Backup Script

[danielson]

I have this backup script that works well,
#/bin/bash

finished="false"

while [ "$finished" = "false" ]
do
clear

#chose the path to be backedup

echo "Enter the path of the directory to be backed up"

read backup_location

#chose the path of the destination

echo "Enter the path of where you want the backup saved"

read destination_location



#informing us if the backup was successful or not
tar -cvf $destination_location $backup_location
code=$?
if [ $code -eq 0 ]
then
echo "Backup successfull"
else
echo "Backup did not work press any key to run again or n to exit"
fi



#the loop to either exit or restart the program



read resp

if [ "$resp" = "n" ]
then
finished="true"
fi
done

echo "exiting backup.sh"

But i need to modify it so that to run it you just have to type,
./backup.sh <directory to be backed up> <directory to save to>
then the script automaticly does evereythong so i do not have to propmt users once the command ahs been entered but i have no idea how to split the two variables adn take them from after the initial command and use them in the script.

How can i split the variables and get teh script to run with one simple command

thanks for your help i am new to scripting

Hi and Welcome to the LinuxForums !

You can use $#, $*, $1, $2, $3.... etc to access parameters passed with script name.
Here is an example:

#!/bin/bash

# Its a test script : test.sh

echo "First Parameter : \$1 = $1"
echo "Second parameter : \$2 = $2"
echo "Total passed parameters : \$# = $#"
echo " All parameters : \$* = $*"
exit 0

Save it as test.sh and execute this

chmod +x test.sh
./test.sh This is a test script

This is a test script are parameters passed to script test.sh.
Check linuxcommand.org too.

HTH !
