fmt, htmlfmt – simple text formatters


fmt [ option ... ] [ file ... ]

htmlfmt [ -a ] [ -c charset ] [ -u url ] [ file ... ]


Fmt copies the given files (standard input by default) to its standard output, filling and indenting lines. The options are

-l n

Output line length is n, including indent (default 70).  

-w n

A synonym for -l.  

-i n

Indent n spaces (default 0).  


Do not join short lines: only fold long lines.  

Empty lines and initial white space in input lines are preserved. Empty lines are inserted between input files.

Fmt is idempotent: it leaves already formatted text unchanged.

Htmlfmt performs a similar service, but accepts as input text formatted with HTML tags. It accepts fmt’s -l and -w flags and also:


Normally htmlfmt suppresses the contents of form fields and anchors (URLs and image files); this flag causes it to print them, in square brackets.  

-c charset

change the default character set from iso-8859-1 to charset. This is the character set assumed if there isn’t one specified by the html itself in a <meta> directive.  

-u url

Use url as the base URL for the document when displaying anchors; sets -a.  





Htmlfmt makes no attempt to render the two-dimensional geometry of tables; it just treats the table entries as plain, to-be-formatted text.
