Question Find file using date appended to file name
The script below is a backup script I wrote.
It Tars and gzips files and move them to backup folder.
It appends the current date of action to the name of the .tar.gz file

echo “Taking Domain Backup...”
hostname
echo “Tarring internetprod”
sleep 2
cd /usr/web/bea/projects/domains
tar -cvf internetprod_`date “+%d%b%Y”`.tar internetprod
echo “Zipping internetprod”
sleep 2
gzip internetprod_`date “+%d%b%Y”`.tar
echo “Moving internetprod_date.tar.gz to Backup folder”
sleep 2
mv internetprod_`date “+%d%b%Y”`.tar.gz /usr/weblogic/Backup

what I want to do now is to reverse the process in case there is a disaster.
i want to be able to loop through the files in the backup filder and identfy the most current file by the appended date, move it to /usr/web/bea/projects/domains gunzip and untar it to over write the current internetprod file.

The other option i am considering is to have interractive script, that will request for the date in “+%d%b%Y” format compare it to the dates appended to the file name and gunzip and untar the file to over write internetprod file in the /usr/web/bea/projects/domains folder
can you help?

try:

Code:
file=`ls -trl /usr/weblogic/Backup | tail -1 | awk '{ print $NF}' `
mv  $file /usr/web/bea/projects/domains/ &&  gzip $file && tar -xvf ${file%%.gz}

ls -trl /usr/weblogic/Backup | tail -1 will sort the files on mtime and pick the most recent one

| awk '{ print $NF}' ` will give the filename on a long list

mv $file /usr/web/bea/projects/domains/ moving the file.tar.gz

&& gzip $file && tar -xvf ${file%%.gz} if the above one is successful, unzip the tar ball and if that is successful, extract the tar

thanx,
the files currently in the backup folder saved in this format
internetprod_08Jul2009.tar.gz
internetprod_09Jul2009.tar.gz
internetprod_10Jul2009.tar.gz
internetprod_11Jul2009.tar.gz
internetprod_12Jul2009.tar.gz
and what I want to do is select the most current using the most current date appended to internetprod_. in this case the most current is internetprod_12Jul2009.tar.gz
looks like your script is using mtime the file was last modified.
I want to avoid this because, if anyone should temper with any of the files, the script may consider it as most current.
