On windows machine there are lots of third party editors available to edit a binary file. I belive there should be some thing similer buildin in the *nix systems as well. any idea how can i edit a binary file on unix?
You can also try ghex2 GNOME utilities. This give you the automated hex-to-ASCII on the side, as well as the various character/integer decodes at the bottom.

In vim You can type :%!xxd to turn it into a hexeditor. :%!xxd -r to go back to normal mode. xxd is shipped in a vim installation.
See here for some remarks about editing binary files with vim (boils down to :set binary to avoid trouble, use only the "R" or "r" command to change text, don't delete characters).
If You are an Emacs fan, see here for a guide on how to edit a binary file with Emacs.
There are much more hexeditors on Linux/Unix....
I use hexedit on Ubuntu
sudo apt-get install hexedit
Bless is a high quality, full featured hex editor.
It is written in mono/Gtk# and its primary platform is GNU/Linux. However it should be able to run without problems on every platform that mono and Gtk# run. Main Features Bless currently provides the following features:
- Efficient editing of large data files and block devices.
- Multilevel undo - redo operations.
- Customizable data views.
- Fast data rendering on screen.
- Multiple tabs.
- Fast find and replace operations.
- A data conversion table.
- Advanced copy/paste capabilities.
- Highlighting of selection pattern matches in the file.
- Plugin based architecture.
- Export of data to text and html (others with plugins).
- Bitwise operations on data.
- A comprehensive user manual.
I used to use bvi.
I am developing hexvi to overcome :%!xxd and bvi's limitations.
hexvi
Features
- vim-like keybindings and commands
- going to specific offsets
- inserting, replacing, deleting
- searching for stuff (PCRE regexes)
- everything is a command, and can be mapped in
hexvirc - color schemes
- support for large files
- support for multiple files (via tabs)
- Python so the entry level to hack around should be lower than C's
- CLI through and through
Cons
- as of March 2016, it's alpha so features are missing, but I'm working on those:
- file saving
- undo/redo
- command history
- visual selection
- man page
- no autocomplete
bvi
Features
- vim-like keybindings and commands
- going to specific offsets
- inserting, deleting, replacing
- searching for stuff (text and hex)
- undo/redo
- CLI through and through
Cons
- regarding its vim capabilities - unfortunately, it understands only the most
basic things and definitely needs more love in this regard (example: doesn't
understand
:wq, but understands:wand:q) - no visual selection support whatsoever
- no tab/split screen support
- crashes often
- no support for large files
- no command history
- no autocomplete
I like KHexEdit, which is part of KDE
Its "Windows style" UI is probably quite quick to learn for most people (compared to Vim or Emacs anyway :)
There's lightweight binary editor, check hexedit. http://www.linux.org/apps/AppId_6968.html. I tried using it for editing ELF binaries in Linux at least.
I made wxHexEditor, it's open sourced, written with C++/wxWidgets GUI libs and can open even your exabyte sized disk!
Just try.
As variant, you can use radare2:
> r2 -w /usr/bin/ls

I've had good experience with wxHexEditor... just make sure if you are hex-editing a drive you do it via the menu
Devices -> Open Disk Device -> SCSI Disk Drive Partition #_N_
