I'm running in linux and I'm trying to parse a number of rows formatted as follows (file name and directory structure will be variable)

06/16/17 09:40:19.8344320410 /workspace/alphabuilder/data-jp/D160125.DB

 

The goal from this example is a data set where each record includes

Date = 06/16/17

Time =09:40:19.83 

File = D160125.DB

Folder = /workspace/alphabuilder/data-jp/

 

My Sas code

 

/*Test varaibles*/

%let folder = /workspace/uat/card2/ai/x796785/V_drive/alphabuilder/data-jp/ ;
%let prefix = M ;
%let suffix = db ;

 

Filename dirlist pipe "find &folder. -iname &prefix.*&suffix. -printf '%TD %TT %p\n'";

 

Data &outlist (keep=folder filename date time);                                        
       Infile dirlist end=last;
       format date mmddyy10. time time8.;
       input;
       
       *Create the folder= file directory location;
       date = input(_infile_,mmddyy10.);
  time = input(substr(_infile_,10,18),time8.);
  filename = substr(_infile_,length(_infile_) - index(reverse(_infile_),"/") + 2,length(_infile_));
  folder = substr(_infile_,29,length(_infile_)- index(reverse(_infile_),"/") );
  
 Run;

 

My problem:

Folder includes the filename at the end

/workspace/alphabuilder/data-jp/D160125.DB

 

I tried a number of variations including

folder = substr(_infile_,29,length(_infile_)- 5 );

folder = substr(_infile_,29,35 );

 

I'm sure this is a rookie issue but I haven't been able to google a solution.

Assuming I correctly understand what you're trying to do:

data have;
  fullpath='/workspace/alphabuilder/data-jp/D160125.DB';
  call scan(fullpath, -1, position, length,'/');
  folder=substr(fullpath,1,position-1);
  filename=scan(fullpath,-1,'/');
run;

Like this?

 FOLDER=substr(_infile_,29,find(_infile_,'/',-999)-29);

There's also the FINFO approach.

I think you're overcomplicating things:

data want;
input date :mmddyy8. time :time20. pathstr :$100.;
format
  date mmddyy8.
  time time11.2
  file_name $50.
;
file_name = scan(pathstr,-1,'/');
drop pathstr;
cards;
06/16/17 09:40:19.8344320410 /workspace/alphabuilder/data-jp/D160125.DB
;
run;

It presumes that nobody fucked up by putting blanks into filenames; if that is a possibility, the initial read for pathstr would have to be done with a fixed format from a given position.
