hi all
can anyone please let me know if there is a way to find out duplicate rows in a file. i have a file that has hundreds of numbers(all in next row).
i want to find out the numbers that are repeted in the file.
eg.
123434
534
5575
4746767
347624
5575
i want 5575
please help (3 Replies)
I have searched the internet for duplicate row extracting.
All I have seen is extracting good rows or eliminating duplicate rows.
How do I extract duplicate rows from a flat file in unix.
I'm using Korn shell on HP Unix.
For.eg.
FlatFile.txt

Hi all,
I have written one shell script. The output file of this script is having sql output.
In that file, I want to extract the rows which are having multiple entries(duplicate rows).
For example, the output file will be like the following way.

I would appreciate if anyone can help. Thanks. (4 Replies)
Hi ,
I have a data file in this format.
p1 p2 p3
10 0
10 0 1000
I am using a sqlloader script to load the data into the database table.There is a unique constraint on the columns p1 and p2.
So, sqlldr cannot load both the records. This eliminates duplicate records from being... (1 Reply)
I feel stupid for asking this because it seems that MYSQL code isn't working the way that I think it should work.
Basically I wrote code like this:
select * from `Test_DC_Trailer` HAVING max(DR_RefKey);
Where the DR_RefKey is a unique numeric field that is auto iterated (like a primary key)... (7 Replies)

rc4
rc4(3SSL) OpenSSL rc4(3SSL)NAME
RC4_set_key, RC4 - RC4 encryption
SYNOPSIS
#include <openssl/rc4.h>
void RC4_set_key(RC4_KEY *key, int len, const unsigned char *data);
void RC4(RC4_KEY *key, unsigned long len, const unsigned char *indata,
unsigned char *outdata);
DESCRIPTION
This library implements the Alleged RC4 cipher, which is described for example in Applied Cryptography. It is believed to be compatible
with RC4[TM], a proprietary cipher of RSA Security Inc.
RC4 is a stream cipher with variable key length. Typically, 128 bit (16 byte) keys are used for strong encryption, but shorter insecure
key sizes have been widely used due to export restrictions.
RC4 consists of a key setup phase and the actual encryption or decryption phase.
RC4_set_key() sets up the RC4_KEY key using the len bytes long key at data.
RC4() encrypts or decrypts the len bytes of data at indata using key and places the result at outdata. Repeated RC4() calls with the same
key yield a continuous key stream.
Since RC4 is a stream cipher (the input is XORed with a pseudo-random key stream to produce the output), decryption uses the same function
calls as encryption.
Applications should use the higher level functions EVP_EncryptInit(3) etc. instead of calling the RC4 functions directly.
RETURN VALUES
RC4_set_key() and RC4() do not return values.
NOTE
Certain conditions have to be observed to securely use stream ciphers. It is not permissible to perform multiple encryptions using the
same key stream.

RC4_set_key() and RC4() are available in all versions of SSLeay and OpenSSL.
