mysqldumpsplitter - MySQL Dump splitter to split / extract databases, tables, list from mysqldump with plenty of more funtionality.
Download the utility from website or git repository.
************ Usage ************
sh mysqldumpsplitter.sh --source filename --desc --extract [DB|TABLE|DBTABLES|ALLDBS|ALLTABLES|REGEXP] --match_str string --compression [gzip|pigz|bzip2|none] --decompression [gzip|pigz|bzip2|none] --output_dir [path to output dir] [--config /path/to/config]
--source: mysqldump filename to process. It could be a compressed or regular file.
--desc: This option will list out all databases and tables.
--extract: Specify what to extract. Possible values DB, TABLE, ALLDBS, ALLTABLES, REGEXP
--match_str: Specify match string for extract command option.
--compression: gzip/pigz/bzip2/none (default: gzip). Extracted file will be of this compression.
--decompression: gzip/pigz/bzip2/none (default: gzip). This will be used against input file.
--output_dir: path to output dir. (default: ./out/)
--config: path to config file. You may use --config option to specify the config file that includes following variables.

Ver. 5.0
- Extract single database from mysqldump:
sh mysqldumpsplitter.sh --source filename --extract DB --match_str database-name
Above command will create sql for specified database from specified "filename" sql file and store it in compressed format to database-name.sql.gz.
- Extract single table from mysqldump:
sh mysqldumpsplitter.sh --source filename --extract TABLE --match_str table-name
Above command will create sql for specified table from specified "filename" mysqldump file and store it in compressed format to database-name.sql.gz.
- Extract tables matching regular expression from mysqldump:
sh mysqldumpsplitter.sh --source filename --extract REGEXP --match_str regular-expression
Above command will create sqls for tables matching specified regular expression from specified "filename" mysqldump file and store it in compressed format to individual table-name.sql.gz.
- Extract all databases from mysqldump:
sh mysqldumpsplitter.sh --source filename --extract ALLDBS
Above command will extract all databases from specified "filename" mysqldump file and store it in compressed format to individual database-name.sql.gz.
- Extract all table from mysqldump:
sh mysqldumpsplitter.sh --source filename --extract ALLTABLES
Above command will extract all tables from specified "filename" mysqldump file and store it in compressed format to individual table-name.sql.gz.
- Extract list of tables from mysqldump:
sh mysqldumpsplitter.sh --source filename --extract REGEXP --match_str '(table1|table2|table3)'
Above command will extract tables from the specified "filename" mysqldump file and store them in compressed format to individual table-name.sql.gz.
- Extract a database from compressed mysqldump:
sh mysqldumpsplitter.sh --source filename.sql.gz --extract DB --match_str 'dbname' --decompression gzip
Above command will decompress filename.sql.gz using gzip, extract database named "dbname" from "filename.sql.gz" & store it as out/dbname.sql.gz
- Extract a database from compressed mysqldump in an uncompressed format:
sh mysqldumpsplitter.sh --source filename.sql.gz --extract DB --match_str 'dbname' --decompression gzip --compression none
Above command will decompress filename.sql.gz using gzip and extract database named "dbname" from "filename.sql.gz" & store it as plain sql out/dbname.sql
- Extract alltables from mysqldump in different folder:
sh mysqldumpsplitter.sh --source filename --extract ALLTABLES --output_dir /path/to/extracts/
Above command will extract all tables from specified "filename" mysqldump file and extracts tables in compressed format to individual files, table-name.sql.gz stored under /path/to/extracts/. The script will create the folder /path/to/extracts/ if not exists.
- Extract one or more tables from one database in a full-dump:
Consider you have a full dump with multiple databases and you want to extract few tables from one database.
Extract single database:
`sh mysqldumpsplitter.sh --source filename --extract DB --match_str DBNAME --compression none`
Extract all tables
`sh mysqldumpsplitter.sh --source out/DBNAME.sql --extract REGEXP --match_str "(tbl1|tbl2)"`
though we can use another option to do this in single command as follows:
sh mysqldumpsplitter.sh --source filename --extract DBTABLE --match_str "DBNAME.(tbl1|tbl2)" --compression none
Above command will extract both tbl1 and tbl2 from DBNAME database in sql format under folder "out" in current directory.
You can extract single table as follows:
sh mysqldumpsplitter.sh --source filename --extract DBTABLE --match_str "DBNAME.(tbl1)" --compression none
- Extract all tables from specific database:
mysqldumpsplitter.sh --source filename --extract DBTABLE --match_str "DBNAME.*" --compression none
Above command will extract all tables from DBNAME database in sql format and store it under "out" directory.
- List content of the mysqldump file
mysqldumpsplitter.sh --source filename --desc
Above command will list databases and tables from the dump file.
