# reorder and reformat a file in columns
|
|
#
|
|
# this utility takes lines from its standard input and reproduces them,
|
|
# partially reordered and reformatted, on its standard output.
|
|
#
|
|
# It has the same effect as a 'sort | column -t', with the exception
|
|
# that empty lines, as well as lines which start with a '#' sign, are
|
|
# not affected, i.e. they keep their position and formatting, and act
|
|
# as separators, i.e. the parts before and after them are each sorted
|
|
# separately (but overall field widths are computed across the whole
|
|
# input).
|
|
#
|
|
# Options:
|
|
# -i:
|
|
# --ignore-case:
|
|
# Do not consider case when sorting.
|
|
# -d:
|
|
# --default:
|
|
# What to chage empty fields to.
|
|
# -s <N>:
|
|
# --split=<N>:
|
|
# Treat only the first N whitespace sequences as separators.
|
|
# line content after the Nth separator will count as only one
|
|
# field even if it contains whitespace.
|
|
# Example : '-s 2' causes input 'a b c d e' to be split into
|
|
# three fields, 'a', 'b', and 'c d e'.
|
|
#
|
|
# boards.cfg requires -ids 6.
