It looks to me like the /usr/bin/clear isn't needed at all. Right below that, he's got the lineprintf "\e[2J\e[H" > /etc/issue whicl will clobber /etc/issue, including anything that "clear" appended to it.
I think that he wants to clobber with the clear command (and thereby make the first character of /etc/issue a control character that clears the screen). Using TERM=linux where I have inserted it will solve the TERM environment variable not set error. (Use of TERM=linux should be preferred over TERM=vt100, because you know practically for certain that /etc/issue will only be printed to the linux console)
My suggestion regarding this:
YELLOW="\033[1;33m" # Light Red
- /usr/bin/clear >> /etc/issue - printf "\e[2J\e[H" > /etc/issue + TERM=linux /usr/bin/clear > /etc/issue + printf "\e[2J\e[H" >> /etc/issue echo -e " " >> /etc/issue
As for your other problem, the username field is only used in the global crontab, and is never used in the crontab that you edit using `crontab -e`. As a result, "root" is being interpreted as a command, not a username. Login as root and run crontab -e, or run
sudo crontab -e. Set up the cronjob there.
