Re^3: reading files from a directory by johngg (Canon) on Oct 28, 2010 at 08:42 UTC
The recommendation these days is to use the three argument form of open, lexical filehandles rather than package filehandles (i.e. `$fh` rather then `IN`) and to check for the success of the operation, showing the O/S error (`$!`) in the error message on failure. `... my $inputFile = q{/path/to/myFile; open my $inputFH, q{<}, $inputFile or die qq{open: < $inputFile: $!\n}; ...` [download] I hope this is helpful.

open my $inputFH, q{<}, $inputFile
   or die qq{open: < $inputFile: $!\n};
