| Observe the following:
|
| $ uname -rs
| FreeBSD 4.1-RELEASE
| $ ls -l
| $ mkdir foo
| $ ln -s foo bar
| $ rmdir bar
| rmdir: bar: Not a directory
|
| So far, so good -- but look at this:
|
| $ rmdir bar/
| $ ls -l
| total 0
| lrwxrwx--- 1 gjb wheel 3 Feb 4 06:35 bar -> foo
| $
for kicks notice the difference between
cp -R foo
and
cp -R foo/
foo doesn't have to be a symlink.
the cp manpage doesn't mention this;
-R If source_file designates a directory, cp copies the directory and
the entire subtree connected at that point. This option also caus-
es symbolic links to be copied, rather than indirected through, and
for cp to create special files rather than copying them as normal
files. Created directories have the same mode as the corresponding
source directory, unmodified by the process' umask.
foo and foo/ both designate a directory (if foo is not a symlink).
thank god for setopt auto_remove_slash in zsh d8)
