What are Binary Files?

Binary files are simply executable code that has already been compiled for a specific system. If you have ever noticed a file on your Windows computer that ends in .exe, this is an example of executable code (or binary file) for a Windows operating system.

To search for a specific binary to see if it is installed, simply use the


command via SSH. To see if PHP6 is installed for instance, you would type

whereis php6

and press ENTER. The output will show you the paths to binary files, library files, etc. if installed.

There are many commonly used binaries available on our shared hosting servers for your use however manual installation of any additional binaries will likely not function as intended. It may be possible to install some applications by compiling them from the source code and installing them in your webspace however this will likely require overriding of some environment variables.
