Is there any tool or script available that creates millions of files directories, sub-directories and sub-sub-directories randomly in Linux and Windows.
CodePudding user response：
mkdir -p folder{1..100000}/folder{1..100000}folder{1..100000}

Thank you Kamèl , Dominique, for your the clue
I could able to achieve what I wanted.
Following example creates and copies files in 4 x 4 x 4 x 4 x 4 = 1024 directories
On Linux Host:
# ls -l
total 440
-rw-r--r--. 1 root root 86400 Nov 4 07:48 file1
-rw-r--r--. 1 root root 86400 Nov 4 07:48 file2
-rw-r--r--. 1 root root 86400 Nov 4 07:48 file3
-rw-r--r--. 1 root root 86400 Nov 4 07:48 file4
-rw-r--r--. 1 root root 86400 Nov 4 07:49 file5
