I like the --group-directories-first flag for ls. My .zshrc has this line in it:

alias ls="ls -h --color='auto' --group-directories-first"

The only thing I don't like is that symbolic links to directories don't get grouped with the directories.

Are there any switches I can add to the ls command that will cause symbolic-links-to-directories to group with directories? I'm disinclined to build a compound command, because I like being able to add additional switches to ls on the fly.

One option is to use the -L flag:

-L, --dereference

when showing file information for a symbolic link, show information for the file the link references rather than for the link itself

For example, assume I have the files and directories below:

$ ls -l --group-directories-first

total 0

drwxr-xr-x. 2 user group 6 Nov 30 08:19 zdir1

drwxr-xr-x. 2 user group 6 Nov 30 08:19 zdir2

-rw-r--r--. 1 user group 0 Nov 30 08:20 file1

-rw-r--r--. 1 user group 0 Nov 30 08:20 file2

lrwxrwxrwx. 1 user group 5 Nov 30 08:23 symlink -> zdir2

The symlink gets sorted with the directories when -L is used:

$ ls -lL --group-directories-first

total 0

drwxr-xr-x. 2 user group 6 Nov 30 08:19 symlink

drwxr-xr-x. 2 user group 6 Nov 30 08:19 zdir1

drwxr-xr-x. 2 user group 6 Nov 30 08:19 zdir2

-rw-r--r--. 1 user group 0 Nov 30 08:20 file1

-rw-r--r--. 1 user group 0 Nov 30 08:20 file2

As you noticed, ls no longer indicates whether the files are symlinks are not. I'm not familiar with a way in ls to show a symlink once it's been dereferenced, but I wrote a hacky bash function to do it for you:

lsd() {

        ls -lL --group-directories-first | while read line; do

                file=$(echo "$line" | awk '{print $NF}')

                ls -ld "$file" 2>/dev/null | grep -q "^l"

                if [ $? -eq 0 ]; then

                        symlink=$(ls -l $file | awk '{print $(NF-2),$(NF-1),$NF}')

                        echo "$line" | sed -e "s/^./l/" -e "s/$file/$symlink/"

                else

                        echo "$line"

                fi

        done

}

Essentially, the script will determine if the file output from ls -lL --group-directories-first is a symlink or not. If it is, the first character is changed to an l, and what the symlink points to is appended to the end of the line.
