How to run SAS program in UNIX Bash shell script?

I am trying to run .SAS program (test1.SAS) from Unix Bash shell script file. Please let me know what I am doing wrong in my Bash shell script or in my  .SAS program code.

Note: SAS dataset "dataset1.sas7bdat" does exist in the "testing" directory in Unix.

Unix Bash shell script

#script - tmp1.sh
#!/bin/bash
mydir=/2011/march/tuesday/testing
export mydir
sas=/products/SAS/SASFoundation/9.2/sas
$sas test1
exit

Open in new window



SAS

#filename test1.sas
libname lib "$mydir";
data lib.dataset2;
   set lib.dataset1;
   if _N_ < 10 then output;
run;

Open in new window


Are there any other ways to run SAS programs (with SAS datasets) from Unix bash shell script?

you'll need to use the sysin parameter:
-sysin [filename.sas]

i can't remember if you can trigger a sas session by just sas, or if sas.sh is needed, but it should look like:
> sas -sysin test1.sas

or

> sas -sysin [full path]\test1.sas

there are other options you can include like -autoexec, -log etc

Thank you very much, lowaloysius!!

I will definitely try your way trigger SAS as well, but is it OK to reference  "mydir" logical as I did in the test1.SAS?
libname lib "$mydir";

Open in new window


Also, what if I want to reference a directory with a file (.SAS, .DAT, or .sas7bdat), would it logically work?
 
Thank you!

no it won't work... that is a UNIX variable which you are trying to use in a SAS session...

like i mentioned in my other answer, that's AFAIK... i'll be glad if a fellow expert proves me wrong on this...
