8 character limit for ipcs command , any way to increase # of chars ?
Hello All,
We have a working script which identifies and kills ipcs resources which havent been correctly killed during normal shutdowns.
It is working fine and dandy however there are some issues now.
Our target search string has increased by 1 character from 8 chars to 9. What I am observing @ this point is the ipcs -a | grep (9 char string) is returning blank results. The increase in characters is due to new naming conventions. So while it may be easy to say , "simply use an 8 char database", in practicality it is over my head.
Desired Solution:
I need to find a way to get ipcs to be able to identify resources associated with a 9 char search string. From what I have read so far I havent dug up an environment var or quick fix for this issue. I have also dug through a few posts here in the forum in the hopes of finding a solution.
Code Example:
a) Working:
Code:
ipcs -a | grep 1245678
b) Not working
Code:
ipcs -a | grep 123456789
Anything you can offer is appreciated!
There are logic tweaks I can make to the script however out of curiosity I would like to learn more about ipcs on solaris. Constantly hungry for skills!
Thank you!

Hi,
I read the ipcs man page and am still very confused.
Basically, I just want to know whether the output from the ipcs command below means these are the current "TOTAL" memory usage in bytes on the server? Is this correct?
Thanks in advance.

Hi
I would just like to ask if there is a way for UNIX to ignore/overcome the 255 character limit of the command line?
My problem is that I have a really long line of text from a file (300+ bytes) which i have to "echo" and process by adding commands like "sed" to the end of the line, like... (5 Replies)

ipcs - show information on IPC facilities
SYNOPSIS
ipcs [options]
DESCRIPTION
ipcs shows information on the inter-process communication facilities for which the calling process has read access. By default it shows
information about all three resources: shared memory segments, message queues, and semaphore arrays.
OPTIONS -i, --id id
Show full details on just the one resource element identified by id. This option needs to be combined with one of the three
resource options: -m, -q or -s.
-h, --help
Display help text and exit.
-V, --version
Display version information and exit.
Resource options
-m, --shmems
Write information about active shared memory segments.
-q, --queues
Write information about active message queues.
-s, --semaphores
Write information about active semaphore sets.
-a, --all
Write information about all three resources (default).
Output formats
Of these options only one takes effect: the last one specified.
-c, --creator
Show creator and owner.
-l, --limits
Show resource limits.
-p, --pid
Show PIDs of creator and last operator.
-t, --time
Write time information. The time of the last control operation that changed the access permissions for all facilities, the time of
the last msgsnd(2) and msgrcv(2) operations on message queues, the time of the last shmat(2) and shmdt(2) operations on shared mem-
ory, and the time of the last semop(2) operation on semaphores.
-u, --summary
Show status summary.
Representation
These affect only the -l (--limits) option.
-b, --bytes
Print sizes in bytes.
--human
Print sizes in human-readable format.

The Linux ipcs utility is not fully compatible to the POSIX ipcs utility. The Linux version does not support the POSIX -a, -b and -o
options, but does support the -l and -u options not defined by POSIX. A portable application shall not use the -a, -b, -o, -l, and -u
options.
