-.Dd April 18, 1994 -.Dt HEXDUMP 1 -.Os -.Sh NAME -.Nm hexdump -.Nd ascii, decimal, hexadecimal, octal dump -.Sh SYNOPSIS -.Nm hexdump -.Op Fl bcdovx -.Op Fl e Ar format_string -.Op Fl f Ar format_file -.Op Fl n Ar length -.Bk -words -.Op Fl s Ar skip -.Ek -.Ar file ... -.Sh DESCRIPTION -The hexdump utility is a filter which displays the specified files, or -the standard input, if no files are specified, in a user specified -format. -.Pp -The options are as follows: -.Bl -tag -width Fl -.It Fl b -.Em One-byte octal display . -Display the input offset in hexadecimal, followed by sixteen -space-separated, three column, zero-filled, bytes of input data, -in octal, per line. -.It Fl c -.Em One-byte character display . -Display the input offset in hexadecimal, followed by sixteen -space-separated, three column, space-filled, characters of input -data per line. -.It Fl d -.Em Two-byte decimal display. -Display the input offset in hexadecimal, followed by eight -space-separated, five column, zero-filled, two-byte units -of input data, in unsigned decimal, per line. -.It Fl e Ar format_string -Specify a format string to be used for displaying data. -.It Fl f Ar format_file -Specify a file that contains one or more newline separated format strings. -Empty lines and lines whose first non-blank character is a hash mark -.Pf ( Cm \&# ) -are ignored. -.It Fl n Ar length -Interpret only -.Ar length -bytes of input. -.It Fl o -.Em Two-byte octal display. -Display the input offset in hexadecimal, followed by eight -space-separated, six column, zero-filled, two byte quantities of -input data, in octal, per line. -.It Fl s Ar offset -Skip -.Ar offset -bytes from the beginning of the input. -By default, -.Ar offset -is interpreted as a decimal number. -With a leading -.Cm 0x -or -.Cm 0X , -.Ar offset -is interpreted as a hexadecimal number, -otherwise, with a leading -.Cm 0 , -.Ar offset -is interpreted as an octal number. -Appending the character -.Cm b , -.Cm k , -or -.Cm m -to -.Ar offset -causes it to be interpreted as a multiple of -.Li 512 , -.Li 1024 , -or -.Li 1048576 , -respectively. -.It Fl v -The -.Fl v -option causes hexdump to display all input data. -Without the -.Fl v -option, any number of groups of output lines, which would be -identical to the immediately preceding group of output lines (except -for the input offsets), are replaced with a line comprised of a -single asterisk. -.It Fl x -.Em Two-byte hexadecimal display. -Display the input offset in hexadecimal, followed by eight, space -separated, four column, zero-filled, two-byte quantities of input -data, in hexadecimal, per line. -.El -.Pp -For each input file, -.Nm hexdump -sequentially copies the input to standard output, transforming the -data according to the format strings specified by the -.Fl e -and -.Fl f -options, in the order that they were specified. -.Ss Formats -A format string contains any number of format units, separated by -whitespace. -A format unit contains up to three items: an iteration count, a byte -count, and a format. -.Pp -The iteration count is an optional positive integer, which defaults to -one. -Each format is applied iteration count times. -.Pp -The byte count is an optional positive integer. -If specified it defines the number of bytes to be interpreted by -each iteration of the format. -.Pp -If an iteration count and/or a byte count is specified, a single slash -must be placed after the iteration count and/or before the byte count -to disambiguate them. -Any whitespace before or after the slash is ignored. -.Pp -The format is required and must be surrounded by double quote -(" ") marks. -It is interpreted as a fprintf-style format string (see -.Xr fprintf 3 ) , -with the -following exceptions: -.Bl -bullet -offset indent -.It -An asterisk (*) may not be used as a field width or precision. -.It -A byte count or field precision -.Em is -required for each ``s'' conversion -character (unlike the -.Xr fprintf 3 -default which prints the entire string if the precision is unspecified). -.It -The conversion characters ``h'', ``l'', ``n'', ``p'' and ``q'' are -not supported. -.It -The single character escape sequences -described in the C standard are supported: -.Bd -ragged -offset indent -compact -.Bl -column <alert_character> -.It NUL \e0 -.It <alert character> \ea -.It <backspace> \eb -.It <form-feed> \ef -.It <newline> \en -.It <carriage return> \er -.It <tab> \et -.It <vertical tab> \ev -.El -.Ed -.El -.Pp -Hexdump also supports the the following additional conversion strings: -.Bl -tag -width Fl -.It Cm \&_a Ns Op Cm dox -Display the input offset, cumulative across input files, of the -next byte to be displayed. -The appended characters -.Cm d , -.Cm o , -and -.Cm x -specify the display base -as decimal, octal or hexadecimal respectively. -.It Cm \&_A Ns Op Cm dox -Identical to the -.Cm \&_a -conversion string except that it is only performed -once, when all of the input data has been processed. -.It Cm \&_c -Output characters in the default character set. -Nonprinting characters are displayed in three character, zero-padded -octal, except for those representable by standard escape notation -(see above), -which are displayed as two character strings. -.It Cm _p -Output characters in the default character set. -Nonprinting characters are displayed as a single -.Dq Cm \&. . -.It Cm _u -Output US ASCII characters, with the exception that control characters are -displayed using the following, lower-case, names. -Characters greater than 0xff, hexadecimal, are displayed as hexadecimal -strings. -.Bl -column \&000_nu \&001_so \&002_st \&003_et \&004_eo -.It \&000\ nul\t001\ soh\t002\ stx\t003\ etx\t004\ eot\t005\ enq -.It \&006\

em\t01A\ sub\t01B\ esc\t01C\ fs\t01D\ gs -.It \&01E\ rs\t01F\ us\t0FF\ del -.El -.El -.Pp -The default and supported byte counts for the conversion characters -are as follows: -.Bl -tag -width "Xc,_Xc,_Xc,_Xc,_Xc,_Xc" -offset indent -.It Li \&%_c , \&%_p , \&%_u , \&%c -One byte counts only. -.It Xo -.Li \&%d , \&%i , \&%o , -.Li \&%u , \&%X , \&%x -.Xc -Four byte default, one, two and four byte counts supported. -.It Xo -.Li \&%E , \&%e , \&%f , -.Li \&%G , \&%g -.Xc -Eight byte default, four byte counts supported. -.El -.Pp -The amount of data interpreted by each format string is the sum of the -data required by each format unit, which is the iteration count times the -byte count, or the iteration count times the number of bytes required by -the format if the byte count is not specified. -.Pp -The input is manipulated in ``blocks'', where a block is defined as the -largest amount of data specified by any format string. -Format strings interpreting less than an input block's worth of data, -whose last format unit both interprets some number of bytes and does -not have a specified iteration count, have the iteration count -incremented until the entire input block has been processed or there -is not enough data remaining in the block to satisfy the format string. -.Pp -If, either as a result of user specification or hexdump modifying -the iteration count as described above, an iteration count is -greater than one, no trailing whitespace characters are output -during the last iteration. -.Pp -It is an error to specify a byte count as well as multiple conversion -characters or strings unless all but one of the conversion characters -or strings is -.Cm \&_a -or -.Cm \&_A . -.Pp -If, as a result of the specification of the -.Fl n -option or end-of-file being reached, input data only partially -satisfies a format string, the input block is zero-padded sufficiently -to display all available data (i.e. any format units overlapping the -end of data will display some number of the zero bytes). -.Pp -Further output by such format strings is replaced by an equivalent -number of spaces. -An equivalent number of spaces is defined as the number of spaces -output by an -.Cm s -conversion character with the same field width -and precision as the original conversion character or conversion -string but with any -.Dq Li \&+ , -.Dq \&\ \& , -.Dq Li \&# -conversion flag characters -removed, and referencing a NULL string. -.Pp -If no format strings are specified, the default display is equivalent -to specifying the -.Fl x -option. -.Pp -.Nm hexdump -exits 0 on success and >0 if an error occurred. -.Sh EXAMPLES -Display the input in perusal format: -.Bd -literal -offset indent -"%06.6_ao " 12/1 "%3_u " -"\et\et" "%_p " -"\en" -.Ed -.Pp -Implement
