Bash script to make a tree directories

Question

I have a script here, this script will list all directories in current working directory and create sub directories to make a directory tree but the problem is it can't create a directory.

Can anyone help me this out ? The script must create a directory in a specific directory and sub-directories

LIST=`ls -D`
for i in $LIST;
do
mkdir -p $i"/Dir3/Dir4/"
done

Answer 1

Don't parse the output of ls.

Here is one way to "correctly" iterate over directories:

for dir in */; do
    #       ^-- the trailing slash makes $dir expand to directories only
    [ -d "${dir}" ] || continue
    mkdir -p "${dir}/Dir3/Dir4/"
done

Answer 2

LIST=`find . -maxdepth 1 -mindepth 1 -type d`
for i in $LIST;
do
    mkdir -p $i/Dir3/Dir4
done

Answer 3

Do you ask something like this?

find * -type d -exec mkdir -p /var/abc/{} \;

It will take the directory and sub-directories from current folder, and create new same folders under /var/abc
