Linux Shell Script to Sync Directories Interactively

This script will sync two directories between two servers. Basically we are using rsync features to run this program. Script will interactively request to input below details.

1) Remote server name or ip

2) Remote system user name

3) Local directory to sync

4) Remote directory to sync to

5) Check user need to copy timestamp and preserve permissions

#Tell with shell to use

#!/bin/bash

#Ask user to enter remote server ip or name

while [[ -z ${RS} ]]

do

echo -n "Remote syncing server ip/name: "

#Save input into variable with name RS

read RS

done

#Ask user to enter remote server user

while [[ -z ${RU} ]]

do

echo -n "Remote syncing server user: "

#Save input into variable with name RU

read RU

done

#Ask user if copy timestamp and preserve permissions, valid input is Yes or No, will ask until valid input

while  [[ "$TS" != "Yes" && "$TS" != "No" ]]

do

echo -n "Copying with timestamp and preserve permissions : Yes/No "

#Save input into variable with name TS

read TS

done

#If user need to copy timestamp and preserve permissions we need to use key -p additionally.

if [ "$TS" = "Yes" ]

then

TS=" -p "

else

#If no need to copy timestamp and preserve permissions, we don't need to use any additional key

TS=""

#Ask user to enter local directory to sync, also check if directory exist

while [[ -z ${LD} || !( -d ${LD}) ]]

do

echo -n "Syncing local directory location: "

#Save input into variable with name LD

read LD

done

#Ask user to enter remote directory

while [[ -z ${RD} ]]

do

echo -n "Remote Syncing directory location: "

#Save input into variable with name RD

echo -n "Syncing ..."

#Run sync with presented parameters

rsync -r $TS ${LD} ${RU}@${RS}:${RD} --progress
