Hi All,
I had an issue in executing bcp command to connect to Sybase from Unix script for uploading the data from file to table.
I have a file called vrs_temp.txt (with two columns):

Data::Entropy::RawSource::Local(3pm) User Contributed Perl Documentation Data::Entropy::RawSource::Local(3pm)NAME
Data::Entropy::RawSource::Local - read randomness from local device
SYNOPSIS
use Data::Entropy::RawSource::Local;
my $rawsrc = Data::Entropy::RawSource::Local->new;
$rawsrc->sysread($c, 1);
# and the rest of the I/O handle interface
DESCRIPTION
This class provides a constructor to open an I/O handle connected to a local source of random octets. This may be a strong entropy source,
depending on the OS, but not every OS has such a facility at all.
There are no actual objects blessed into this class. Only the constructor belongs to this class; it returns "IO::File" objects. For use
as a general entropy source, it is recommended to wrap the handle using "Data::Entropy::Source", which provides methods to extract entropy
in more convenient forms than mere octets.
On systems with a blocking /dev/random, such as Linux, the bits generated can be totally unbiased and uncorrelated. Such an entropy stream
is suitable for all uses, including security applications. However, the rate of entropy generation is limited, so applications requiring a
large amount of apparently-random data might prefer to fake it cryptographically (see Data::Entropy::RawSource::CryptCounter).
On systems where /dev/random does not block, the bits generated are necessarily correlated to some extent, but it should be
cryptographically difficult to detect the correlation. Such an entropy source is not suitable for all applications. Some other systems
lack /dev/random entirely. If satisfactory entropy cannot be generated locally, consider downloading it from a server (see
Data::Entropy::RawSource::RandomOrg and Data::Entropy::RawSource::RandomnumbersInfo).
CONSTRUCTOR
Data::Entropy::RawSource::Local->new([FILENAME])
Opens a file handle referring to the randomness device, or "die"s on error. The device opened is /dev/random by default, but this may
be overridden by giving a FILENAME argument.
The default device name may in the future be different on different OSes, if their equivalent devices are in different places.
METHODS
There are no actual objects blessed into this class. The constuctor returns "IO::File" objects. See IO::File for the interface. It is
recommended to use unbuffered reads (the "sysread" method) rather than buffered reads (the "getc" method et al), to avoid wasting entropy
that could be used by another process.
