Open two windows in Ubuntu, and list the content of the /dev/fd folder. Can you explain the difference observed from the two windows? The name /dev/fd is actually a symbolic link to /proc/self/fd. The name self is also a symbolic link pointing to a number, which is the process ID of the current process. Therefore, the number pointed to by self is different if viewing from different windows.
