Fmt copies the given files (standard input by default) to its standard output, filling and indenting
lines. The options are
-ln Output line length is n, including indent (default 70).
-wn A synonym for -l.
-in Indent n spaces (default 0).
-j 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:
-a Normally htmlfmt suppresses the contents of form fields and anchors (URLs and image files); this
flag causes it to print them, in square brackets.
-ccharset
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.
-uurl Use url as the base URL for the document when displaying anchors; sets -a.
