| -u | --user | User name (default: SYS) |
| -p | --password | User password (default: MANAGER) |
| -P | --port | Server port number (default: 5656) |

| -o | --output | Filename to save query results |
| -i | --silent | Runs without the copyright notice |
| -v | --verbose | Detailed output |
| -r | --format | Specifies output file format (default: csv) |
| -h | --help | Displays options |
| -c | N/A | Add Connection parameter(Supported from version 6.1 or later) |
Example:
machsql -s localhost -u sys -p manager machsql --server=localhost --user=sys --password=manager machsql -s localhost -u sys -p manager -f script.sql # Supported from version 6.1 or later machsql -s 127.0.0.1 -u sys -p manager -P 8888 -c ALTERNATIVE_SERVERS=192.168.0.147:9209;CONNECTION_TIMEOUT=10
Environment Variable MACHBASE_CONNECTION_STRING
Specifies basic connection parameters. For example, to add CONNECTION_TIMEOUT, ALTERNATIVE_SERVERS, you may use environment variable setting below.
export MACHBASE_CONNECTION_STRING=ALTERNATIVE_SERVERS=192.168.0.148:8888;CONNECTION_TIMEOUT=3
Setting connection parameter with -c option, it takes precedence over environment variables. This option is supported from version 6.1 or later
