Blank down selected columns of a CSV file. That is to say, this
command will redact any consecutive identical cells as per column selection.
This can be useful as a presentation trick or a compression scheme.
The "blank" term comes from OpenRefine and does the same thing.
Usage:
xan blank [options] [<input>]
xan blank --help
blank options:
-s, --select <cols> Selection of columns to blank down.
-r, --redact <value> Redact the blanked down values using the provided
replacement string. Will default to an empty string.
Common options:
-h, --help Display this message
-o, --output <file> Write output to <file> instead of stdout.
-n, --no-headers When set, the file will be considered as having no
headers.
-d, --delimiter <arg> The field delimiter for reading CSV data.
Must be a single character.
