O Wise Ones,

(Slap me twice for this one--got my operating systems mixed up!)

This is one of those silly moments when I can't remember a simple trick,
and I'm too cotton-pickin' lazy to dig through all my Perl books to find
it. I'm maintaining some old DOS code that has pathed Linux filenames
suffering from LTS. you know...
\/usr\/local\/fardle\/whang\/dang\/doodle\/etc.....

I know there's a way to eliminate all that \/ stuff, but I can't think of
it to save my life. I'll gladly accept a Gibbs head-slap (for all you
fellow NCIS fans out there), if it's accompanied by the solution.

Thanks!

I thought perl always accepts the forward slash, regardless of operating
system. "c:/temp" works in windows/dos.

Not sure what you mean by eliminate them. Couldn't you just use an
editor to change them to /?

In what context do you think you need those backslashes?

In a regular string, you can do 'foo/bar/baz'.

In a regex, you can use the special quoting construct:
$_ =~ m{/foo/bar/baz};

Re: "Leaning Toothpicks" across OSs

I agree. Yeah, you could put a regex like

s{\\}{/}gmx

in there, but I'd fix it not work around it.

RE: "Leaning Toothpicks" across OSs

If you really need things to work across different OS, use the
File::Spec module. It's great for platform independent Perl code.
Here's a quick example.

use File::Spec;
my $file = File::Spec->catfile (qw (usr, localfardle whang dang doodle
extc));
print "File: $file\n";

Prints:
File: usr/localfardle/whang/dang/doodle/etc

Which is close.
my $file = File::Spec->catfile ("", qw (usr, localfardle whang dang
doodle extc));

Will put in the leading "/". But there are probably other options that
will force it to put in an absolute path.

There are also other options available if you want to use non-native
file spces. See the docs for this module.
