HP-UX

if I insert the CD in HP Unix 11 how can I amount it and see its contents using command line ???

Try
#mount -F cdfs /dev/dsk/c#t#d# /cdrom

Also see these links.

You would mount the CD-ROM as showed by Awadhesh
(but usually you may omit specifying the filesystem)
The only tricky part is to know the device file of your CD-ROM drive.
ioscan could show you
(you may omit the pipe to more if you have only few disks attached to your box)

# ioscan -knfCdisk | more

Usually the CD drive will appear at the beginning of the ioscan dump.
Read the block device and use it in the mount command.

If you mount an HP-UX application CD there will be usually an ASCII file called
CD_TABLE_OF_CONTENTS
which lists all the programs on the CD set along with their depot specifyer,
a short description, and probably most important on which CD it is on.
Then you will have to
# umount /cdrom
(note, cd / if you get device busy)
and repeat the mount after having inserted the right CD.
Note the CD tray will be locked as long as the CD is mounted.
So to open it you need to first umount the CD.
