su doesn't change the user of your shell, it runs a
new shell, reading from standard input. If you want it to run any particular text you'll have to feed that text into it, it won't automatically read lines from some other shell.
If this is your own hobby machine, you can install
sudo and enable it for everyone in the
wheel group with the NOPASSWD option. Using
expect when you don't have to is
like this.

FMT(1) General Commands Manual FMT(1)
NAME
fmt, htmlfmt - simple text formatters
SYNOPSIS
fmt [ option ... ] [ file ... ]
htmlfmt [ -a ] [ -c charset ] [ -u url ] [ file ... ]
DESCRIPTION
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).
-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.
-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.
SOURCE
/src/cmd/fmt.c
/src/cmd/htmlfmt
BUGS
Htmlfmt makes no attempt to render the two-dimensional geometry of tables; it just treats the table entries as plain, to-be-formatted text.
