I have a directory structure where there are multiple symlinks at random depths.

For illustration purpose:

/fs
/fs/afile
/fs/blink -> /usr/local/lib
/fs/cdir/cfile
/fs/cdir/cdir/cdir/clink -> /var/log
/fs/edir/edir/efile
/fs/edir/elink -> /usr/local/bin

I want to find which file or folder utilizes the most space to do some cleanup. I am hoping an output similar to:

3.0G     /fs
4.0G     /fs/afile
3.3G     /fs/cdir
15.0G    /fs/edir

I tried running cd /fs && find -maxdepth 1 -type d | sudo xargs du -hs but this expands the symlinks underneath, which means the size of /fs/edir would include the content and size of /usr/local/bin in this case.

TLDR: For a given path, how do I find the size of all files or directories at depth=1, without expanding any underneath symlinks?

Note: I read du skip symbolic links but this case is different as the symlink in this case could be of any depth.

    Is your du an alias? The standard mandates du not to follow symlinks by default, anywhere in the file hierarchy. And neither does the GNU du I'm testing with. – fra-san Mar 22 at 8:57
  • Interesting, I thought symlinks were expanded because the size I get from du is larger than the df total disk space. Maybe I am missing something else here... – Victor Wong Mar 22 at 9:56

    Then you should look for mount points. If some other device is mounted under /fs, then du will include it in its results unless you use its -x (skip directories on different file systems) option. – fra-san Mar 22 at 10:46
