How can we print the entries in /etc/cron.d  through commnad line as it not
showing any entries  crontab -l as the entry in /etc/cron.d is for root
user .

The entries in /etc/cron.d should look very similar to what you see in /etc/crontab -- basically, everything in /etc/cron.d/ are just additional fragments of a greater crontab that includes /etc/crontab and every file in /etc/cron.d/. If you just 'cat /etc/crontab /etc/cron.d/*' you'll see all the non-user crontab entries.

I'll note that running 'crontab -l' as root *DOES NOT* show the entries in /etc/crontab, but rather the entries in /var/spool/cron/root. The syntax for the root crontab differs from the /etc/crontab and /etc/cron.d/* entries. In the user crontabs, you don't need to list the user in the sixth column, since that is implied. That user is required in the system-wide crontab files.
