Automate creation of large number of directories and files in a file system

FS-Loader

FS-Loader is a program implemented in Python 3 for recursively creating a large number of directories and files.

Below are the command line parameters for the script:

• --mount-directory
  • Required
  • This is the root directory path under which you want to create sub-directories and files
• --sub-directory-depth
  • Optional, default=5
  • This is the sub-directory depth to be created
• --sub-directory-count
  • Optional, default=10
  • This is the count of sub-directories to create under each directory
• --file-count-per-directory
  • Optional, default=10
  • This is the count of files to be created under each sub-directory
• --directory-prefix
  • Optional, default='dir'
  • This is the directory name prefix
• --block-size
  • Optioal, default=4096
  • This is the number of bytes to write in one write operation
• --min-block-count
  • Optional, default=1
  • This is the minimum number of blocks to write to a file
  • With default block size of 4096 bytes and minimum block count of 1, 4kB data will be written to the file
• --max-block-count
  • Optioal, default=256
  • This is the maximum number of blocks to write to a file
  • With default block size of 4096 bytes and maximum block count of 256, 1MB data will be written to the file

Features

• The script displays progress percentage

Sample Cmmand

./fs_loader_main.py --mount-directory '/mnt/test/' --sub-directory-depth 3 --file-count-per-directory 5

Sample Directory Structure Created By The Script
