thank you all for your replies but am still facing some issues
1. am trying to write it within code itself so for some reason whenever I use the single line bit of code from ahmad.diab and anchal_khare I get Bad name after lanF' I think am typing it in wrong.

2. The awk portion from you dennis jacob gives me just 4 digits and not 5. I get 4340 instead of 44340
Also for some reason the perl portion of reading in the file, at least doesnt give me any errors but am stuck at printing the value, how do I assign it to a variable

Apologies all, you have been very helpful but am a real novice here.

Any other suggestions will be very appreciated.
Thanks

err_get_reason

ERR_GET_LIB(3)							      OpenSSL							    ERR_GET_LIB(3)

NAME

       ERR_GET_LIB, ERR_GET_FUNC, ERR_GET_REASON - get library, function and reason code

SYNOPSIS

	#include <openssl/err.h>

	int ERR_GET_LIB(unsigned long e);

	int ERR_GET_FUNC(unsigned long e);

	int ERR_GET_REASON(unsigned long e);

DESCRIPTION

       The error code returned by ERR_get_error() consists of a library number, function code and reason code. ERR_GET_LIB(), ERR_GET_FUNC() and
       ERR_GET_REASON() can be used to extract these.

       The library number and function code describe where the error occurred, the reason code is the information about what went wrong.

       Each sub-library of OpenSSL has a unique library number; function and reason codes are unique within each sub-library.  Note that different
       libraries may use the same value to signal different functions and reasons.

       ERR_R_... reason codes such as ERR_R_MALLOC_FAILURE are globally unique. However, when checking for sub-library specific reason codes, be
       sure to also compare the library number.

       ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are macros.

RETURN VALUES

       The library number, function code and reason code respectively.

SEE ALSO

       err(3), ERR_get_error(3)

HISTORY

       ERR_GET_LIB(), ERR_GET_FUNC() and ERR_GET_REASON() are available in all versions of SSLeay and OpenSSL.

0.9.7a								    2000-01-31							    ERR_GET_LIB(3)
