In other cases, the length limits may apply to particular portions of the filename, such as the name of a file in a directory, or a directory name.A Unixlike kernel is normally neutral about any byte value but \000 (ASCII: NUL) and \057 (ASCII: slash). In Linux, there are no other restrictions at the filesystem layer, but certain FS drivers and certain their modes lead to the rejection of some names, usually due to the impossibility of translation. linux filename characters allowed

For Perl Scripts that lets you know which files linux filename characters allowed Overall this a a tricky area and it seems to get very thorny if you are trying to synchronise a music collection between Windows and Linux wherein certain folder or file names contain funky characters. The safest thing to do is stick to ASCIIonly filenames. Dec 08, 2014 Spaces, and indeed every character except and NUL, are allowed in filenames. As for characters allowed, any byte value is allowed on the ext4 file system, except for the NULL byte (and, as that is the directory separator 1).
