/output/test/out.txt"; You should also consider checking the return value of open.

      Thank You!
