unexpand
expand(1) User Commands expand(1)NAME
expand, unexpand - expand TAB characters to SPACE characters, and vice versa
SYNOPSIS
expand [-t tablist] [file...]
expand [-tabstop] [ -tab1, tab2,. . ., tabn] [file...]
unexpand [-a] [-t tablist] [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 tablist Specifies the tab stops. The argument tablist must consist of a single positive decimal integer or multiple posi-
tive decimal integers, separated by blank characters 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 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 output, tabbing to position N causes the next char-
acter 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 mul-
tiple tab-stop list, the tab character is replaced by a single space character in the output.
-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
The following options are supported for unexpand:
-a Inserts TAB characters when replacing a run of two or more SPACE characters would produce a smaller output file.
-t tablist Specifies the tab stops. The option-argument tablist must be a single argument consisting of a single positive decimal
integer or multiple positive decimal integers, separated by blank characters 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 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 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 characters.
OPERANDS
The following ooperand is supported for expand and unexpand:
file The path name of a text file to be used as input.
ENVIRONMENT VARIABLES
See environ(5) for descriptions of the following environment variables that affect the execution of expand and unexpand: LANG, LC_ALL,
LC_CTYPE, LC_MESSAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:
0 Successful completion
>0 An error occurred.
