What is binary file in linux

What is the difference between binary file and .exe file? [closed]

Is the purpose of this question to clarify binary vs. executable files, or the difference between the .bin and .exe filename extensions?

The question is just fine. They’re talking about colloquial use of the word binary. If the word binary is ambiguous then the answer should be more comprehensive. See accepted answer.

binary file is pretty much everything that is not plain text, that is contains data encoded in any different way than text encoding (ASCII, UTF-8, or any of other text encodings, e.g. ISO-8859-2). A text file may be a plaintext document, like a story or a letter, it can be a config file, or a data file — anyway, if you use a plain text editor to open it, the contents are readable. A binary is any file that is not a text file (nor «special» like fifo, directory, device etc.)

That may be a mp3 music. That may be a jpg image. That may be a compressed archive, or even a word processor document — while for practical purposes it’s text, it is encoded (written on disk) as binary. You need a specific program to open it, to make sense of it — for a text editor the contents are a jumbled mess.

Now, in Linux you’ll often hear «binaries» when referring to «binary executable files» — programs. This is because while sources of most programs (written in high-level languages) are plain text, compiled executables are binary. Since there are quite a few compiled formats (a.out, ELF, bytecode. ) they are commonly called binaries instead of dwelling on what internal structure they have — from user’s point of view they are pretty much the same.

Now, .exe is just another of these compiled formats — one common to MS Windows. It’s just a kind of binaries, compiled and linked against Windows API.

Linux Binary Directories Explained

Binaries are files that contain compiled source code (or machine code). Binary files are the files which contain compiled source code (or machine code). They are also called executable files because they can be executed on the computer.

Binary directory contains following directories:

The /bin directory contains binaries for use by all users. The ‘/bin’ directory also contains executable files, Linux commands that are used in single user mode, and common commands that are used by all the users, like cat, cp, cd, ls, etc. According to the FHS the /bin directory should contain /bin/cat and /bin/date (among others). The ‘/bin’ directory doesn’t contain directories.

Other /bin directories

You can find a /bin subdirectory in many other directories. A user named Amy could put her own programs in /home/amy/bin. Some applications, often when installed directly from source will put themselves in /opt. A samba server installation can use /opt/samba/bin to store its binaries.

The /sbin contains binaries to configure the operating system. The ‘/sbin’ directory also contains executable files, but unlike ‘/bin’ it only contains system binaries which require root privilege to perform certain tasks and are helpful for system maintenance purpose. e.g. fsck, root, init, ifconfig, etc. Many of the system binaries require root privilege to perform certain tasks.

The ‘/lib’ directory contains shared libraries which are often used by the ‘/bin’ and ‘/sbin’ directories. It also contains kernel module. These filenames are identable as ld* or lib*.so.*. For example, ld-linux.so.2 and libfuse.so.2.8.6. Below is an example of the partial contents of /lib.

$ ls /lib/libc*

/lib/libc-2.5.so /lib/libcfont.so.0.0.0 /lib/libcom_err.so.2.1

/lib/libcap.so.1 /lib/libcidn-2.5.so /lib/libconsole.so.0

/lib/libcap.so.1.10 /lib/libcidn.so.1 /lib/libconsole.so.0.0.0

/lib/libcfont.so.0 /lib/libcom_err.so.2 /lib/libcrypt-2.5.so

1) /lib/modules: The ‘/lib/modules’ stores kernel modules and has a directory for each installed kernel. Typically, the Linux kernel loads kernel modules from /lib/modules/$kernel-version/. Modules are meant to use extra hardware support without making a new kernel.

2) /lib32 and /lib64: We currently are in a transition between 32-bit and 64-bit systems. During compilation time of libraries, you’ll encounter through the directories named ‘/lib32’ and ‘/lib64’ which will clarify register size to be used. A 64-bit system may have compatibility for 32-bit binary.

The term ‘opt’ is short for optional. Its main purpose is to store optional application software packages. In many cases this is software from outside the distribution repository. Add-on applications from individual vendors should be installed in ‘/opt’. In some systems ‘/opt’ is empty as they may not have any add-on application. A large package can install all its files in /bin, /lib, /etc subdirectories within /opt/$packagename/. If for example the package is called wp, then it installs in /opt/wp, putting binaries in /opt/wp/bin and man pages in /opt/wp/man.
