Can someone please help me with this SHELL script?
I need to create a script that gets a positive number n as an argument. The script must calculate the factorial of its argument. In other words, it must calculate n!=1x2x3x...xn. Note that 0!=1.
Here is a start but I have no clue how to... (3 Replies)

Hi all,
While doing some checks I found a kind of interesting arithmetic factorial chart with sed, sharing this may be simple but thought to share,
# n=20;for i in `seq $n`;do printf "`seq $i|xargs|sed 's/ /*/g'`= ";echo "`seq $i|xargs|sed 's/ /*/g'`"| bc;done
1= 1

mpi_recv_init
MPI_Recv_init(3OpenMPI)MPI_Recv_init(3OpenMPI)NAME
MPI_Recv_init - Builds a handle for a receive.
SYNTAX C Syntax
#include <mpi.h>
int MPI_Recv_init(void *buf, int count, MPI_Datatype datatype,
int source, int tag, MPI_Comm comm, MPI_Request *request)
Fortran Syntax
INCLUDE 'mpif.h'
MPI_RECV_INIT(BUF, COUNT, DATATYPE, SOURCE, TAG, COMM, REQUEST,
IERROR)
<type> BUF(*)
INTEGER COUNT, DATATYPE, SOURCE, TAG, COMM, REQUEST, IERROR
C++ Syntax
#include <mpi.h>
Prequest Comm::Recv_init(void* buf, int count, const
Datatype& datatype, int source, int tag) const
INPUT PARAMETERS
count Maximum number of elements to receive (integer).
datatype Type of each entry (handle).
source Rank of source (integer).
tag Message tag (integer).
comm Communicator (handle).
INPUT /OUTPUT PARAMETER
buf Initial address of receive buffer (choice).
OUTPUT PARAMETERS
request Communication request (handle).
IERROR Fortran only: Error status (integer).
DESCRIPTION
Creates a persistent communication request for a receive operation. The argument buf is marked as OUT because the user gives permission to
write on the receive buffer by passing the argument to MPI_Recv_init.
A persistent communication request is inactive after it is created -- no active communication is attached to the request.
A communication (send or receive) that uses a persistent request is initiated by the function MPI_Start or MPI_Startall.
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.
