       adjust - simple text formatter

       column] tabsize] [files]...

       The command is a simple text formatter for filling, centering, left and
       right justifying, or only right	justifying  text  paragraphs,  and  is
       designed	 for  interactive  use.	  It  reads the concatenation of input
       files (or standard input if none are given) and	produces  on  standard
       output  a formatted version of its input, with each paragraph formatted
       separately.  If is given as an input filename, reads standard input  at
       that point (use as an argument to separate from options.)

       reads  text  from  input	 lines as a series of words separated by space
       characters, tabs, or newlines.  Text lines are grouped into  paragraphs
       separated  by  blank lines.  By default, text is copied directly to the
       output, subject only to simple filling (see below) with a right	margin
       of 72, and leading spaces are converted to tabs where possible.

       The command recognizes the following command-line options:

	      Do not convert leading space characters to tabs on output;
			(output	 contains  no tabs, even if there were tabs in

	      Center text on each line.
			Lines are pre- and post-processed, but no  filling  is

	      Justify text.
			After filling, insert spaces in each line as needed to
			right justify it (except in  the  last	line  of  each
			paragraph) while keeping the justified left margin.

	      After  filling  text,  adjust the indentation of each line for a
	      smooth right
			margin (ragged left margin).

	      Set the right fill margin to the given column number, instead of
			Text  is  filled,  and	optionally right justified, so
			that no output line extends  beyond  this  column  (if
			possible).   If	 is given, the current right margin of
			the first line of each paragraph is used for that  and
			all subsequent lines in the paragraph.

			By  default,  text is centered on column 40.  With the
			option sets the middle column of the  centering	 "win‐
			dow",  but  auto-sets  the right side as before (which
			then determines the center of the "window").

	      Set the tab size to other than the default (eight columns).

       Only one of the and options is allowed in a single command line.

       Before doing anything else to a	line  of  input	 text,	first  handles
       backspaces,  rubbing  out preceding characters in the usual way.	 Next,
       it ignores all nonprintable characters except tab.  It then expands all
       tabs to spaces.

       For simple text filling, the first word of the first line of each para‐
       graph is indented the same amount as in the input line.	Each  word  is
       then  carried  to  the output followed by one space.  "Words" ending in
       terminal_character[quote][closing_character] are followed by  two  spa‐
       ces,  where  terminal_character	is any of or quote is a single closing
       quote or double-quote character (), and close is any  of	 or  Here  are
       some examples:

       does not place two spaces after a pair of single closing quotes follow‐
       ing a terminal_character).

       starts a new output line whenever adding a word (other than  the	 first
       one) to the current line would exceed the right margin.

       understands  indented first lines of paragraphs (such as this one) when
       filling.	 The  second  and  subsequent  lines  of  each	paragraph  are
       indented	 the  same amount as the second line of the input paragraph if
       there is a second line, else the same as the first line.

       also has a rudimentary understanding of tagged paragraphs
		 (such as this one) when filling.  If the  second  line	 of  a
		 paragraph is indented more than the first, and the first line
		 has a word beginning at the same indentation  as  the	second
		 line,	the  input  column  position  of the tag word or words
		 (prior to the one matching the second	line  indentation)  is

       Tag words are passed through without change of column position, even if
       they extend beyond the right margin.  The rest of the line is filled or
       right justified from the position of the first nontag word.

       When is given, uses an intelligent algorithm to insert spaces in output
       lines where they are most needed, until the lines extend to  the	 right
       margin.	 First, all one space word separators are examined.  One space
       is added to each separator, starting with the one having the most  let‐
       ters  between  it and the preceding and following separators, until the
       modified line reaches the right margin.	If all	one  space  separators
       are increased to two spaces and more spaces must be inserted, the algo‐
       rithm is repeated with two space separators, and so on.

       Output line indentation is held to one less than the right margin.   If
       a single word is larger than the line size (right margin minus indenta‐
       tion), that word appears on a line by itself,  properly	indented,  and
       extends	beyond	the right margin.  However, if is used, such words are
       still right justified, if possible.

       If the current locale defines class names and (see iswctype(3C)),  for‐
       mats  the text in accordance with the character classification and mar‐
       gin settings (see and options).

   Environment Variables
       provides a default value for the	 internationalization  variables  that
       are  unset or null.  If is unset or null, the default value of "C" (see
       lang(5)) is used.  If any of the	 internationalization  variables  con‐
       tains  an  invalid  setting, will behave as if all internationalization
       variables are set to "C".  See environ(5).

       If set to a nonempty string value, overrides  the  values  of  all  the
       other internationalization variables.

       determines the interpretation of text as single and/or multi-byte char‐
       acters, the classification of characters as printable, and the  charac‐
       ters matched by character class expressions in regular expressions.

       determines the locale that should be used to affect the format and con‐
       tents of diagnostic messages written to standard error and  informative
       messages written to standard output.

       determines the location of message catalogs for the processing of

   International Code Set Support
       Single- and multi-byte character code sets are supported.

       complains  to  standard	error and later returns a nonzero value if any
       input file cannot be opened (it skips the file).	 It does the same (but
       quits  immediately)  if	the  argument to or is out of range, or if the
       program is improperly invoked.

       Input lines longer than are silently split (before  tab	expansion)  or
       truncated  (afterwards).	  Lines	 that  are too wide to center begin in
       column 1 (no leading spaces).

       This command is useful for filtering text while in vi(1).  For example,

       reformats the rest of the current  paragraph  (from  the	 current  line
       down), evening the lines.

       The command:

       (where  denotes	control	 characters)  sets up a useful "finger macro".
       Typing (Ctrl-X) reformats the entire current paragraph.

       is a simple way to break text into separate words  without  whitespace,
       except for tagged-paragraph tags.

       This  program is designed to be simple and fast.	 It does not recognize
       backslash to escape whitespace or other characters.  It does not recog‐
       nize  tagged paragraphs where the tag is on a line by itself.  It knows
       that lines end in newline or null,  and	how  to	 deal  with  tabs  and
       backspaces,  but	 it does not do anything special with other characters
       such as form feed (they are simply ignored).  For  complex  operations,
       standard text processors are likely to be more appropriate.

       This  program could be implemented instead as a set of independent pro‐
       grams, fill, center, and justify	 (with	the  option).	However,  this
       would  be  much less efficient in actual use, especially given the pro‐
       gram's special knowledge of tagged paragraphs and last lines  of	 para‐

       was developed by HP.
