Utility to filter and extract data from CSV formatted sources. More information: https://github.com/maroofi/csvtool.

• Extract the second column from a CSV file:

csvtool {{[-c|--column]}} {{2}} {{path/to/file.csv}}

• Extract the second and fourth columns from a CSV file:

csvtool {{[-c|--column]}} {{2,4}} {{path/to/file.csv}}

• Extract lines from a CSV file where the second column exactly matches Foo:

csvtool {{[-c|--column]}} {{2}} {{[-s|--search]}} '{{^Foo$}}' {{path/to/file.csv}}

• Extract lines from a CSV file where the second column starts with Bar:

csvtool {{[-c|--column]}} {{2}} {{[-s|--search]}} '{{^Bar}}' {{path/to/file.csv}}

• Find lines in a CSV file where the second column ends with Baz and then extract the third and sixth columns:

csvtool {{[-c|--column]}} {{2}} {{[-s|--search]}} '{{Baz$}}' {{path/to/file.csv}} | csvtool {{[-e|--no-header]}} {{[-c|--column]}} {{3,6}}
