sas, zip large data sets, save space on unix server

[user112a2]

What are the best ways to zip SAS data sets? Below is the code that I have tried using SAS and Putty. In SAS, I did not get a log saying this was successful or not. I did get an ! exclamation point. In Putty, I also did not get any message if successful or not. What are the best and fastest ways to zip large data sets in SAS or Putty? Also, is there a way to do multiple data sets at once? Also, I think a log would be nice as well. Thank you!

this is one way I do some zipping

%macro zipit;
ods package(zip) open nopf;
		proc sql;
			create table sasds as
			select *
			from dictionary.tables
			where libname = 'WORK';
		quit;
		option nonotes;
		%do %while (&sysnobs > 0);
			data sasds;
				set sasds;
				if _N_ = 1 then call symputx('FN',memname);
				else output;
			run;
			%put Archive %sysfunc(PATHNAME(mysas))\&fn..sas7bdat;
			ods package(zip) add file="%sysfunc(PATHNAME(WORK))\&fn..sas7bdat";
		%end;
		option notes;
		ods package(zip) 
		publish archive
		properties (archive_name = "WORK.zip"
				archive_path = "\\&mypath.");
		ods package(zip) close;
%mend zipit;
%zipit;

Are you already using the SAS Compress option?

[VDD]

yes I do compress prior to zipping.  the zipping files I do pack lots of datasets into one file for archiving.

gzip accepts a list of filenames on the commandline.

To see output of external commands in the SAS log, do this:

filename oscmd pipe "gzip filenames 2>&1";

data _null_;
infile oscmd;
input;
put _infile_;
run;

If you count the input lines, you can check for success; gzip will return no output if it succeeded completely.
