Hack 7.8 Getting The Process ID (PID) On UNIX and Linux

SAS Programming Professionals,

Did you know that you can use &SYSJOBID to get the Process ID (PID) of SAS tasks running on UNIX and Linux servers? 

This can be useful for differentiating between multiple SAS sessions you have running on a UNIX or Linux server.  It is also useful when you want to correlate the PID of a particular SAS batch task with UNIX or Linux system performance information. 

Here is an example of using &SYSJOBID that I have coded in many of my SAS/Connect programs:

data _null_;

pid     = &SYSJOBID;

put '******************************************************';

put '*                                                    *';

put '*The Process ID of this SAS/Linux Session is: ' pid '*';

put '*                                                    *';

put '******************************************************';

run;

This code produced the following in the SAS log when running from a PC client to a Linux server:

******************************************************

*                                                    *

* The Process ID of this SAS/Linux Session is: 31037 *

*                                                    *

******************************************************

It might make sense to use &SYSJOBID to document the PID of all of your SAS programs running in UNIX environments.  That way; you will always have that information in your SAS log if you ever need it. 

Best of luck in all your SAS endeavors!
