Hi,
I need add leading zeroes to a field in a file based on the character count. The field can be of 1 character to 6 character length. I need to make the field 14bytes.
eg:
8351,20,1
8351,234,6
8351,2,0
8351,1234,2
8351,123456,1
8351,12345,2
This should become.

Hi Forum.
I tried searching the forum but couldn't find a solution for my question.
I have the following data and would like to have a sed syntax to remove the leading zeroes from the 2nd field only:

Hi,
I have some hundreds/thousands of files named logX.dat, where X can be any integer, and they are sequential, X ranges between 1 and any number:

I would like to rename them to

Hello,
I got a question. I have several csv files with lots of data in it and for the first column i have EAN codes.
The problem that i am facing is that some of these codes have the leading 0 removed so they are 12 or less chars while a EAN code is (always?) 13 chars.
For this i used a... (9 Replies)
The awk below executes and produces the current output. it skips the header in row 1 and prints $4,$5,$6 and then adds the header row back.
The problem is that it keeps the tailing tab and prints it in front of $1. I could add a pipe to remove the tab, but is there a better way to do it with on... (7 Replies)

bytes - Perl pragma to force byte semantics rather than character semantics
NOTICE
This pragma reflects early attempts to incorporate Unicode into perl and has since been superseded. It breaks encapsulation (i.e. it
exposes the innards of how the perl executable currently happens to store a string), and use of this module for anything other than
debugging purposes is strongly discouraged. If you feel that the functions here within might be useful for your application, this possibly
indicates a mismatch between your mental model of Perl Unicode and the current reality. In that case, you may wish to read some of the perl
Unicode documentation: perluniintro, perlunitut, perlunifaq and perlunicode.
SYNOPSIS
use bytes;
... chr(...); # or bytes::chr
... index(...); # or bytes::index
... length(...); # or bytes::length
... ord(...); # or bytes::ord
... rindex(...); # or bytes::rindex
... substr(...); # or bytes::substr
no bytes;
DESCRIPTION
The "use bytes" pragma disables character semantics for the rest of the lexical scope in which it appears. "no bytes" can be used to
reverse the effect of "use bytes" within the current lexical scope.
Perl normally assumes character semantics in the presence of character data (i.e. data that has come from a source that has been marked as
being of a particular character encoding). When "use bytes" is in effect, the encoding is temporarily ignored, and each string is treated
as a series of bytes.
As an example, when Perl sees "$x = chr(400)", it encodes the character in UTF-8 and stores it in $x. Then it is marked as character data,
so, for instance, "length $x" returns 1. However, in the scope of the "bytes" pragma, $x is treated as a series of bytes - the bytes that
make up the UTF8 encoding - and "length $x" returns 2:
$x = chr(400);
print "Length is ", length $x, "
"; # "Length is 1"
printf "Contents are %vd
", $x; # "Contents are 400"
{
use bytes; # or "require bytes; bytes::length()"
print "Length is ", length $x, "
"; # "Length is 2"
printf "Contents are %vd
", $x; # "Contents are 198.144"
}
chr(), ord(), substr(), index() and rindex() behave similarly.
For more on the implications and differences between character semantics and byte semantics, see perluniintro and perlunicode.
LIMITATIONS
bytes::substr() does not work as an lvalue().
