In fact, there's no fundamental difference between the contents of a binary file and the contents of a text file - it's the metadata and file headers that let your computer know which is which. If you were to use a hex editor, it would display any and all files in hexadecimal instead. The reason that your text editor displays the binary file in this manner is that it simply displays all files in this manner. In fact, the symbol is the value zero, meaning the bits at that location would be eight zeroes. This pair, such as are taken together to represent a single byte. Escape codes, as seen here, begin with ^ and are followed by a single additional character. The special cases I mentioned before are so-called control characters that are displayed with an escape code. If you see a string of readable text, such as _stub_helper, it means that particular text is stored as-is within the binary file. Often, one character in your editor corresponds to one byte in the actual file, though there are special cases.

The symbols it picks are determined by your editor's default encoding. When you open the binary file in a text editor, it is showing you these byte-sized chunks instead of each individual bit. A single byte, as you may know, can store any of 256 different values from eight zeroes to eight ones. Nearly all modern computers deal with bytes, instead of the individual bits. To show the contents of file filename in hexadecimal, just run the xxd command without any options with just the filename as argument in Terminal:Ġ0000000: cffa edfe 0700 0001 0300 0080 0200 0000. This works equally for both binary and text files.Ī more compact and commonly used form, which is preferred over binary is hexadecimal, which uses a base 16 number system (0-9, A-F). It will display the binary dump of filename on standard output. One such way is using the built-in xxd command in macOS. To view a file in the most basic form of 0's and 1's, you'll need to use a special editor mode which is capable of displaying the binary data of a file. Everything ultimately boils down to binary when stored in a computer. A binary file is shown in a text editor according to the default encoding set for that editor.Īlso, if an editor is configured to show binary output, it will also display every file, even plain text ones, in terms of 0's and 1's. Showing a binary file in terms of 0 and 1 would make the output unnecessarily lengthy, and is not the most optimal approach. There are layers of abstractions at work as to how files are handled by a computer. When speaking of a file, it refers to a file containing non-textual data (executables, libraries, data files etc.).Ī binary file that can be run as a process is called an executable binary.Ī file being binary file doesn't simply mean that it will be displayed simply in terms of 0's and 1's. In terms of number system, it refers to a base 2 number system which uses two symbols, 0 and 1. When dealing with computers, there are two interpretations of the word binary. When I open it using vi editor: crafts-MBP:bin ldl$ vi see there shows so many and some English signal, such as: _stub_helper.
