How to reduce the information in a log file - Unix server

[alepage]

Hello,

I don't remember but there is a Unix command or a SAS command to reduce the quantity of information into a log file

See the example below

Not sure what I see in your log, a bigger sample might help to understand.

And what parts do you want to remove?

Try this to see what option are available, and what they are set to:

proc options group=logcontrol;
run;

too many libref information

usually One line for libref cntpdmu will be sufficient, no libref work

[SASKiwi · Accepted solution]

Those "LIBREF=" messages are not generated by SAS. SAS ones usually start with NOTE:, or WARNING: or ERROR:.

Someone in your organisation has added the logic to do that. Talk to your SAS administrator to see if there is any way to switch them off.

Try system options ERRORS=0 :

options errors=0;
data x;
set sashelp.class;
x=input(sex,best.);
run;

10   options errors=0;
11   data x;
12   set sashelp.class;
13   x=input(sex,best.);
14   run;

NOTE: 达到 ERRORS= 选项设置的限制。系统将不打印该类型的其他错误。
