Thank you It worked. I guess get line should be "getline"
Yes. I apologize. I installed a security update to my browser last weekend, and the spell checker is apparently much more aggressive at fixing (supposed) mistakes (even after I have told it not to change something I typed). For some reason it thought it should change shmmax to shammy and when I went back in to fix that, it silently also changed getline to get line. I'm going to have to watch it more closely (or disable it).
It looks like RudiC's suggestion was also mangled by something... The line he suggested:
Code:
/^kernel.printk/ {$3 = shmmax
should be:
Code:
/^kernel.shmmax/ {$3 = shmmax

I'm in the process of writng a function that consists of a case statement is there a way of calling the function and passing a value to it?
ie

case
opt1 do .....
opt2 do.....
esac

function opt1
I'm aware the syntax is not correct, but you get the general idea. (1 Reply)

suppose i have a perl script that is normally run this way:
./checkdisk.pl -H hostname -w 40 -c 80
but, for whatever reason, i cannot run the script directly as it should. But i can cat it through pipe. How can i pass the arguments "-H hostname -w 40 -c 80"?
so this is what i'm doing,... (6 Replies)

shmmni
shmmni(5) File Formats Manual shmmni(5)NAME
shmmni - number of System V shared memory segment identifiers in the system
VALUES
Default
Allowed values
DESCRIPTION
Shared memory is an efficient InterProcess Communications (IPC) mechanism. One process creates a shared memory segment and attaches it to
its address space. Any processes looking to communicate with this process through the shared memory segment then attach the shared memory
segment to their corresponding address spaces as well. Once attached, a process can read from or write to the segment depending on the
permissions specified while attaching it.
This tunable effectively sets the number of unique segments creatable system wide, since each segment is assigned an identifier by the ker-
nel. The identifier is simply a reference generated by the kernel such that any user process can request a particular segment for sharing
with a simple integer, and let the kernel determine which segment this corresponds to.
Who is Expected to Change This Tunable?
Anyone.
Restrictions on Changing
Changes to this tunable take effect immediately.
Attempting to lower below the current number of identifiers in use or below the current value of will result in an error message.
Attempts to raise the value of when insufficient memory is available to the kernel to create the needed structures will result in an error
message.
When Should the Value of This Tunable Be Raised?
should be raised if users of System V shared memory are receiving the error message on calls.
What Are the Side Effects of Raising the Value?
Kernel memory usage will be slightly increased, as the data structures used to track the segments are allocated based on this tunable.
When Should the Value of This Tunable Be Lowered?
If kernel memory is at a premium, or it is known that few segments will be needed, a slight savings can be gained from decreasing this tun-
able, and thus decreasing the data structure memory usage associated with it.
What Are the Side Effects of Lowering the Value?
Kernel memory usage will be slightly reduced.
What Other Tunable Values Should Be Changed at the Same Time?
and should be considered. should be changed in the same manner as since lowering the total number of segments but raising the number
available per process only makes sense if you want a few processes taking all the segments.
is more complex and any changes to it really depend on the effect desired. Refer to the shmmax(5) manpage for more information before
changing this tunable.
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of
HP-UX.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
factory installed on your system, see at
