Thanks Made in Germany and Carlos for your input... Now I understand what Carlos meant... Yes echoing the $line works ... That was confusing me as why the why loop goes into the awk subshell...you guys cleared that.
For this script I will use variables as suggested by Don as that is a simpler approach.
regarding the additional checks that you proposed </dev/null work fine but I run into some issues using -f option for su and the 'ticks'... With -f option for su it looks like I can't use -R for chmod(my original script did not have -R for chmod but now I added it) and I get
With the 'ticks' looks like it can't resolve the variable(which is what i thought)

Reason: Switch ICODE tags to CODE tags and remove extraneous spaces.

The error message you showed above should not be printed as a result of using the command:
The double quotes around the string whoami; chmod 777 /saswork/sastemp/'$sas_work_dir' make the single quotes regular characters with no special meaning, so $sas_work_dir should be expanded before su is invoked. Assuming as an example that $sas_work_dir expands to some/dir), the shell should invoke su with a final operand that is the string whoami; chmod 777 /saswork/sastemp/'some/dir' and the shell that su invokes would then remove those single quotes.
Please show us the exact command line that you are using to invoke su.
Actually you and Don are right.. single quotes within double quotes are not causing any error.
I must have done somethign wrong the first time when I tested and got the error about not finding the directory..I tested again with single quotes around the '$sas_work_dir' and it worked fine thsi time..
Do you use the contents of the files named by $SASWORK_LIST_ALL_BEFORE and $SASWORK_LIST_SASWORK after this loop completes? If $SASWORK_LIST_ALL_BEFORE isn't used after this loop, the first egrep is superfluous and the code:
can be replaced by:
If $SASWORK_LIST_SASWORK isn't used after this loop either, then neither file is needed:
I actually do use SASWORK_LIST_BEFORE again. The script deletes the orphaned SAS work directories and afterwards it runs sdiff on SASWORK_LIST_BEFORE with SASWORK_LIST_AFTER.
Also another reason why I keep these files temoprarily(deleted at the end of the end of the script) is because I generate a report from these files.
