column

Format standard input or file into multiple columns. Rows are filled before columns; default separator is whitespace.

Format output for a 30 characters wide display:

printf "header1 header2\nbar foo\n" | column -c {{30}}

Specify column delimiter character for the -t option (i.e. "," for csv); default is whitespace:

printf "header1,header2\nbar,foo\n" | column -s{{,}}

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

printf "header1 header2\nbar foo\n" | column -t

Fill columns before filling rows:

printf "header1\nbar\nfoobar\n" | column -c {{30}} -x
