What is command to see logfile ?

Hi everyone,
I used to use this :
"tail -f /var/log/messages" to see what is going on in my unix box, but when i log in Mac OS X server as root then type that command , it doesn't work. Anyone know ? I'm newbie to this.
By the way, are there any pages about Mac OS X server command ? thanks.
Mac OS X (10.4.4)

Hi
In addition to what has already been added
cd /var/log
ls
more system.log [or any other log you are interested in]
Down arrow or return will keep on spooling the log until you are done. Control C followed by exit will get you out of it.
You can also get the Command Line Manual for 10.4 here:
http://manuals.info.apple.com/en/CommandLinev10.4.pdf
and also a lot more manuals from here:

What is the command to see the database

what is the command to see the database?iam using oracle express edition in that i tried to create a database but it showing database already created.
i need to check which database is created.

Probably you are thinking that Oracle database is a kind of file something like which we sees other files like .txt, .doc, .pdf etc which we sees by ls or dir commands. Of course there are files for Oracle database, but they have their own nomenclature and setup which finds in C:\oraclexe\oradata\XE\ (For example in Windows) or /usr/lib/oracle/xe/oradata/XE/ (For example in Linux).
By default, the database is started for you after installation and every time your computer is restarted. However, to reduce the overall performance load on the system, you can manually stop the database, and then manually restart it later.
Oracle&reg; Database Express Edition
Ok, now if you wish to login to the database (we don't says "see" the database, because database is different thing than a picture or image ), you just open your command window and say :
sqlplus sys/your_password_of_sys_user as sysdba
If you get SQL> prompt, you have logged in the database as sys user and this is your database.
If you wish to login with different user then you can :
1.login from command window by sqlplus username/password
2.login from SQL> prompt by connect username/password

Hello:
What logfiles are you refering to?
database logs (i.e.: alert.log... user dumps?)?
Their location can be queried from sqplus:
XE>show parameter dump_dest
NAME                                 TYPE        VALUE
background_dump_dest                 string      /usr/lib/oracle/xe/app/oracle/
                                                 admin/XE/bdump
core_dump_dest                       string      /usr/lib/oracle/xe/app/oracle/
                                                 admin/XE/cdump
user_dump_dest                       string      /usr/lib/oracle/xe/app/oracle/
                                                 admin/XE/udumpListener's log can be queried with 'lsnrctl status' command:

What hide command will do

what hide command will do

Here is the F1 help.....
<i>HIDE
Basic form
HIDE f.
In an ABAP Objects context, a more severe syntax check is performed that in other ABAP areas. See Constants not allowed in HIDE area.
Effect
Retains the contents of f related to the current output line. When the user selects the line from the list f is automatically filled with the retained value.
The selection can occur in:
AT LINE-SELECTION
AT PFx
AT USER-COMMAND
READ LINE
The contents of the field do not have to have been displayed using WRITE in order for you to retain them.
The HIDE statement does not support deep structures (structures that contain internal tables).
Useful system fields for interactive reporting are listed in the System Fields for Lists documentation.
Note
Lines or components of lines of an internal table that you address using a field symbol (see ASSIGNING addition to the READ and LOOP statements), cannot be retained using HIDE. You can store them using a global variable instead.
Note
Runtime errors:
HIDE_FIELD_TOO_LARGE: The field is too long for HIDE.
HIDE_ON_EMPTY_PAGE: HIDE not possible on an empty page.
HIDE_NO_LOCAL: HIDE not possible for a local field.
HIDE_ILLEGAL_ITAB_SYMBOL: HIDE not possible for a table line or component of a table line.</i>
and also a sample program.
report zrich_0003.
data: begin of itab occurs 0,
field type c,
end of itab.
itab-field = 'A'. append itab.
itab-field = 'B'. append itab.
itab-field = 'C'. append itab.
itab-field = 'D'. append itab.
itab-field = 'E'. append itab.
loop at itab.
format hotspot on.
write:/ itab-field.
hide itab-field.
format hotspot off.
endloop.
at line-selection.
write:/ 'You clicked', itab-field.
It kind of "remembers" what is written, so that when you click on it, it knows what the value is.
Please remember to award points and mark as solved if your question has been answered. Thanks.

HT1399 I was able to see the lyrics while playing the audio when my iOS was 6.1.4 now i do not know what to do to see the lyrics while playing the audio or a karaoke

I was able to see the lyrics while playing the audio when my iOS was 6.1.4
now i do not know what to do to see the lyrics while playing the audio or a karaoke after upgraded(?) to iOS 7
Is there any chance to see the lyrics in iOS 7 or i want to degrade it to 6.1.4?

Thank you for responding. I'm not sure if my complete original message came through. It was just today that an automatic update notice came through, and I installed the update that was offered. So I have to guess that version — 10.1.10 — is the latest version that's available to me. My OS is 10.6.8. Again (in case the complete message isn't appearing), I'm on an older Mac, specifically MacBook 2.1. Perhaps this is the problem, and I never should have updated a few years ago. If so, I wonder if there's any way I can go back to that earlier version that worked well for me, rather than the last few versions, which have not.

Command to see the memory ,cpu etc.

Anyone can tell me the command to see the memoery usage ,cpu usage etc ,like the 'top ' command in unix.
Please reply.

Assuming you're using Solaris 8 or above try prstat
prstat -am will show more or less the same output as TOP.
There's also commands such as swap -l and swap -s, vmstat, mpstat, iostat which can be used to monitor performance as well.
