expand

expand tabs to spaces 

Command


SYNOPSIS

expand [-t tablist] [file ...]

expand [-number] [-number,number...] [file ...]


DESCRIPTION

expand reads text input from the files specified on the command line, converts tabs into spaces, and writes the result to the standard output. If you do not specify any files on the command line, expand reads from the standard input.

expand preserves backspace characters. By default, tab stops are set every eight columns. A tab after the last tabstop is replaced by a space.

Options

The first syntax of expand accepts the following option:

-t tablist 

sets tab stops at positions indicated by tablist. Numbers in tablist must be in ascending order (origin 0) and separated by commas or blanks; however the list must be one argument so you need shell quoting if you are using blanks. The list may consist of a single number, in which case tabs are set every tablist positions apart.

The second syntax of expand (which the POSIX standard considers obsolete) accepts the following options:

-number 

sets tab stops every number columns.

-number,number... 

sets tab stops at each column number (origin 0).


DIAGNOSTICS

Possible exit status values are:

0 

Successful completion.

1 

Failure due to any of the following:

— cannot open the input file
— insufficient memory
— invalid tab stop specification
