[Solved] How to tar data along with current system date and time.?
Hi all,

Following is my small script:-
Code:
#!/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
Code:
system1-DR.11Jan2013-08:12:31.tar

Could you please guide me on this.
I am getting interest in scripting now, I am beginner, I need your advice.

Thanks in advance,
Manali

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:
Code:
#!/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


Code:
#!/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.

Please advise.
Thanks,

however the tar file got removed by the script.

---------- Post updated at 02:09 AM ---------- Previous update was at 02:07 AM ----------

Code:
scp *.tar backupserver:/DRFiles/system1

tar file showing Date but not Time

The colon : in the time-stamp is causing issue. Create time-stamp without colon :
Code:
TS=$( date +"%d%b%Y-%H-%M-%S" )

---------- Post updated at 02:22 AM ---------- Previous update was at 02:17 AM ----------

wow sir it worked!
but one question
system1-DR.31Jan2013-21-49-05.tar is the file created
and time on local system is:
Code:
Thursday, January 31, 2013  9:49:29 PM CET

and on target system is
Code:
Thu Jan 31 23:27:42 CET 2013

---------- Post updated at 02:22 AM ---------- Previous update was at 02:22 AM ----------

---------- Post updated at 02:24 AM ---------- Previous update was at 02:22 AM ----------
