NAME

       expand - convert tabs to spaces

SYNOPSIS

       expand [-t1,t2, ...] [file]

OPTIONS

       -t     Tab stop positions

EXAMPLES

       expand -16,32,48,64 # Expand stdin with tabs every 16 columns

DESCRIPTION

       Expand replaces tabs in the named files with the equivalent numbers of spaces.  If no files are listed, stdin is given.	If only one tab is
       given, the rest are multiples of it.  The default is a tab every 8 spaces.

NAME

     expand, unexpand -- expand tabs to spaces, and vice versa

SYNOPSIS

     expand [-t tab1,tab2,...,tabn] [file ...]
     unexpand [-a] [-t tab1,tab2,...,tabn] [file ...]

DESCRIPTION

     The expand utility processes the named files or the standard input writing the standard output with tabs changed into blanks.  Backspace
     characters are preserved into the output and decrement the column count for tab calculations.  The expand utility is useful for pre-process-
     ing character files (before sorting, looking at specific columns, etc.) that contain tabs.

     The unexpand utility puts tabs back into the data from the standard input or the named files and writes the result on the standard output.

     The following options are available:

     -a      (unexpand only) By default, only leading blanks and tabs are reconverted to maximal strings of tabs.  If the -a option is given, then
	     tabs are inserted whenever they would compress the resultant file by replacing two or more characters.

     -t tab1,tab2,...,tabn
	     Set tab stops at column positions tab1, tab2, ..., tabn.  If only a single number is given, tab stops are set that number of column
	     positions apart instead of the default number of 8.
