copy_file: copy file

In rmflight/waitcopy: Copying files within certain hours and waiting between each one

Description

Copy a single file from one location to another

Usage

copy_file(from_file = NULL, to_dir = ".", json_data = NULL,
  tmp_loc = "/tmp", clean_file_fun = clean_filename)

Arguments

from_file	the location of the original file
to_dir	the location to copy the file to
json_data	the json meta information data
tmp_loc	temp location if you want to specify it
clean_file_fun	function used to rename the file

Details

We want to keep track of information about the copied files, so this function does some stuff to help us out. It strips special characters from the base file name, copies the file to a temp location, calculates the SHA-1 hash of the file, checks the JSON meta file for matches to the SHA-1, and if there are none, copies the renamed file to the copy location.

If a matching instance of SHA-1 hashes are found, then the file path is added to the entry for that file location.

If a matching file name is found but with a different SHA-1 hash, then the first 8 characters of the SHA-1 hash are appended to the file, and it is added to the database.
