Hi all,
Following is my small script:-
#!/bin/ksh
for i in `cat /users/jack/mainfile-dr.txt`
do
sudo cp -r $i /users/jack/DR01/.
done
cd /users/jack/DR01/
sudo tar cvf system1-DR.tar *
scp system1-DR.tar backupserver:/DRFiles/system1
sudo rm -rf system1-DR.tar
In this script I copy some imp files to one local folder then tar it and send it via scp to backupserver .
my question is how tar these content along with the current time and date of system when it gets compressed(tared).
something like
system1-DR.11Jan2013-08:12:31.tar
Could you please guide me on this.
Thanks in advance,
Yoda

That is Dangerous Backticks
Use a while loop instead to read the file, here is the modified code to create tar file with time-stamp:
#!/bin/ksh
while read i
do
sudo cp -r "$i" /users/jack/DR01/.
done < /users/jack/mainfile-dr.txt
cd /users/jack/DR01/
TS=$( date +"%d%b%Y-%H:%M:%S" )
sudo tar cvf system1-DR.${TS}.tar *
scp system1-DR.${TS}.tar backupserver:/DRFiles/system1
sudo rm -rf system1-DR.${TS}.tar
Thanks bipinajith for reply...
So you mean to say below script will also work ? with two addtional line above, I hope it will
#!/bin/ksh
cd /users/jack/DR01/
sudo cp /etc/default/passwd /users/jack/passwd-default
while read i
do
sudo cp -r "$i" /users/jack/DR01/.
done < /users/jack/mainfile-dr.txt
cd /users/jack/DR01/
TS=$( date +"%d%b%Y-%H:%M:%S" )
sudo tar cvf system1-DR.${TS}.tar *
scp system1-DR.${TS}.tar backupserver:/DRFiles/system1
sudo rm -rf system1-DR.${TS}.tar
Why you say "That is Dangerous Backticks", can you explain in single line, I saw that link but no idea..
Thanks again,
I will check your date code in my script now.

There is a kernel limitation ARG_MAX . If the data fetched inside the back-ticks is not within this limit, your script will fail.
So it is always a good programming practice to avoid using such construct.
Hey bipinath,
ssh: system1-DR.31Jan2013-21: node name or service name not known
Please advise.

scp *.tar backupserver:/DRFiles/system1

The colon : in the time-stamp is causing issue. Create time-stamp without colon :
TS=$( date +"%d%b%Y-%H-%M-%S" )
wait I need to ask something more

Local system time.
Because you captured the time-stamp and created your tar file in your local system.
Yes Sir,

Which path are you referring to here? If you are talking about the recursive copy that you are performing, then yes the files will be overwritten.
Wonderful explanation. You solved all my problems.
