The Utils

toobigdatadoc (too)

Manage parallel directory structures for separating text files from large binary files and datasets. Creates symlinked folders under HOME/{toobig|toodata|toodoc}:

• toobig - Large files excluded from backups
• toodata - Small-ish data files
• toodoc - Binary files like PDFs and images

$HOME
    |-- toobig
        |-- # replicated folder paths with large files here, assume not to be backed up
    |-- toodata
        |-- # small-ish data files in support of the parallel root
    |-- toodoc
        |-- # usually pdfs or image files

Usage:

too --help

usage: too [-h] {big,data,doc}

Create symlinked parallel folders under HOME/{toobig|toodata|toodoc}, to
contain data/binary files outside of git repo or away from source/text files.

positional arguments:
  {big,data,doc}  large files to exclude from backup, smallish datasets,
                  binary files like pdf

options:
  -h, --help      show this help message and exit
