mysqlimport => used to import data from text files to tables

MySQL utility mysqlimport used import data from any source to a MySQL or Aurora or MariaDB database instance.

mysqlimport [OPTIONS] database file1...fileN
Usage: mysqlimport [OPTIONS] database textfile...

mysqlimport --help

mysqlimport --version

mysqlimport -u root -h localhost -pabc123 testdb dump_file.txt

mysqlimport --local -u root -h localhost -pabc123 testdb export_dump_file.sql

mysqlimport --local --delete -u root -h localhost -p proddb mysql_dump_file.rtf

mysqlimport --login-path=dba --verbose --replace proddb user.sql

mysqlimport --local --compress --user=username --password --host=hostname --fields-terminated-by=',' auroradb sales.product_*

Loads tables from text files in various formats. The base name of the text file must be the name of the table that should be used.
If one uses sockets to connect to the MySQL server, the server will open and read the text file directly. In other cases the client will open the text file. The SQL command 'LOAD DATA INFILE' is used to import the rows.

Default options of mysql import, are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf
The following groups are read: mysqlimport client

  --fields-optionally-enclosed-by=name Fields in the input file are optionally enclosed by the given character.
  --fields-escaped-by=name Fields in the input file are escaped by the given character.

  -f, --force          Continue even if we get an SQL error.
  --get-server-public-key  Request RSA public key from server.
  -?, --help          Displays this help and exits.
  -h, --host=name     Connect to host.
  -i, --ignore        If duplicate unique key was found, keep old row.
  --ignore-lines=#    Ignore first n lines of data infile.
  --lines-terminated-by=name  Lines in the input file are terminated by the given string.
  -L, --local          Read all files through the client.
  -l, --lock-tables    Lock all tables for write (this disables threads).

  --plugin-dir=name    Directory for client-side plugins.
  -P, --port=#               Port number to use for connection or 0 for default to, in order of preference, my.cnf, $MYSQL_TCP_PORT, /etc/services, built-in default (3306).

  -r, --replace      If duplicate unique key was found, replace old row.
  --secure-auth        Refuse client connecting to server if it uses old (pre-4.1.1) protocol. Deprecated. Always TRUE
  --server-public-key-path Path name to file containing RSA public key
  -s, --silent        Be more silent.
  -S, --socket=name    The socket file to use for connection.
