in reply to Newlines: reading files that were created on other platforms

When reading text of an unknown source that is likely to mix line endings (I find this in the html source of quite a few websites and in WinNT error messages), I tend to preprocess with "tr/\15\12/\n/s;" and then carry on as if nothing was amiss. This does, however, depend _entirely_ on what you want to do with the rest of the data. To demonstrate its usefulness...
#!/usr/bin/perl -w use strict; use Data::Dumper; $Data::Dumper::Useqq = 1; my $text; my @e = ("\012", "\015", "\012\015", "\015\012"); $text .= "this is the line ". ($_ + 1) . $e[$_] for (0..$#e); print "Before: ". Dumper $text; $text =~ tr/\15\12/\n/s; print "After: ". Dumper $text;
Good luck.
