Actually I got a list of file end with *.txt
I want to use the same command apply to all the *.txt
Thus I try to find out the fastest way to write those same command in a script and then want to let them run automatics.
For example:
I got the file below:
file1.txt
file2.txt
file3.txt... (4 Replies)
Hi Experts,
I am adding a column of numbers with awk , however not getting correct output:
# awk '{sum+=$1} END {print sum}' datafile
2.15291e+06
How can I getthe output like : 2152910
Thank you..
# awk '{sum+=$1} END {print sum}' datafile

Hi,
I have a situation to compare one file, say file1.txt with a set of files in directory.The directory contains more than 100 files.
To be more precise, the requirement is to compare the first field of file1.txt with the first field in all the files in the directory.The files in the... (10 Replies)
Hello experts,
I'm stuck with this script for three days now. Here's what i need.
I need to split a large delimited (,) file into 2 files based on the value present in the last field.
Samp: Something.csv

bca,adc,asdf,123,13C

crypt::rijndael
Rijndael(3pm) User Contributed Perl Documentation Rijndael(3pm)NAME
Crypt::Rijndael - Crypt::CBC compliant Rijndael encryption module
SYNOPSIS
use Crypt::Rijndael;
# keysize() is 32, but 24 and 16 are also possible
# blocksize() is 16
$cipher = Crypt::Rijndael->new( "a" x 32, Crypt::Rijndael::MODE_CBC() );
$cipher->set_iv($iv);
$crypted = $cipher->encrypt($plaintext);
# - OR -
$plaintext = $cipher->decrypt($crypted);
DESCRIPTION
This module implements the Rijndael cipher, which has just been selected as the Advanced Encryption Standard.
keysize
Returns the keysize, which is 32 (bytes). The Rijndael cipher actually supports keylengths of 16, 24 or 32 bytes, but there is no way
to communicate this to "Crypt::CBC".
blocksize
The blocksize for Rijndael is 16 bytes (128 bits), although the algorithm actually supports any blocksize that is any multiple of our
bytes. 128 bits, is however, the AES-specified block size, so this is all we support.
$cipher = Crypt::Rijndael->new( $key [, $mode] )
Create a new "Crypt::Rijndael" cipher object with the given key (which must be 128, 192 or 256 bits long). The additional $mode
argument is the encryption mode, either "MODE_ECB" (electronic codebook mode, the default), "MODE_CBC" (cipher block chaining, the same
that "Crypt::CBC" does), "MODE_CFB" (128-bit cipher feedback), "MODE_OFB" (128-bit output feedback), or "MODE_CTR" (counter mode).
ECB mode is very insecure (read a book on cryptography if you dont know why!), so you should probably use CBC mode.
$cipher->set_iv($iv)
This allows you to change the initial value vector used by the chaining modes. It is not relevant for ECB mode.
$cipher->encrypt($data)
Encrypt data. The size of $data must be a multiple of "blocksize" (16 bytes), otherwise this function will croak. Apart from that, it
can be of (almost) any length.
$cipher->decrypt($data)
Decrypts $data.
Encryption modes
Use these constants to select the cipher type:
MODE_CBC - Cipher Block Chaining
MODE_CFB - Cipher feedback
MODE_CTR - Counter mode
MODE_ECB - Electronic cookbook mode
MODE_OFB - Output feedback
MODE_PCBC - ignore this one for now :)

BUGS
Should EXPORT or EXPORT_OK the MODE constants.
