csvgrep

csvgrep is a command-line tool used for searching and filtering CSV files based on specific criteria. It allows users to query CSV files using regular expressions or simple string matching on specific columns.

Some key features of csvgrep are:

1. Searching: csvgrep enables you to search for specific patterns or values within CSV files. You can search for exact matches, partial matches, or pattern matches using regular expressions.

2. Filtering: It allows you to filter rows based on specific conditions. You can filter rows that match specific values in certain columns or rows that meet certain criteria like greater than, less than, or equal to a specific value in a particular column.

3. Column selection: csvgrep also supports column selection, which means you can choose to display only specific columns of the CSV file in the output. This is helpful when you are interested in only certain information rather than the entire dataset.

4. Flexible output: The tool provides various output options, including printing the filtered results to the console or saving them to a new CSV file. This gives you flexibility in how you want to use the filtered data.

Overall, csvgrep is a powerful command-line tool that simplifies the process of searching and filtering data within CSV files, making it a useful tool for data analysis, data cleansing, and data manipulation tasks.
