-.Dt VIS 1
-.Os
-.Sh NAME
-.Nm vis
-.Nd display non-printable characters in a visual format
-.Sh SYNOPSIS
-.Nm
-.Op Fl cbflnostw
-.Op Fl F Ar foldwidth
-.Op Ar
-.Sh DESCRIPTION
-The
-.Nm
-utility is a filter for converting non-printable characters
-into a visual representation.
-It differs from
-.Ql cat -v
-in that
-the form is unique and invertible.
-By default, all non-graphic
-characters except space, tab, and newline are encoded.
-A detailed description of the
-various visual formats is given in
-.Xr vis 3 .
-.Pp
-The options are as follows:
-.Bl -tag -width indent
-.It Fl b
-Turns off prepending of backslash before up-arrow control sequences
-and meta characters, and disables the doubling of backslashes.
-This
-produces output which is neither invertible or precise, but does
-represent a minimum of change to the input.
-It is similar to
-.Dq Li cat -v .
-.It Fl c
-Request a format which displays a small subset of the
-non-printable characters using C-style backslash sequences.
-.It Fl F
-Causes
-.Nm
-to fold output lines to
-.Ar foldwidth
-columns (default 80), like
-.Xr fold 1 ,
-except
-that a hidden newline sequence is used (which is removed
-when inverting the file back to its original form with
-.Xr unvis 1 ) .
-If the last character in the encoded file does not end in a newline,
-a hidden newline sequence is appended to the output.
-This makes
-the output usable with various editors and other utilities which
-typically do not work with partial lines.
-.It Fl f
-Same as
-.Fl F .
-.It Fl l
-Mark newlines with the visible sequence
-.Ql \e$ ,
-followed by the newline.
-.It Fl n
-Turns off any encoding, except for the fact that backslashes are
-still doubled and hidden newline sequences inserted if
-.Fl f
-or
-.Fl F
-is selected.
-When combined with the
-.Fl f
-flag,
-.Nm
-becomes like
-an invertible version of the
-.Xr fold 1
-utility.
-That is, the output
-can be unfolded by running the output through
-.Xr unvis 1 .
-.It Fl o
-Request a format which displays non-printable characters as
-an octal number, \eddd.
-.It Fl s
-Only characters considered unsafe to send to a terminal are encoded.
-This flag allows backspace, bell, and carriage return in addition
-to the default space, tab and newline.
-.It Fl t
-Tabs are also encoded.
-.It Fl w
-White space (space-tab-newline) is also encoded.
-.El
-.Sh SEE ALSO
-.Xr unvis 1 ,
-.Xr vis 3
-.Sh HISTORY
-The
-.Nm
-command appeared in
-.Bx 4.4 .
-.Sh BUGS
-Due to limitations in the underlying
-.Xr vis 3
-function, the
-.Nm
-utility
-does not recognize multibyte characters, and thus may consider them to be
-non-printable when they are in fact printable (and vice versa).
