ABAP Adaption while migrating from Windows to Unix

Dear All,

I am working on a project where SAP system has been migrating from Windows to Unix os. Because of this all ABAP which are using Files, Operating system command has to be adapted as well.

How can I get such a list of ABAP objects which will be affected by this migration.

Example I can look for Dataset command, External OS Commands and so on..

Please advice if there is a straight forward way to get such a list?

Your prompt response would be higly appreciated.

Thanks in Advance
