vi your_filename
hit esc
Type :%!xxd
to view the hex strings, the n :%!xxd -r
to return to normal editing.
hexdump -C yourfile.bin
unless you want to edit it of course. Most linux distros have hexdump
by default (but obviously not all).
If you want to open binary files (in CentOS 7):
strings <binary_filename>
You can open emacs (in terminal mode, using emacs -nw
for instance), and then use Hexl mode: M-x hexl-mode
.
https://www.gnu.org/software/emacs/manual/html_node/emacs/Editing-Binary-Files.html
to convert a file to its binary codes(hexadecimal representation) we say:
xxd filename #
e.g:
xxd hello.c #
to see all the contents and codes in a binary file , we could use commands like readelf
and objdump
, hexdump
,... .
for example if we want to see all the convert all the contents of a binary file(executable, shared libraries, object files) we say:
hexdump binaryfilename
e.g.
hexdump /bin/bash
but readelf is the best utility for analyzing elf(executable and linking format) files. so if we say:
readelf -a /bin/bash
all the contents in the binary file bash would be shown to us, also we could provide different flags for readelf to see all the sections and headers of an elf file separately, for example if we want to see only the elf header we say:
readelf -h /bin/bash
for reading all the segments of the file:
readelf -l /bin/bash
for reading all the sections of the file:
readelf -S /bin/sh
but again as summary , for reading a normal file like "hello.c" and a binary file like bash in path /bin/bash in linux we say:
xxd hello.c
readelf -a /bin/bash
$ echo -n 'Hello world!' | hd
00000000 48 65 6c 6c 6f 20 77 6f 72 6c 64 21 |Hello world!|
0000000c
You can use hexdump binary file
sudo apt-get install hexdump
hexdump -C yourfile.bin
sudo apt-get install bless
Bless is GUI tool which can view, edit, seach and a lot more. Its very light weight.
As a fallback there's always od -xc filename
