COLUMN(1) OpenBSD Reference Manual COLUMN(1)NAMEcolumn - columnate lists
SYNOPSIScolumn [-tx] [-c columns] [-s sep] [file ...]
DESCRIPTION
The column utility formats its input into multiple columns. Rows are
filled before columns. Input is taken from file operands, or, by
default, from the standard input. Empty lines are ignored.
The options are as follows:
-c columns
Output is formatted for a display columns wide.
-s sep Specify a set of characters to be used to delimit columns for the
-t option.
-t Determine the number of columns the input contains and create a
table. Columns are delimited with whitespace, by default, or
with the characters supplied using the -s option. Useful for
pretty-printing displays.
-x Fill columns before filling rows.
ENVIRONMENT
COLUMNS The environment variable COLUMNS is used to determine the size
of the screen if no other information is available.
EXIT STATUS
The column utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
List the current working directory's contents, in detail, with nicely
formatted headings for each of the fields:
$ (echo "PERM LINKS OWNER GROUP SIZE MONTH DAY HH:MM/YEAR NAME" ; \
ls -l | sed 1d) | column-t
