ACLs and cp

[Andreas Gruenbacher]

Dear all,

I have a question concerning the cp utility.

DS17 specifies that these tools retain the ACLs of files. Now how does the umask
affect the behavior (and how does a default ACL)? Should cp simply copy the
permissions 1-1, or should it copy the permissions, minus those masked out by
the umask?

The GNU fileutils do a chmod() with the umask bits masked out after copying:

  > umask
  022
  > ls -l x
  -rw-rw-rw-   1 agruenba users           0 Jan 13 01:00 x
  > cp x y
  > ls -l y
  -rw-r--r--   1 agruenba users           0 Jan 13 01:05 y


Thanks,
Andreas
