My sys admin has set couple paths at .cshrc_global and I don't have permission to edit the file.
How can I add my own path? If I type set path = ( ~/usr/local/bin ), this will set path ONLY to
my ~/usr/local/bin and the old paths that have been assigned by my sys admin will be deleted.
My 2nd question is: I hate to type ./my_executable_file everytime. How can I make the program runs
when I just type my_executable_file without ./ ?
