data a;
input a $5.;
datalines;
hello
howru
;

proc sql;
select a into :id separated by ',' from a ;
quit;


data _null_;
call system('export var="&id."');

I have created samp.sh program , here i am executing the sample.sas program and print the output from SAS program in UNIX environment. I am not getting the result.

*shell Script:

might try replacing
call system('export var="&id."');
with
call system("export var=""&id.""");
If the shell script command "export" supports single quotes, then use
call system("export var='&id.'");

Maybe You can code like this:
[pre]


data a;
input a $5.;
datalines;
hello
howru
;
run;
data _null_;
set a end=last;
file '/usr/bin/ksh/samp.sh';
length id $ 500;
retain id;
id=catx(' ',a);
if last then do;
envir_var='export var='||id;
put envir_var;
end;
run;

[/pre]

The reason why this is so difficult is because environment variables are inherited by the child process but the parent process is unaffected by the child process.
