问题


When I use Sys.chmod(file,'777') it looks like the permission is changed only for the owner and not for all users, how can I do this ?


回答1:


Disable the umask check in Sys.chmod to get what you want:

Sys.chmod(file, "777", use_umask = FALSE)

Alternatively use system directly:

system('chmod 777 file')
