RedHat [Solved] Simple script not working- for loop
Hi all,
Please guide me writing this script
Follwing is the file which I have created, which contains the files to be copied.
Code:
cat system1-dr.txt
/etc/passwd
/etc/shadow
/etc/group
/etc/vfstab
/etc/profile
/etc/default/init
/etc/shells
/etc/dfs/dfstab
/etc/dfs/sharetab
/etc/default/password

This is the small script I have written for this task , but when I execute it instead of files defined in system1-dr.txt getting copied system1-dr.txt file get copied.
below is the script
Code:
cat script1
for i in /users/jack/system1-dr.txt
do
sudo cp $i /users/jack/DRbep01
done
cd  /users/jack/DRbep01
tar-cvf system1.tar *
scp system1.tar backupserver:/users/jack/stsyem1

Could you please guide me in this and how more sophiscated script can I make it..?

Use while loop instead...

Code:
 
while read i
do
sudo cp $i /users/jack/DRbep01
done</users/jack/system1-dr.txt

Your script should be like this..

Code:
 
$cat script1
 
while read i
do
sudo cp $i /users/jack/DRbep01
done</users/jack/system1-dr.txt
cd  /users/jack/DRbep01
tar-cvf system1.tar *
scp system1.tar backupserver:/users/jack/stsyem1

replace
Code:
for i in /users/jack/system1-dr.txt

with
Code:
for i in `cat /users/jack/system1-dr.txt`

the code between ` ` will be executed and become arguments for "for loop"

Though the previous post is absolutely correct, we here at unix.com are more in favor of pamu's solution for it avoids the use of a not necessary cat command

HI pamu,

Thanks, your while loop works.
But could you all please tell two things

How to put command in this while loop or script which will
-rename /etc/default/passwd to passwd-default as there are two file named passwd on system and other is under /etc/passwd

-secondly this /etc/shadow file is having r-- --- --- permission so first I need to change its permission to say 755 and then copy to /users/jack/DRbep01

It will be great help to me to know this, I am beginner in scripting,I will get idea by your suggestions.

Please advise
Thanks,
Manali
