In a cronjob copy files and change their names to unique values

rated 0 times [ 2] [ 0] / answers: 1 / hits: 3741 / 2 Years ago, wed, july 6, 2022, 6:33:46

I want to make a cronjob that makes a copy of every file in /var/log, and puts it in /etc/bak. That i do by making an sh file saying

cp /var/log/*.* /etc/bak

I would like these files not to be overwritten, but to be unique. To do this i figured i want to put the date/time in the filename. Is there any way to make that possible on a batch file copy?

How about putting every batch of log files in a separate directory. You could do it using:

dir=/etc/bak/`date "+%Y-%m-%d_%H.%M.%S"`

mkdir "$dir"

cp /var/log/*.* $dir

If you want to prefix all the copied files with a timestamp you can do:

(cd /var/log && ls -1 *.*) | awk -v date=`date "+%Y-%m-%d_%H.%M.%S"` '{ print "cp /var/log/" $0 " /etc/bak/" date  $0}' | sh
