I've created a Cron task at my webhost to daily backup my database and I would like it to append the current date to the filename.
My Cron job looks like this
mysqldump -u username -pPassword db_name > www/db_backup/db_backup+date%d%m%y.sql
But the file I get is this: db_backup+date no file extension or date.
I've also tried this command
mysqldump -u username -pPassword db_name > www/db_backup/db_backup_'date +%d%m%y'.sql
but that doesn't even give an file output.
What is the right syntax for getting the date appended to my file??
* * * * * echo "hello" > /tmp/helloFile_$(date +\%Y\%m\%d\%H\%M\%S).txt
You just need to escape the parentheses.
