Bi-Directional Directory Synchronization

Requires rsync:

sudo apt-get install rsync

Custom script sync-directories.sh:

#!/bin/bash
#
# Bi-directional synchronization between folders. Always keep the most recent version of files.
#
#   The synclist is an array of strings, each string is a pipe-delimited pair of directories.
#   Each directory MUST have the "/" at the end of it, otherwise it will create new folders.
#   Spaces are okay as long as the string is quoted.
#   Example: "/dir1/|/dir2/"
#

synclist=(\
  "/home/user/Documents/Personal Documents/Recipes/|/shares/Public/Recipes/" \
  "/home/user/Documents/Workfiles/|/shares/Private/Work/" \
  )

logfile="/logs/sync-directories.log"

IFS=$(echo -en "\n\b")
for pair in ${synclist[@]};do
  dir1=$(echo $pair|awk -F"|" '{print $1}')
  dir2=$(echo $pair|awk -F"|" '{print $2}')
  stat="FAILED"
  if [[ -d "$dir1" ]] && [[ -d "$dir2" ]];then

    rsync -rptuv "$dir1" "$dir2"

    echo -e "\nSYNC : $dir2 <--> $dir1"
    rsync -rptuv "$dir2" "$dir1"
    result2=$?
    if [[ $result1 ]] && [[ $result2 ]];then
      stat="SUCCESS"
    fi
  fi
  echo "[$(date)] $stat : $dir1 <--> $dir2" >>$logfile
