Re: Cygwin and (Linux or Unix) env: running applications

Thank you Igor,

Your suggestion was good, but did not resolve the problem. Somehow SAS 
was still missing the command by not invoking the symbolic links. After 
many trials here is the solution in case someone else has a similar problem:

Through SAS I created a run.sh file in which I added the following lines:

#! /usr/bin/tcsh

### run.sh file

splus70 /BATCH c:\\aldi2\\splus_test\\batch.txt c:\\aldi2\\splus_test\\batch.out c:\\aldi2\\splus_test\\batch.err


In SAS under a macro I do the following:

%sysexec chmod +x c:\aldi2\splus_test\run.sh;

%syexec tcsh c:\aldi2\splus_test\run.sh ;

Now SAS and Splus can run automatically in batch mode in my PC under 
cygwin by recognizing cygwin symbolic links.
Best,

Aldi
