Node.js File Manager

The program is started by npm-script start in following way:

npm run start -- --username=your_username

List of operations and their syntax:

• Navigation & working directory (nwd)

  • Go upper from current directory (when you are in the root folder this operation shouldn't change working directory)

  up

  • Go to dedicated folder from current directory (path_to_directory can be relative or absolute)

  cd path_to_directory

  • List all files and folder in current directory and print it to console

  ls

• Basic operations with files

  • Read file and print it's content in console:

  cat path_to_file

  • Create empty file in current working directory:

  add new_file_name

  • Rename file:

  rn path_to_file new_filename

  Example: rn user/file.txt newFile.txt
  

  • Copy file:

  cp path_to_file path_to_new_directory

  Example: cp user/file.txt documents/
  

  • Move file (same as copy but initial file is deleted):

  mv path_to_file path_to_new_directory

  Example: mv user/file.txt documents/
  

  • Delete file:

  rm path_to_file

• Operating system info (prints following information in console)

  • Get EOL (default system End-Of-Line)

  os --EOL

  • Get host machine CPUs info (overall amount of CPUS plus model and clock rate (in GHz) for each of them)

  os --cpus

  • Get home directory:

  os --homedir

  • Get current system user name (Do not confuse with the username that is set when the application starts)

  os --username

  • Get CPU architecture for which Node.js binary has compiled

  os --architecture

• Hash calculation

  • Calculate hash for file and print it into console

  hash path_to_file

• Compress and decompress operations

  • Compress file (using Brotli algorytm)

  compress path_to_file path_to_destination

  Examples:

  compress file.txt /
  result: created file.txt.br in the same directory as source
  

  compress file.txt newFile.br
  result: created newFile.br in the same directory as source
  

  • Decompress file (using Brotli algorytm)

  decompress path_to_file path_to_destination

  Examples:

  decompress file.txt.br /
  result: created file.txt in the same directory as source
  

  decompress file.txt.br newFile.txt
  result: created newFile.txt in the same directory as source
  

  decompress file.txt documents/
  result: created documents/file.txt
