- NAME
- unexpand - convert spaces to tabs
-
- SYNOPSIS
- unexpand [-tab1[,tab2[,...]]] [-t tab1[,tab2[,...]]] [-a]
- [+tabs=tab1[,tab2[,...]]] [+all] [file...]
-
- DESCRIPTION
- This manual page documents the GNU version of unexpand.
- unexpand writes the contents of each given file, or the
- standard input if none are given or when a file named `-' is
- given, to the standard output, with strings of two or more
- space or tab characters converted to as many tabs as possi-
- ble followed by as many spaces as are needed. By default,
- unexpand converts only initial spaces and tabs (those that
- precede all non space or tab characters) on each line. It
- preserves backspace characters in the output; they decrement
- the column count for tab calculations. By default, tabs are
- set at every 8th column.

- OPTIONS
-
- -, -_✓t, +_✓t_✓a_✓b_✓s _✓t_✓a_✓b_✓1[,_✓t_✓a_✓b_✓2[,...]]
- If only one tab stop is given, set the tabs _✓t_✓a_✓b_✓1 spaces
- apart instead of the default 8. Otherwise, set the
- tabs at columns _✓t_✓a_✓b_✓1, _✓t_✓a_✓b_✓2, etc. (numbered from 0) and
- leave spaces and tabs beyond the tabstops given
- unchanged. If the tabstops are specified with the -_✓t
- or +_✓t_✓a_✓b_✓s option, they can be separated by blanks as
- well as by commas. This option implies the -_✓a option.
-
- -_✓a, +_✓a_✓l_✓l
- Convert all strings of two or more spaces or tabs, not
- just initial ones, to tabs.
