+.Sh NAME
+.Nm cat
+.Nd concatenate and print files
+.Sh SYNOPSIS
+.Nm cat
+.Op Fl benstuv
+.Op Fl
+.Op Ar
+.Sh DESCRIPTION
+The
+.Nm cat
+utility reads files sequentially, writing them to the standard output.
+The
+.Ar file
+operands are processed in command line order.
+A single dash represents the standard input.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl b
+Implies the
+.Fl n
+option but doesn't number blank lines.
+.It Fl e
+Implies the
+.Fl v
+option, and displays a dollar sign
+.Pq Ql \&$
+at the end of each line
+as well.
+.It Fl n
+Number the
+.Ar output
+lines, starting at 1.
+.It Fl s
+Squeeze multiple adjacent empty lines, causing the output to be
+single spaced.
+.It Fl t
+Implies the
+.Fl v
+option, and displays tab characters as
+.Pq Ql ^I
+as well.
+.It Fl u
+The
+.Fl u
+option guarantees that the output is unbuffered.
+.It Fl v
+Displays non-printing characters so they are visible.
+Control characters print as
+.Ql ^X
+for control-X; the delete
+character (octal 0177) prints as
+.Ql ^?
+Non-ascii characters (with the high bit set) are printed as
+.Ql M-
+(for meta) followed by the character for the low 7 bits.
+.El
+.Pp
+The
+.Nm cat
+utility exits 0 on success, and >0 if an error occurs.
+.Sh BUGS
+Because of the shell language mechanism used to perform output
+redirection, the command
+.Dq Li cat file1 file 2 > file1
+will cause the original data in file1 to be destroyed!
