49 utility is a filter which displays the specified files, or standard
50 input if no files are specified, in a user specified format.
52 The options are as follows:
53 .Bl -tag -width ".Fl I , L , l"
55 Specify the input address base.
64 which specify decimal, octal, hexadecimal
65 addresses or no address, respectively.
67 Output named characters.
79 Output C-style escaped characters.
83 Output unsigned decimal ints.
87 Output unsigned decimal shorts.
91 Output double-precision floating point numbers.
95 Output single-precision floating point numbers.
99 Output hexadecimal ints.
103 Output hexadecimal shorts.
107 Output signed decimal longs.
111 Output signed decimal ints.
117 bytes of the combined input before dumping.
118 The number may be followed by one
123 which specify the units of the number as blocks (512 bytes), kilobytes and
124 megabytes, respectively.
134 Output signed decimal shorts.
138 Specify the output format.

158 Non-printing characters are
159 represented as 3-digit octal character codes, except the following
160 characters, which are represented as C escapes:
162 .Bl -tag -width carriage-return -compact
179 Multi-byte characters are displayed in the area corresponding to the first
180 byte of the character.
181 The remaining bytes are shown as
186 .Op Cm C | S | I | L | Ar n
