Backup script for Linux or OS X

A simple backup script for backing up my laptop. I have an OS X and Linux laptop so I wanted one script to put on both of them:


#!/usr/bin/env

homedir="$(echo $HOME)"
dom=$(date +%d)
###################
# START CONFIGURATION
###################

# On the 15th of the month run an rsync --delete to clean out old file. Otherwise just run a regular rsync.
if [ ${dom} -eq 15 ]; then
  rsynccmnd="rsync --delete -avhz --stats --progress"
else
  rsynccmnd="rsync -avhz --stats --progress"fi

# Path to the exclude file
host=$(uname -a|cut -d ' ' -f 1)
if [ "${host}" = "Darwin" ]; then
 # OS X
 excludefile="path to exclude file for OS X"
 #EXAMPLE
 # excludefile="${homedir}/Documents/Backup/backuplaptop_exclude_osx.txt"
else
 # Linux
 #excludefile="path to exclude file for Linux"

 #EXAMPLE
 # excludefile="${homedir}/Documents/Backup/backuplaptop_exclude_linux.txt"
