NAME
expand, unexpand - expand TAB characters to SPACE characters, and vice
versa
SYNOPSIS
expand [-i | --initial] [--help] [-t | --tabs tablist] [file]...
expand [-i | --initial] [--help] [-tabstop]
[-tab1, tab2,. . ., tabn] [file]...
DESCRIPTION
The expand utility copies files (or the standard input) to the standard
output, with TAB characters expanded to SPACE characters. BACKSPACE
characters are preserved into the output and decrement the column count
for TAB calculations. expand is useful for pre-processing character
files (before sorting, looking at specific columns, and so forth) that
contain TAB characters.
unexpand copies files (or the standard input) to the standard output,
putting TAB characters back into the data. By default, only leading
SPACE and TAB characters are converted to strings of tabs, but this can
be overridden by the -a option (see the OPTIONS section below).
OPTIONS
The following options are supported for expand:
-t, --tabs tablist Specifies the tab stops. The argument tablist
must consist of a single positive decimal
integer or multiple positive decimal inte‐
gers, separated by blank characters or com‐
mas, in ascending order. If a single number
is given, tabs will be set tablist column
positions apart instead of the default 8. If
multiple numbers are given, the tabs will be
set at those specific column positions.
Each tab-stop position N must be an integer
value greater than zero, and the list must be
in strictly ascending order. This is taken to
mean that, from the start of a line of out‐
put, tabbing to position N causes the next
character output to be in the (N+1)th column
position on that line.
In the event of expand having to process a
tab character at a position beyond the last
of those specified in a multiple tab-stop
list, the tab character is replaced by a sin‐
gle space character in the output.
-i, --initial Do not convert any TABs after non-SPACE char‐
acters are encountered.
-tabstop Specifies as a single argument, sets TAB
characters tabstop SPACE characters apart
instead of the default 8.
-tab1,tab2,...,tabn Sets TAB characters at the columns specified
by -tab1,tab2,...,tabn
--help Print command usage and exit.
The following options are supported for unexpand:
-a, --all Inserts TAB characters when replacing a run of
two or more SPACE characters would produce a
smaller output file.
--first-only Converts only leading sequences of SPACEs. This
option overrides -a.
-t, --tabs tablist Specifies the tab stops. The option-argument tab‐
list must be a single argument consisting of a
single positive decimal integer or multiple posi‐
tive decimal integers, separated by blank charac‐
ters or commas, in ascending order. If a single
number is given, tabs will be set tablist column
positions apart instead of the default 8. If mul‐
tiple numbers are given, the tabs will be set at
those specific column positions. Each tab-stop
position N must be an integer value greater than
zero, and the list must be in strictly ascending
order. This is taken to mean that, from the start
of a line of output, tabbing to position N will
cause the next character output to be in the
(N+1)th column position on that line. When the -t
option is not specified, the default is the
equivalent of specifying -t 8 (except for the
interaction with -a, described below).
No space-to-tab character conversions occur for
characters at positions beyond the last of those
specified in a multiple tab-stop list.
When -t is specified, the presence or absence of
the -a option is ignored; conversion will not be
limited to the processing of leading blank char‐
acters.
