This is a CLI File Manager made as a part of RS School NodeJS course.

The file manager can do the following:

• Perform basic file operations (copy, move, delete, rename, etc.)
• Get information about the host machine operating system
• Perform hash calculations (sha256)
• Compress and decompress files, using Brotli Algorithm

How to use:

1. Clone this repo

https://github.com/ITboo/nodejs-file-manager.git

2. Go to task repo

cd nodejs-file-manager

3. Start the program by running:

Copy file:

cp path_to_file path_to_new_directory

Move file:

mv path_to_file path_to_new_directory

Delete file:

rm path_to_file

• Operating system info (prints following information in console)

Get EOL (default system End-Of-Line) and print it to console

os --EOL

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

os --cpus

Get home directory and print it to console

os --homedir

Get current system user name and print it to console

os --username

Get CPU architecture for which Node.js binary has compiled and print it to console

os --architecture

• Hash calculation

Calculate hash for file and print it into console

hash path_to_file

• Compress and decompress operations

Compress file

compress path_to_file path_to_destination

Decompress file

decompress path_to_file path_to_destination

Example:

compress test.txt test

decompress ./test.txt.br test
