Question

I want to maintain multiple dated backups via cron but I can’t seem to figure out how to concatenate the file name in cron.

Currently I just use the following:

/bin/mv /var/www/vhosts/mysite.org/dbBackups/today.sql /var/www/vhosts/mysite.org/dbBackups/yesterday.sql

/usr/bin/mysqldump --add-drop-table -u dbname -pmypass dbname > /var/www/vhosts/mysite.org/dbBackups/today.sql

What I tried was no good:

/usr/bin/mysqldump/mysqldump --add-drop-table -u dbname -pmypass dbname > '/var/www/vhosts/mysite.org/dbBackups/' . date +%Y%m%d . dbname.sql

So how do I concantenate that string in cron?

Answer 1

/usr/bin/mysqldump/mysqldump --add-drop-table -u dbname -pmypass dbname > "/var/www/vhosts/mysite.org/dbBackups/"`date +%Y%m%d`dbname.sql
