Hi praveenraj.1991,
Yoda's script may work fine for you, but your requirements are a little vague.
Can 0 be a key? If so, can 00 be a key? If so, are 0 and 00 distinct keys? (If the answer to any of these is yes, Yoda's script won't work for you.)
If you have lines:
what should be the output? Or, more explicitly, does the order matter: are 11|55 and 55|11 duplicates keys? And, does each pair of keys have to be unique, or does each individual key have to be unique: are 55|11 and 11|30 duplicates because 11 is a common key? (If the answer to any of these is yes, Yoda's script won't work for you.)
I have a huge file (over 30mb) that I am processing through with perl. I am pulling out a list of filenames and placing it in an array called @reports.
I am fine up till here. What I then want to do is go through the array and find any duplicates. If there is a duplicate, output it to the screen.... (3 Replies)

Hi,
can I do something like this to add a condition of checking if the 4th field is number or space or blank also:
awk -F, '$4 /^*||*/' MYFILE >> OTHERFILE
I also want the other part i.e. I need to exclude all lines whose 4th field is space or blank or number:
MYFILE

Hi,
I have a pipe seperated file
I want to write a code to display count of lines that have 20th field not null.
nawk -F"|" '{if ($20!="") print NR,$20}' xyz..txt
This displays records with 20th field also null.
I would like output as: (4 Replies)
I was trying to use the AIX 6.1 sort command to sort fixed-length data records, sorting by specific columns only. It took some time to figure out how to get it to work, so I wanted to share the solution. The sort man page wasn't much help, because it talks about field delimeters (default space... (1 Reply)
I am currently creating a script to find filenames that are listed once in an input file (find non duplicates). I then want to report those single files in another file. Here is the function that I have so far:

Hi team,
I have 20 columns csv files. i want to find the duplicates in that file based on the column1 column10 column4 column6 coulnn8 coulunm2 . if those columns have same values . then it should be a duplicate record.
can one help me on finding the duplicates,
Thanks in advance.

rsa_check_key
RSA_check_key(3) OpenSSL RSA_check_key(3)NAME
RSA_check_key - validate private RSA keys
SYNOPSIS
#include <openssl/rsa.h>
int RSA_check_key(RSA *rsa);
DESCRIPTION
This function validates RSA keys. It checks that p and q are in fact prime, and that n = p*q.
It also checks that d*e = 1 mod (p-1*q-1), and that dmp1, dmq1 and iqmp are set correctly or are NULL.
As such, this function can not be used with any arbitrary RSA key object, even if it is otherwise fit for regular RSA operation. See NOTES
for more information.
RETURN VALUE
RSA_check_key() returns 1 if rsa is a valid RSA key, and 0 otherwise. -1 is returned if an error occurs while checking the key.
If the key is invalid or an error occurred, the reason code can be obtained using ERR_get_error(3).
NOTES
This function does not work on RSA public keys that have only the modulus and public exponent elements populated. It performs integrity
checks on all the RSA key material, so the RSA key structure must contain all the private key data too.
Unlike most other RSA functions, this function does not work transparently with any underlying ENGINE implementation because it uses the
key data in the RSA structure directly. An ENGINE implementation can override the way key data is stored and handled, and can even provide
support for HSM keys - in which case the RSA structure may contain no key data at all! If the ENGINE in question is only being used for
acceleration or analysis purposes, then in all likelihood the RSA key data is complete and untouched, but this can't be assumed in the
general case.
BUGS
A method of verifying the RSA key using opaque RSA API functions might need to be considered. Right now RSA_check_key() simply uses the RSA
structure elements directly, bypassing the RSA_METHOD table altogether (and completely violating encapsulation and object-orientation in
the process). The best fix will probably be to introduce a "check_key()" handler to the RSA_METHOD function table so that alternative
implementations can also provide their own verifiers.
