dotsync.sh

#!/usr/bin/env bash

# This bash script synchronises dotfiles by exporting each file specified
# in the `dotfiles` array from the `$FROM` directory path to the `$TO`
# directory path.
# If a specified file cannot be found, `cp` will log a path error and
# continue onto the next file.
#
# NOTE
# You can make this script executable by setting the following:
# `chmod +x dotsync.sh`
# 
# COMMANDS
# `import <from> <to>`
# `export <to> <from>`

# unicode checkmark char
CHECKMARK="\u2713"

# the dotfiles to be synced
DOTFILES=(.zshrc .bash_profile .gitconfig .vimrc)

# default <source-directory> & <target-directory> parameters
DEFAULT_FROM="$HOME"
DEFAULT_TO=$(pwd) # present working directory

# CLI parameters
DIRECTION="$1"
FROM="${2:-$DEFAULT_FROM}"
TO="${3:-$DEFAULT_TO}"
