cat my.sandbox.cnf | awk -F "=" 'NF < 2 {print} sub("=", "=~placeholder~=") {print}' | awk -F "=~placeholder~=" 'NF < 2 {gsub("-", "_", $0); print} NF==2 {gsub("-", "_", $1); print $1 "=" $2}'

Functions: awk cat

Multi-word parameters in my.cnf can be written with either hyphens or underscores. innodb_file_per_table is the same as innodb-file-per-table, as well as innodb_file-per_table. The script normalizes the parameter names to using underscores only, keeping from changing values (e.g. ?mysql-bin? parameter value should not change).

cat my.cnf | sed '/^#/d' | sed '/^$/d' | sed -e 's/[ \t]\+//g'
mysqldump | sed -n "/^USE \`employees\`/,/^USE \`/p" | sed -n "/^-- Table structure for table \`departments\`/,/^-- Table structure for table/p"

The 'USE' statement only appears in mysqldump's output if multiple databases are exported, or --databases is specified.

This command filters only those statements relating to a specific database ('employees' in the example).

User: ShlomiNoach
Functions: sed

Textually convert the storage engine of MyISAM tables to InnoDB. This solution requires dumping of the database, transforming, and importing onto another server.
