Hi,
suppose I have the following symlink in my $HOME
etcetera -> /etc
. Is there a way to get back "/etc" only (not the contents
of /etc/. nor "etcetera") when doing a 'ls' or such?
Thank you very much in advance for any help!
Best regards,
mcc

The not-specific-to-zsh bit:
$ ls -Lld etcetera
The -L says to chase the symlink when given on the command-line. You
then want -d to not list the contents of the directory, only the
directory itself.
The options require vary by command used.
For the zsh "zstat" module-provided builtin, "zstat -L" will give you a
"link" field.
% zstat -L +link etcetera
/etc

Depends on what is covered by "or such" ...
% zmodload zsh/stat
% zstat +link etcetera
/etc
However, that prints nothing if the file is not a symbolic link.
I don't know of any external utility that will print *only* the target
of the symlink. E.g.
% /usr/bin/stat --format=%N etcetera
'etcetera' -> '/etc'

readlink(1) is part of GNU coreutils and is part of the base system on
FreeBSD, OpenBSD, etc.
% readlink etcetera
/etc
(On FreeBSD, at least, it's a hardlink to the stat(1) command, which
switches behaviour if argv[0] shows it was invoked as readlink.)
