Hi,
I have got a large number of .PDF files that are archived in .RAR & ZIP files in various directories and I would like to search for strings inside the PDF files.
I would think you would need something that can recursively read directories, extract the .RAR/.ZIP file in memory, read the... (3 Replies)
HI All,
At present in my server the log folder was filled up and causing memory issue.
So I am planning to write a script in such a way that the files which are older than 30 days will be deleted and also need to find the files which were not compressed and need to compress this file.... (4 Replies)
Hi,
Is is possible to zip a folder and all its contents within the folder ( including sub-directories and files) into a zip file? and can regain the same structure if unzipped?

Hi Forum,
I am using the below command to find files older than x days in a directory excluding subdirectories. From the previous forums I got to know that prune command helps us not to descend in subdirectories. Though I am using it here, not getting the desired result.

Find all files in the current directory only excluding hidden directories and files.
For the below command, though it's not deleting hidden files.. it is traversing through the hidden directories and listing normal which should be avoided.
`find . \( ! -name ".*" -prune \) -mtime +${n_days}... (7 Replies)
Hi All,
requirement is to find and remove the files from sub directories but it should exclude the files from parent directory.
At present i am using the below one but it finds and remove files from both parent and sub directories.

Hi frnds,
My requirement is I have a zip file with name say eg: test_ABC_UH_ccde2a_awdeaea_20150422.zip
within that there are subdirectories on each directory we again have .zip files and in that we have files like mama20150422.gz and so on.
Iam in need of a bash script so that it unzips... (0 Replies)

mpi_alloc_mem
MPI_Alloc_mem(3OpenMPI)MPI_Alloc_mem(3OpenMPI)NAME
MPI_Alloc_mem - Allocates a specified memory segment.
SYNTAX C Syntax
#include <mpi.h>
int MPI_Alloc_mem(MPI_Aint size, MPI_Info info, void *baseptr)
Fortran Syntax (see FORTRAN NOTES)
INCLUDE 'mpif.h'
MPI_ALLOC_MEM(SIZE, INFO, BASEPTR, IERROR)
INTEGER INFO, IERROR
INTEGER(KIND=MPI_ADDRESS_KIND) SIZE, BASEPTR
C++ Syntax
#include <mpi.h>
void* MPI::Alloc_mem(MPI::Aint size, const MPI::Info& info)
INPUT PARAMETERS
size Size of memory segment in bytes (nonnegative integer).
info Info argument (handle).
OUTPUT PARAMETERS
baseptr Pointer to beginning of memory segment allocated.
IERROR Fortran only: Error status (integer).
DESCRIPTION
MPI_Alloc_mem allocates size bytes of memory. The starting address of this memory is returned in the variable base.
FORTRAN NOTES
There is no portable FORTRAN 77 syntax for using MPI_Alloc_mem. There is no portable Fortran syntax for using pointers returned from
MPI_Alloc_mem. However, MPI_Alloc_mem can be used with Sun Fortran compilers.
From FORTRAN 77, you can use the following non-standard declarations for the SIZE and BASEPTR arguments:
INCLUDE "mpif.h"
INTEGER*MPI_ADDRESS_KIND SIZE, BASEPTR
From either FORTRAN 77 or Fortran 90, you can use "Cray pointers" for the BASEPTR argument. Cray pointers are described further in the For-
tran User's Guide and are supported by many Fortran compilers. For example,
INCLUDE "mpif.h"
REAL*4 A(100,100)
POINTER (BASEPTR, A)
INTEGER*MPI_ADDRESS_KIND SIZE
SIZE = 4 * 100 * 100
CALL MPI_ALLOC_MEM(SIZE,MPI_INFO_NULL,BASEPTR,IERR)
! use A
CALL MPI_FREE_MEM(A, IERR)
ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument. C++ func-
tions do not return errors. If the default error handler is set to MPI::ERRORS_THROW_EXCEPTIONS, then on error the C++ exception mechanism
will be used to throw an MPI:Exception object.
Before the error value is returned, the current MPI error handler is called. By default, this error handler aborts the MPI job, except for
I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be
used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
