Links shell configuration files to a Dropbox folder

Link Shell Files with Dropbox

Keeping shell configuration files in sync with Dropbox so each of my Macs has the same paths, aliases and other settings is easily done by symlinking files to a common folder in Dropbox. If a symlink is already in place it unlinks it so that it can be linked again. Then if the Dropbox exists it creates the symlink. If a file is at that path it won't change anything. You will first need to copy the contents of the folder to the path under the Dropbox path.

#!/bin/sh

set -e

DROPBOX_ROOT="~/Dropbox/Root"
${DROPBOX_ROOT}

link_dropbox_path()
{
    DROPBOX_PATH=$1
    ROOT_PATH=$2

    if [ -L "${ROOT_PATH}" ]; then
        unlink "${ROOT_PATH}"
    fi
    if [ -f "${DROPBOX_PATH}" ] || [ -d "${DROPBOX_PATH}" ]; then
        ln -s "${DROPBOX_PATH}" "${ROOT_PATH}"
        echo "Linked ${ROOT_PATH} to ${DROPBOX_PATH}"
    else
        echo "error: path not found: ${DROPBOX_PATH}"
        exit 1
    fi
}
