Re^2: Detecting lchown and falling back to chown

The program is supposed to recreate permissions of files. It would be run over both symlinks and non-symlinks, and over non-symlinks any function will do, however for symlinks I would need lchown. So I want my script to have full functionality on systems with lchown and at least partial functionality on systems without it.

However you are right .. I do not really want to even attempt the chown if it is a symlink and I do not have lchown. I guess this would be more appropriate:

 sub best_chown($$$) { 
   chown(@_) unless -l $_[0]; 
 }

Does this make sense?

Messed up the parameter order. Should probably be (I never call it for more than 1 file at a time): `sub best_chown($$$) { chown(@_) unless -l $_[2]; }` [download]	[reply] [d/l]
