Hmm, you speak about a "/../vob" directory and your script does a chdir to '"/view/conflictcheck.view1/vobs/app_bos"'. You have "vob" on the one hand and "vobs" on the other (Is it singular or plurial?). And, in addition, you chdir not to the vob or vobs directory, but to a subdirectory of "vobs". Could it be that this is the simple error barring you from running your script? Just my 2 cents...
Yes it is vobs and the sub directory is where the files I need to run the cleartool find command. I get an output but as if it was ran outside of the vobs directory. Output with files can not be found. As if it can not find the files.
What you have should work. It's unclear if the view "conflictcheck.view" was started and the vob was mounted when your script ran. If that were the case then it would seem like the vob was empty. How about doing the chdir then do an system('ls') to see if your script sees files after the chdir? It should. If not then the chdir failed (but you do error out if that happens). If there are no files then start another window and cd to that directory there. If the new shell window shows files but your script doesn't then there's something else wrong.
