how to get the owner and group of a file

[alepage]

Hello, I am using the following code to get the owner and group and it works well only if there is no space into the macro variable provided. 

ex:

%macro find_owner(f);
* this will find the file owner;
filename fog pipe "ls -la &f. | awk '{print $3, $4}'";

data _null_ ;
infile fog truncover delimiter="|";
input xvalue :$256.;
call symput('owner',strip(substr(xvalue,1,index(xvalue," "))));
call symput('group',strip(substr(xvalue,index(xvalue," "),200)));
run;
%put &=owner &=group;
%mend find_owner;

The first call is working properly because there is no blank into the macro variable &f.

%find_owner(/finsys/lego816/saspgm/sasmacro/program1.sas);

But for the second one, there is a blank into the macro variable &f.  between lego and 816.  Is there a way to overcome this situation.

%find_owner(/finsys/lego 816/saspgm/sasmacro/program1.sas);

Also, when there is a space into the path or file name, I am not sure the macro macro variable will pick the complete path and program name.

Forget about the question, I have found the solution which is to put the information provided in the call is single quote.

You can post the answer, corrected, and mark that as the solution. I'm certain someone else will ask this or google it at some point.

For example:

%find_owner('/finsys/lego 816/saspgm/sasmacro/program1.sas');

I think you are overcomplicating things:

data _null_;
infile "ls -l '&f.'" pipe;
input perms :$10. links owner :$8. group :$8.;
call symputx("owner",owner);
call symputx("group",group);
run;

%put &=owner &=group;
