It doesn't say which filename/pathname it should apply to in the case of symlinks where both the file and the target of the symlink are listed like in ls -l/-n output.

For symlink in ls -lLF or ls -lLp (without -L/-H), leave it unspecified whether the character is appended to the symlink or its target or both, but when it's to the file, it should be based on the type as obtained from lstat(), and when it's to the target, it should be based on the type as obtained from stat(). For -p, for symlinks to directories, leave it unspecified whether a / is appended, but that if one is appended, it should be to the target of the symlink. IMO, Solaris' ls -lF output of: lrwxrwxrwx 1 chazelas other 4 Jun 15 21:07 fifo-link -> fifo should be considered a bug, I would expect a @ after the link, or | after the fifo (the latter in that case for consistency with the "dir-link -> dir/"). We should probably make it clearer that by "target of the symlink" we mean after *full* symlink resolution (so not the target as in what appears after the "->" which may very well identify another symlink). ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2017-06-15 20:41 stephane New Issue 2017-06-15 20:41 stephane Name => Stephane Chazelas 2017-06-15 20:41 stephane Section => ls utility 2017-06-15 20:41 stephane Page Number => 2923-2927 2017-06-15 20:41 stephane Line Number => 96644,96693,96785->96793 ======================================================================
