if directory exists create a file else check if it is a symlink

In most nodes, the /usr/share/tomcat7/lib directory exists and placing a jar inside that works fine. But on few nodes, instead of that directory, there is a symlink to /usr/share/java/tomcat7 exist. So create a file inside the directory /usr/share/tomcat7/lib fails. How do I create the file in the correct directories based on the symlinks. 1) If symlink exists, create jar files in the linked folder(eg: /usr/share/java/tomcat7) 2) If there's no symlink and just a direct directory, create the file in that directory(eg: /usr/share/tomcat7/lib) Please provide examples. node1:mydata/myfolder #ls -lah /usr/share/tomcat7/lib lrwxrwxrwx 1 root root 23 Aug 17 15:44 /usr/share/tomcat7/lib -> /usr/share/java/tomcat7 Thanks in advance. P.S: I found some links => manage examples in the web, but not sure how to add both test cases together to bring up an optimum solution.
