How to view files in binary from bash?

问题:

I would like to view the contents of a file in the current directory, but in binary from the command line. How can I achieve this?

回答1:

xxd does both binary and hexadecimal

bin:

xxd -b file

hex:

xxd file

回答2:

hexdump -C yourfile.bin

unless you want to edit it of course. Most linux distros have hexdump by default (but obviously not all).

回答3:

vi your_filename

hit esc

Type :%!xxd to view the hex strings, the n :%!xxd -r to return to normal editing.

回答4:

As a fallback there's always od -xc filename

回答5:

sudo apt-get install bless

Bless is GUI tool which can view, edit, seach and a lot more. Its very light weight.

You can use hexdump binary file

hexdump -C yourfile.bin

You can open emacs (in terminal mode, using emacs -nw for instance), and then use Hexl mode: M-x hexl-mode.
