Send files to Trash on Mac, imitating shell command rm as closely as possible. Based on https://apple.stackexchange.com/a/162354/105139 and https://gist.github.com/dabrahams/14fedc316441c350b382528ea64bc09c

## rem

import os
import sys

    files = []
    for arg in sys.argv[1:]:
        if os.path.exists(arg):
            p = os.path.abspath(arg).replace('\\', '\\\\').replace('"', '\\"')
            files.append('the POSIX file "' + p + '"')
        else:
            print "rem:", arg + ": No such file or directory"
    if len(files) > 0:
        cmd = ['osascript', '-e',
               'tell app "Finder" to move {' + ', '.join(files) + '} to trash']
        sys.exit(subprocess.call(cmd, stdout=open(os.devnull, 'w')))

    print "       move file(s) to Trash"
