In BigSur Beta, when I try to open a file using open file:////Users/<username>/Desktop/<filename.txt> the command is internally converted by prefixing the current working directory in terminal to the given value. For eg., if the current directory is "/Users", the command is converted into open /Users/file:////Users/<username>/Desktop/<filename.txt> This obviously gives an error unable to find the file. This happens even if I give a folder name instead of filename in file URI format. http scheme works fine and no prepending happens. For eg., open http://<url> redirects to safari cleanly Note: I understand from the man page, that whenever we give a non-absolute file/folder names to open command, it prepends the current directory to the given value. However this prepending should not happen in case the value starts with a file URI scheme (similar to how values starting with http is handled). This is working fine till Catalina and is present only in BigSur betas. Can someone confirm this behaviour.
