Interpreting your question as strictly as possible, and assuming you are writing a script wherein you would like to perform this test, the bash built-in "test" command is what you need. You can use square brackets to invoke this command for more standard-looking conditional syntax as follows:

if [ -e /path/to/file ]; then
   whatever;
fi

That's equivalent, syntactically, with:

if test -e /path/to/file; then
  whatever;
fi

Just FYI.

But for questions which are this simple, you should be able to consult the bash manual page (man bash from within bash) and find your own answers.

You could try whereis 'name of file or keyword of file title's. It shows you where the files are that have a certain word in their name.

Checking the man page for whereis, it only works for commands.
