Backups all MySQL databases to individual files. Can be put into a script that grabs current date so you have per day backups.

mysql -e 'show databases' | sed -n '2,$p' | xargs -I DB 'mysqldump DB > DB.sql'

No need to loop when we have `xargs`. The sed command filters out the first line of `show databases` output, which is always "Database".

mysql -e 'show databases' -s --skip-column-names | egrep -v "^(test|mysql|performance_schema|information_schema)$" | parallel --gnu "mysqldump --routines {} > {}_daily.sql"

Backs up all databases, excluding test, mysql, performance_schema, information_schema.

Requires parallel to work, install parallel on Ubuntu by running: sudo aptitude install parallel

while read; do mysqldump $REPLY | gzip > "/backup/mysql/$REPLY.sql.gz"; done < <( mysql -e 'show databases' -s --skip-column-names )

Know a better way?

What others think

Typo: for I in $(mysql -e 'show databases' -s --skip-column-names); do mysqldump $I | gzip > $I.sql.gz"; done

quote marks not opened. should read:

for I in $(mysql -e 'show databases' -s --skip-column-names); do mysqldump $I | gzip > "$I.sql.gz"; done

Just out of curiosity, why skip-column-names?
