There are so many commands. Start by reading man man pages. First understand how man pages are grouped into different sections. Like certin commands are only for sysadmins, some refer to system calls etc.

man man

Also, start reading basic unix books, then you can move onto HP-UX books. A book by Rafiq-Ur-Rehman is best for hp-ux.

Hi Akashvenkat,

The are many commands in hp unix and each command is important in it's arena..

Man command is the best practice to teach urself.
#man ( for example man ls)

If possible, try to arrange some book published by hp.

cheers

Hi,

I think most of HP-UX commands are important, but you need to get to use it so you will find which one is suitable for your daily tasks.

If you would like to find the details about the command, just search the man page of that command.

You can go for HP-UX Sys Admin training or just read from the books.

Poniatowski is a good book for start. The one that I use for the first time is 'HP-UX 11i System Administration Handbook and Toolkit'. And also from Rehman.

Below are some books for references :

HP-UX
Cooper/Moore HP-UX 11i Internals
Fernandez Configuring CDE
Madell Disk and File Management Tasks on HP-UX
Olker Optimizing NFS Performance
Poniatowski HP-UX 11i Virtual Partitions
Poniatowski HP-UX 11i System Administration Handbook and Toolkit, Second Edition
Poniatowski The HP-UX 11.x System Administration Handbook and Toolkit
Poniatowski HP-UX 11.x System Administration "How To" Book
Poniatowski HP-UX 10.x System Administration "How To" Book
Poniatowski HP-UX System Administration Handbook and Toolkit
Poniatowski Learning the HP-UX Operating System
Rehman HP-UX CSA: Official Study Guide and Desk Reference
Sauers/Ruemmler/Weygant HP-UX 11i Tuning and Performance
Weygant Clusters for High Availability, Second Edition
Wong HP-UX 11i Security

Hope this information can help you.

Cheers,
AW

Hi,

There are lots of documentations available in the net. I recommend you to lern module by module, rather than just muggingup the commands. That is no way going to help you.
What best you can do is to classify the hpux system in to diffrent modules and gp thorugh one by one, prepare a small note of commands and it'd discr. Some think like

UNIX has some thing called man pages, this is an online help available in the system. practice to get help from man.

Shalom Akashvenkat,

My advice is spend and hour a day reading threads and various questions in this very forum.

You will see a lot of commands to deal with issues both mundane and complex.

You might also like to get a book called HP Certified by Rehman, it provides a good learners background.

Lastly, you can see if HP Education offers courses near your locale. I loved all the courses I took at HP and learned a lot.

Hi Akashvenkat ,

Just start with $ man man , and you got the key to all.

The commands are huge , and every command is useful for their particular use. And many unix commands are same , except few changes . for hp-ux commands check this link:

http://docs.hp.com/en/5971-2523/5971-2523.pdf

Also go through the hp-ux sysadmin books , that will help :

Here is one:

Hi Akashvenkat ,

Here is few things , that might help you :

1. User Administration:

# useradd -u uid -s /usr/bin/ksh -g pri_group -d /home/username -m username
[ Where uid , pri_group , username : are input ]

# passwd username # setting password.
# passwd -f username # to chg pw at next login.

# usermod -G grp1 grp2 username # to add more group for the user ]

# passwd -l username # To lock a user ]

You can do the same activity through sam also.

2. System Maintenance:

1. To shutdown :
(Make sure nobody working and system needs to shutdown , check oracle and other application stopped.)

# ps -ef | egrep '(ora|pmon)' # to check if oracle running.)

Check Application team before shutting down.

To shutdown for any maintenace or other reason:
# shutdown -h -y 0

To Reboot: ( To watch the reboot, make sure you have logged in GSP/console)
# reboot -r -y 0

To boot in single user mode:
Interrupt normal boot process:
at ISL > hpux -is

3. To check System Logs:
/var/adm/syslog/syslog.log
dmesg
/var/opt/resmon/log/event.log
/var/adm/wtmp , utmp , btmp #login logs.
/var/adm/mail.log # mail log
/var/adm/cron/log # cron log
/var/adm/lp/log # LP logs.
/var/adm/sw/swinstall.log # All sw logs can be found here.
/var/adm/crash # crash dumps.

4. System / devices :
# ioscan -fnC disk # to check disks.
# ioscan -fnC tape # to check tape devs.
# ioscan -fnC lan # to check lan devs.

# /opt/resmin/bin/resls / # To check resources configured

5. System Backup/Restore:

tar
cpio
make_tape_recovery *Important.

( Use man page to see details.)

6. Kernel tuning:

# kmtune -q parameter # to see current value.
# kmtune -s npty=120 # [Ex: to change npty value ]
# ./mk_kernel
