Explanation:
This is a bash script that checks if the previous command executed successfully. If it did not, it moves the file to an error directory and logs an error message along with the table name that failed to load. It also inserts this information into a monitoring table in a MySQL database.
If the previous command executed successfully, it moves the file to a backup directory and continues to the next iteration of the loop.
The variables used in the script are:
$?
- the exit status of the previous command${Csvfile}
- the directory where the CSV files are stored${file}
- the name of the CSV file being loaded${time2}
- the current date and time in the formatYYYY-mm-dd_HH-MM-SS
${tablename}
- the name of the table being loaded${start_time}
- the start time of the script execution${errorinfo_path}
- the path to the log file containing error informationmysql
- the command-line client for MySQL-h
- the host name or IP address of the MySQL server-P
- the port number of the MySQL server-u
- the username to use when connecting to the MySQL server-p
- the password to use when connecting to the MySQL servertest
- the name of the MySQL database to useload_error_info
- the name of the monitoring table in the database
Overall, this script helps to automate the process of loading data from CSV files into a MySQL database while also providing error handling and monitoring capabilities.
