This question talks about finding directories in a current diretory. The solution is basically:

ls -d */

That's great but how can I easily list symlinks? Do I have to use something like

find . -xtype l -d 1
(intended to find symlinks max depth 1 - doesn't work)

Or is there an easier way? Can ls be used for this?

  • On my Ubuntu system, a quick look at its `man find` shows that `-d` is a synonym for `-depth` (for compatibility with FreeBSD, NetBSD, MacOS X and OpenBSD.), ie. it is not the same as `-maxdepth` . . . `-depth` *Process each directory's contents before the directory itself* – Peter.O Oct 04 '11 at 04:04

In zsh (add N inside the parentheses to include symlinks whose name begins with a .):

echo *(@)

With most find implementations:

find -maxdepth 1 -type l

POSIX-compliant:

find . -type d \! -name . -prune -o -type l -print

Or with a shell loop:

for x in * .*; do
  if [ -h "$x" ]; then echo "$x"; done
done

    For the `-prune` option, you need to use `find topdir ! -name topdir -prune`; otherwise the starting directory is ignored as well. – Arcege Oct 04 '11 at 10:55

This isn't on a Mac, but

find . -maxdepth 1 -type l

works for me.

You should be using -type and not -xtype:

   -xtype c
          The same as -type unless the file is a symbolic link.  For  sym‐
          bolic  links:  if the -H or -P option was specified, true if the
          file is a link to a file of type c; if the -L  option  has  been
          given,  true  if  c is `l'.  In other words, for symbolic links,
          -xtype checks the type of the file that -type does not check.

The default is -P, so the -xtype option will try to determine the resultant file, not the symlink itself. Actually, I get some positive results, which seems like a bug. The -P -xtype l should return true (on a symlink) iff the resultant is itself a symbolic link.

Can also use: ls -FA | sed -ne 's/@//p' which will display only the symlinks.

    `sed -ne 's/@//p'` (and even `sed -ne 's/@$//p'`) is not a secure test, as the first version will give a false positive when `@` occurs anywhere in the *ls* output, and the second will return a false postive when a filename actually ends in `@` – Peter.O Oct 04 '11 at 04:39

To find out only the files that are symlinks inside the current directory:

find . -type l -printf '%p -> %l\n'

This will recursively list all the symlink files. Also, it shows the actual files it points to.
