Hello -
I have a requirement to get the Memory(Xmx) and the activity name using it.
Sample input info :
Command running for the o/p:
Result looking from it (or something similar/meaningful):
Few pointers :
All these are running under process: rather
The memory is looking under value "Xmx"
always the activity name is after "/opt/rather/"
Hi,
I am confused about the output of find command.
Please see the two find commands below.
When i put "*.c" i get lots of files. But when i put *c only i get only one file.
Any answer??
$ find . -name "*c"

when I do the find command from / , there are a lot of directories that I do not have access to and so I get
"find: cannot open ..."
How can I suppress these messages so only what was found is output.
I was thinking on
find / -name 'searchterm' | grep -v find
but this doesnt work

Hi,
I am triying to make sure that there exists only one file with the pattern abc* in path /path/. This directory is having many huge files. If there is only one file then I have to take its complete name only to use furter in my script.

HI All,
Can anyone send me a command to find TOP 5 Memory consuming process.
It would be lelpful if I get output something like below

I tried few commands from the internet but the result only give the real memory usage or pagging, I want total... (4 Replies)
Hi all,
I found like top command could be used to find the Memory and CPU utilization. But i want to know how to find the Memory and CPU utilization for a particular user using top command.
Thanks in advance.
Thanks,

Hi guys -
I am trying a small script to tell me if there is a file that exists less than 1k. It should report ERROR, otherwise the check is good.
I wrote this script down, however it never runs in the if/then statement. It always returns the echo ERROR.

Hi All,
I wanted to show on stdout that a file was found right after it happens due to indicate the activity of long search. Further more I want to store the result of the find in a file.
I have tried this:

I wanted to know how to find the memory taken by a process using top command. The output of the top command is as follows as an example:
Mem: 13333364k total, 13238904k used, 94460k free, 623640k buffers
Swap: 25165816k total, 112k used, 25165704k free, 4572904k cached

vmstat
vmstat(1) General Commands Manual vmstat(1)Name
vmstat - report virtual memory statistics
Syntax
vmstat [ interval [ count ] ]
vmstat -v [ interval [ count ] ]
vmstat -fKSsz
vmstat -Kks namelist [ corefile ]
Description
The command reports statistics on processes, virtual memory, disk, trap, and cpu activity.
If is specified without arguments, this command summarizes the virtual memory activity since the system was last booted. If the interval
argument is specified, then successive lines are summaries of activity over the last interval seconds. Because many statistics are sampled
in the system every five seconds, five is a good specification for interval; other statistics vary every second. If the count argument is
provided, the statistics are repeated count times.
When you run the format fields are as follows:
Procs: information about numbers of processes in various states.
r in run queue
b blocked for resources (i/o, paging, and so on.)
w runnable or short sleeper (< 20 seconds) but swapped
faults: trap/interrupt rate averages per second over the last 5 seconds.
in (non clock) device interrupts per second
sy system calls per second
cs cpu context switch rate (switches/second)
cpu: breakdown of percentage usage of cpu time
us user time for normal and low priority processes
sy system time
id cpu idle time
Memory: information about the use of virtual and real memory. Virtual pages are considered active if they belong to processes which are
running or have run in the last 20 seconds.
avm active virtual pages
fre size of the free list
Pages are reported in units of 1024 bytes.
If the number of pages exceeds 9999, it is shown in a scaled representation. The suffix k indicates multiplication by 1000 and the suffix
m indicates multiplication by 1000000. For example, the value 12345 appears as 12k.
page: information about page faults and paging activity. These are averaged every five seconds, and given in units per second. The size
of a unit is always 1024 bytes and is independent of the actual page size on a machine.
re page reclaims (simulating reference bits)
at pages attached (found in free list not swapdev or filesystem)
pi pages paged in
po pages paged out
fr pages freed per second
de anticipated short term memory shortfall
sr pages scanned by clock algorithm, per-second
disk: s0, s1 ...sn: Paging/swapping disk sector transfers per second (this field is system dependent). Typically paging is split across
several of the available drives. This will print for each paging/swapping device configured into the kernel.
Options-f Provides reports on the number of forks and vforks since system startup and the number of pages of virtual memory involved in each
kind of fork.
-K Displays usage statistics of the kernel memory allocator.
-k Allows a dump to be interrogated to print the contents of the sum structure when specified with a namelist and corefile. This is
the default.
-S Replaces the page reclaim (re) and pages attached (at) fields with processes swapped in (si) and processes swapped out (so).
-s Prints the contents of the sum structure, giving the total number of several kinds of paging related events that have occurred since
boot.
-v Prints an expanded form of the virtual memory statistics.
-z Zeroes out the sum structure if the UID indicates root privilege.
Examples
The following command prints what the system is doing every five seconds:
vmstat 5
To find the status after a core dump use the following:
cd /usr/adm/crash
vmstat -k vmunix.? vmcore.?
