A filename cannot contain any of the following characters: \ / : * ?  < > |. 1  Those characters have a functional meaning that affects the operating system's handling of the files and even recognizing that there is even a file if it had to encounter such a filename. I imagine you could rename within some version of Linux for example, but then I imagine you'd produce a file that Windows would hang up on.
These two files play an important role: / 1 etc/cron.allow - If this file exists, it must contain your username for you to use cron jobs. / 2 etc/cron.deny - If the cron.allow file does not exist but the /etc/cron.deny file does exist then, to use cron jobs, you must not be listed in the /etc/cron.deny file.
