Compress and | or delete files by mask older than N days

Script performs tasks from configuration file. It works in two modes:

• bundle default mode
  processes files all together
  result = one zip file {yyyyMMdd_HHmmss}_{filescountinbundle}{marker}.zip

• single for compressing large size files
  processes each file separately
  result = one zip per each source file {yyyyMMdd_HHmmss}_{sourcefilename}{marker}.zip)

Running

# it takes start parameters from default config path .\config.txt
.\pacman.ps1

# or specify config file
.\pacman -config_path .\configs\config.json

Config rules

• Config file contains array of dictionaries
• Each element of the array is a task
• Script processes tasks in same order as in config
• Params arc, del, single may not be specified in config, default values used: arc=true, del=true, single=false
• Params path, filter, days are mandatory
• The filter parameter is used for both compression and deletion
• Filter allowes * and ? wildcards
• If days=0, script processes all files with dt < {tomorrow date 00:00:00}
• If days=1, script processes all files with dt < {today date 00:00:00}
• If a critical error occured while checking parameters or performing task, the script stops and exit
