+# Node Mysql parse
+
+A command line utility for parsing a mysql connection string and generating the correct connection parameters to feed to a mysql command.
+
+## Installation
+
+Install by running `npm install -g mysql-parse`
+
+## Example usage
+
+##Basic
+
+Running `mysql-parse --uri mysql://examplename:somepassword@examplehost:3306/dbname)` will generate string like this `-u examplename -psomepassword -h examplehost -P 3306 dbname` which you can pass to mysql or mysqldump commands.
+
+## Using mysql
+
+`mysql $(mysql-parse --uri <some mysql connection string>)`
+
+## Using mysqldump
+
+`mysqldump $(mysql-parse --uri <some mysql connection string>) > dump.sql`
+
+## Passing in other options to mysql/mysqldump
+
+Because the last thing out of mysql-parse is the database name (if defined in the connection string), options need to be added before mysql-parse like so:
+
+`mysqldump --compact $(mysql-parse --uri <some mysql connection string>) > dump.sql`
+
+## Development
+
+1.  Download this project.
+2.  Run tests with `npm test`.
+3.  Develop and submit PR. Please note: If you are considering substantial changes, please open an issue first because the feature you're thinking of might not be right for this project.
+
