+## dump all MySQL databases at once
+
+```bash
+for i in $(mysqlshow -uroot -p | awk '{print $2}' | grep -v Databases); do mysqldump -uroot -p $i > $i.sql; done
+```

+## mysqldump without the artwork
+
+Often you want to get results from the mysql client without all the ASCII box table formatting and column names.
+
+The `-B` or `--batch` option will force the output to be TAB delimited no matter where the output is going.
+
+The `-N` option will turn off column names in the output.
+
+The following outputs the result of the query in TAB delimited format without column names:
+
+```bash
+mysql -B -N -e "select distinct table_schema from information_schema.tables"
+```
