digitalmars.D.learn - minor question of the difference between " and '

string pwdxCommand = escapeShellCommand("pwdx", to!string(pid));
writeln("pwdxCommand = ", pwdxCommand);

Output:
     Current process ID: 7962
     pwdxCommand = 'pwdx' '7962'


I'm confused as to why the writeln statement didn't output "pwdx 
7962"?
Afterall, isn't that the definition of a string?  So what's up 
with the two groupings of single quotes?

BTW, those aren't backticks?  (think that is what the key is 
called)

Thanks in advance.

No, they are not backticks. This is: ` :)

 Thanks in advance.


I haven't used it myself but judging from it's documented purpose, those 
quotes are used to allow spaces so that the shell considers it a single 
command line argument as a whole:

grep 'foo bar' *
git commit -m 'My message'
etc.
