NAME
expand, unexpand - expand tabs to spaces, and vice versa
SYNOPSIS
tablist] [file ...]
tablist] [file ...]
Obsolescent:
tabstop] tabn] [file ...]
DESCRIPTION
processes the named files or the standard input and writes to the standard output with tabs changed into spaces. Backspace characters are
preserved in the output, and the column count is decreased by one column for tab calculations. For proper tab calculation, if a multi-col-
umn character is to be "backspace'd", it should be followed by multiple backspace characters which equal to it's column width. If a tab
character is found after the last tab position, it is replaced by a single space. is useful for preprocessing character files that contain
tabs (before sorting, looking at specific columns, etc).
recognizes the following command-line options and arguments:
tablist specifies where to set the tab positions instead of the default tablist can take two forms. If it is a single num-
ber, tabs are set tablist spaces apart. tablist can also be a blank- or comma-separated list of increasing positions
where tabs are to be set.
This option is obsolescent and is equivalent to using

processes the named files or the standard input and writes to the standard output with spaces changed into tabs where possible. By
default, only leading spaces and tabs are converted to maximal strings of tabs. The default tab position is every 8 characters. Backspace
characters are preserved into the output, and the column count is decreased by one column for tab calculations. For proper tab calcula-
tion, if a multi-column character is to be "backspace'd", it should be followed by multiple backspace characters which equal to it's column
width.
recognizes the following command-line options and arguments:
Tabs are inserted whenever they would compress the resultant file
by replacing two or more spaces before a tab position.
tablist specifies the tab positions. tablist can take two forms. If it is a single number, tabs are set every tablist spa-
ces apart. If tablist is a blank- or comma-separated list of increasing positions, tabs are set at those locations.
The option implies the option. If the option is not specified, the default is equivalent to specifying except that
is not implied for this case.
