I have two questions. The first one is whether it is possible for a file
to have different names under bash and csh. In my department's system I came
across a strange thing that a folder is called "\r" under
bash and called "?" under csh. The second one is that in shell scripts
whether there is a difference between "/''*" and "/*". What are the use of
two double single quotes in the "/''*". Aren't they redundant? The shell
script "startx" has the expression "/''*".
Any response will be much appreciated.
