Re^2: Collapsing paths

canonpath in File::Spec seems to do the trick.

Did you try it out?

#!/usr/bin/perl

use File::Spec;

print File::Spec->canonpath("foo/../bar/../baz/")."\n";
[download]

Output:

foo/../bar/../baz
[download]

I guess not. Did you read the docs? Quote:

Note that this does *not* collapse x/../y sections into y. This is by design.

I guess not.

All dogma is stupid.

Depends on your system. `use File::Spec; print File::Spec->canonpath("foo/../bar/../baz/")."\n";` [download] `\baz` [download] On system without symlinks, `canonpath` collapses `x/../y` (although not always correctly, as shown above). Update: Technically, NTFS does have symlinks, but most software act as if they don't exist, including File::Spec.	[reply] [d/l] [select]

Did you try it out? Yes I did. That's why I wrote "seems". I didn't know the behaviour was platform dependant. The documentation for File::Spec is contradicting the File::Spec::Win32 documentation which specifically says "foo/../bar" will become "bar". lodin	[reply]
