# column

> Format standard input or a file into multiple columns.
> Columns are filled before rows; the default separator is a whitespace.
> More information: <https://man.archlinux.org/man/core/util-linux/column.1>.

- Format the output of a command for a 30 characters wide display:

`printf "header1 header2\nbar foo\n" | column --output-width {{30}}`

- Split columns automatically and auto-align them in a tabular format:

`printf "header1 header2\nbar foo\n" | column --table`

- Specify the column delimiter character for the `--table` option (e.g. "," for csv) (defauls to whitespace):

`printf "header1,header2\nbar,foo\n" | column --table --separator {{,}}`

- Fill rows before filling columns:

`printf "header1\nbar\nfoobar\n" | column --output-width {{30}} --fillrows`
