$cd //Move to your home directory.
$cd MyTestFiles2 //Moves into a directory called MyTestFiles2
$grep "S" MyTestFiles2/*: The grep utility searches all the lines which contain "S" in the specified files or directory MyTestFiles2, if that directory exists. But its returning No such file or directory in your case. This is because, probably you don't have a directory or file with that specified name MyTestFiles2 in the current directory. Please note that, you are already in the directory MyTestFiles2, and it is still further searching for another file/directory inside that directory with the name MyTestFiles2. If you want to do the search in the current directory, you can simply modify the command to $grep "S" .//* which will search for the pattern S in the current directory, or you can move out of this directory, by executing the command $cd, which will move you back to the home directory, and then you can execute the same old command.
