- 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 `String`:
|
|
|
|
`csvtool {{[-c|--column]}} {{2}} {{[-s|--search]}} '{{^String$}}' {{path/to/file.csv}}`
|
|
|
|
- Extract lines from a CSV file where the second column starts with `Bar`:
|
|
|
|
`csvtool {{[-c|--column]}} {{2}} {{[-s|--search]}} '{{^Bar}}' {{path/to/file.csv}}`
|
|
|
|
- Find lines in a CSV file where the second column ends with `Baz` and then extract the third and sixth columns:
|
|
|
|
`csvtool {{[-c|--column]}} {{2}} {{[-s|--search]}} '{{Baz$}}' {{path/to/file.csv}} | csvtool {{[-e|--no-header]}} {{[-c|--column]}} {{3,6}}`
