Hi ,
I do have a fixedwidth flatfile that has data for 10 different datasets each identified by the first two digits in the flatfile.
01 in the first two digit position refers to Set A

I want to genrate 10 different files from my... (6 Replies)
Hello, I have a large file (2GB) that I would like to split based on pattern and size.
I've used the following command to split the file (token is "HELLO")
awk '/HELLO/{i++}{print > "file"i}' input.txt
and the output is similar to the following (i included filesize in KB):

I have a file that is about 7 GB in size. The requirement is I should split the file equally in such a way that the size of the split files is less than 2Gb. If the file is less than 2gb, than nothing needs to be done. ( need to done using shell script)
Thanks, (4 Replies)

pmc_control
PMC_CONTROL(2) BSD System Calls Manual PMC_CONTROL(2)NAME
pmc_control, pmc_get_info -- Hardware Performance Monitoring Interface
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/pmc.h>
int
pmc_control(int ctr, int op, void *argp);
int
pmc_get_info(int ctr, int op, void *argp);
DESCRIPTION
pmc_get_info() returns the number of counters in the system or information on a specified counter ctr. The possible values for op are:
PMC_INFO_NCOUNTERS
When querying the number of counters in the system, ctr is ignored and argp is of type int *. Upon return, the integer pointed to by
argp will contain the number of counters that are available in the system.
PMC_INFO_CPUCTR_TYPE
When querying the type of a counter in the system, ctr refers to the counter being queried, and argp is of type int *. Upon return,
the integer pointed to by argp will contain the implementation-dependent type of the specified counter.
If ctr is -1, the integer pointed to by argp will contain the machine-dependent type describing the CPU or counter configuration.
PMC_INFO_COUNTER_VALUE
When querying the value of a counter in the system, ctr refers to the counter being queried, and argp is of type uint64_t *. Upon
return, the 64-bit integer pointed to by argp will contain the value of the specified counter.
PMC_INFO_ACCUMULATED_COUNTER_VALUE
When querying the value of a counter in the system, ctr refers to the counter being queried, and argp is of type uint64_t *. Upon
return, the 64-bit integer pointed to by argp will contain the sum of the accumulated values of specified counter in all exited sub-
processes of the current process.
pmc_control() manipulates the specified counter ctr in one of several fashions. The op parameter determines the action taken by the kernel
and also the interpretation of the argp parameter. The possible values for op are:
PMC_OP_START
Starts the specified ctr running. It must be preceded by a call with PMC_OP_CONFIGURE. argp is ignored in this case and may be NULL.
PMC_OP_STOP
Stops the specified ctr from running. argp is ignored in this case and may be NULL.
PMC_OP_CONFIGURE
Configures the specified ctr prior to running. argp is a pointer to a struct pmc_counter_cfg.
struct pmc_counter_cfg {
pmc_evid_t event_id;
pmc_ctr_t reset_value;
uint32_t flags;
};
event_id
is the event ID to be counted.
reset_value
is a value to which the counter should be reset on overflow (if supported by the implementation). This is most useful when
profiling (see PMC_OP_PROFSTART, below). This value is defined to be the number of counter ticks before the next overflow.
So, to get a profiling tick on every hundredth data cache miss, set the event_id to the proper value for ``dcache-miss'' and
set reset_value to 100.
flags Currently unused.
PMC_OP_PROFSTART
Configures the specified ctr for use in profiling. argp is a pointer to a struct pmc_counter_cfg as in PMC_OP_CONFIGURE, above. This
request allocates a kernel counter, which will fail if any process is using the requested counter. Not all implementations or coun-
ters may support this option.
PMC_OP_PROFSTOP
Stops the specified ctr from being used for profiling. argp is ignored in this case and may be NULL.
RETURN VALUES
A return value of 0 indicates that the call succeeded. Otherwise, -1 is returned and the global variable errno is set to indicate the error.
ERRORS
Among the possible error codes from pmc_control() and pmc_get_info() are
[EFAULT] The address specified for the argp is invalid.
[ENXIO] Specified counter is not yet configured.
[EINPROGRESS] PMC_OP_START was passed for a counter that is already running.
[EINVAL] Specified counter was invalid.
[EBUSY] If the requested counter is already in use--either by the current process or by the kernel.
[ENODEV] If and only if the specified counter event is not valid for the specified counter when configuring a counter or starting
profiling.
[ENOMEM] If the kernel is unable to allocate memory.
