Filename length limits on linux?

Question

Are there any filename or path length limits on Linux?

Answer 1

http://en.wikipedia.org/wiki/Comparison_of_file_systems

See the section called "limits"

Answer 2

And for the sake of saving time (and anchoring it to memory):

ext2, ext3, ext4, zfs: no pathname limits; 255 bytes filename limit.

Answer 3

There I've read that path length limit is in system headers. File name lenght limit is there too. On my system its file

  /usr/src/linux-headers-2.6.38-10/include/linux/limits.h 

and C-lang defines:

  #define NAME_MAX         255    /* # chars in a file name */
  #define PATH_MAX        4096    /* # chars in a path name including nul */

and some more.

Answer 4

Those are file system name lengths. "linux" itself has some too. For instance, from bits/stdio_lim.h:

# define FILENAME_MAX 4096
