Several Unix dialects use the whereis command to find where programs, or executables, are stored in the file structure of the computer.
To use it at the Unix prompt, enter (replace "command" with the executable you're looking for)

whereis command



$ whereis ls
ls: /bin/ls /usr/share/man/man1/ls.1


Not all Linux distros come with "whereis", and there you could try the alternative "which" command instead, for example:

$ which ls


Note: you could resort to using the "find" command, but that command is more intended to walk through directories, looking for files matching certain criteria.
