SYNOPSIShex [ options... ] [ file ]
hex -r [ file ]
hex will show the contents of file (or standard input) in hexadecimal and/or character. At this time, this will show in Japanese text as if it seems to be.
OPTIONSYou can specify option in environment variable HEX_OPTIONS
OPTIONS - how to show `non printable character'see EXAMPLE below
`Non printable character' here is that control codes and/or codes that is 8bits and out of range of kanji or kana character codes.
- -c, --color (default if output is tty)
show `non printable character' with colors. Terminal with color support,
MS-DOS Prompt in Windows95
and so on) show all of J with color by
Blue and light bule is used by default, using escape sequence such as ^[[34m These colors can be changed by -cs1, -cs2 option described below.
- -b, --bold
show `non printable character' in bold.
will show all J in bold. It will be showen in bold even if you see via
When output is tty, escape sequence ^[[1m is used, and otherwise (such pipe), it will output like A^HA for bold A.
This program does not refer termcap/terminfo , so some terminal can not show in bold. In Windows95, it looks brighter.
- -d, --dot (default if output is not tty)
- show `non printable character' as `.' as if `J' substituted in `.' in EXAMPLE case.
- -t, --text
- show `non printable character' in normal text. Same as EXAMPLE No use.
- -u, --underline
show `non printable character' with underline.
case, all J has underline. You can see with underline even if you see via
When output to tty, escape sequence ^[[4m is used, otherwise (such as pipe), it will output like _^HA for A with underline. You can't see underline in Windows95.
0x00000000: a4 cf a4 e8 a4 f3 0a 0a - 0a 0a 0a 0a 0a 0a 0a 0a HAYONNJJJJJJJJJJ(actually, "HAYONN" shows in Hiragana characters).
OPTION - output codeTo check what is specified by default, hex -h
- -e, -oe, --oeuc
- output using *euc-japan*
- -s, -os, --osjis
- output using *sjis*
- -j, -oj, --ojis
- output using *iso-2022-jp*
OPTION - input codeTo check what is specified by default, hex -h
- -E, -ie, --ieuc
- Assume *euc-japan* or *iso-2022-jp* for input.
- -S, -is, --isjis
- Assume *sjis* or *iso-2022-jp* for input
- -U, -iu, --iunknown
- Assume unknown input code. Japanese handling won't be done by this option.
OPTION - other
- -cs1 cs, --colorstring1 cs
specify code 1 of color. This color is used for control codes and/or
codes that is 8bits and out of range of kanji or kana character codes.
For example, if you specified -cs1 43;31 (`;' will be handled by shell, so you should escape it as -cs1 '43;31' ), output red character with yellow background.
- -cs2 cs, --colorstring2 cs
- specify code 2 for color. This color is used for half of kanji character, part of EUC halfwidth kana and/or escape sequence of iso-2022.
- -dsiso, --disablesiso, +siso
- Usually, character between ^N/^O is treated as halfwidth kana, but disabled with this option.
- -siso, --enablesiso
- Oppose to above (default)
- -r, --restore
% hex < hoe |
hex -r > hoge
is same as
% cat < hoe > hoge
- -h, --help
- show usage.
PAGERIf you use pager such as less for output of hex, you can't see color however, you can see color by doing like the followings:
% hex -c `which hex` | less -r
% hex -c `which hex` | lv -C
If you use command prompt on WindowsNT, try
% hex -u `which hex` | less
less will show with colors for underline, so it looks like with color option. (disabled hex color option)

This program doesn't refer termcap/terminfo so some terminal can't show bold.
No autodetection of Japanese encodings.
Wrong efficiency for output. (color sequence with each characters. For *iso-2022-jp* output, ^[(J for each characters.)
Space of halfwidth kana ( 0x8e 0xa0 in *euc-japan* , 0xa0 in *sjis* , 0x20 in *iso-2022-jp* ) will output as normal space character ( 0x20 )
You can't see color in some part on Windows95. (bug of Windows95 ?)
No support supplimental characters in *iso-2022-jp*.
