The // prefix is a specific case in point. CIFS/NTFS *does* catch invalid characters... unless the kernel filesystem is buggy, which Linux's has been. Multiple times. The result of that is files that you can write but fail to read back, sometimes on Linux and sometimes on the remote / the Windows dual-boot, as appropriate. Again, this knowledge *should not* be coded into perl; we can't be nannies for Linux filesystem driver developers. -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
