shake_files

The program rename files. It adds a random prefix. It's can be used for shake files in old mp3 players which doesn't support random functions.

Build:

go build shake_files.go 
go build shake_files2.go

• shake_files - just rename files with random prefix.
• shake_files2 - better version. Firstly it shakes list files and then added sequins number in a file name.

Help:

./shake_files2 -h
Usage of ./shake_files2:
  -d	Rename dirs too
  -p string
    	path to directory with files (default ".")
  -r	Delete prefix in filenames if it exist
  -w	Rename files (Default: Just print result without rename files)
