Thank to the both of you. I will attempt to give it a shot. Likely I'll be back.

Corona,
What if I wanted to keep $1 as it is in the code and have an x amount of spaces or a tab between each delimiter, how would that look and where would that statement start?
Hi,
I am trying to do the following using AWK program.
1. Read the input data file
2. Parse the record and see if it contains errors
3. If the record contains errors, then write it into Reject file, else, write into usual output file or display it on the screen
Here is what I have done -... (6 Replies)
Well, it didn't take me long to get stumped again. I assure you that I'm not mentally deficient, just new to scripting.
So, here's the gist. I want to redirect output from awk based off of which branch of an if-else statement under which it falls.

Hi All,
Looking for a quick AWK script to output some differences between two files.

device1 2.2.2.2 PINGS
FILE2

Hi guys,
Basically, I have an END {print NR} statement in my awk script to count the number of records as I have concatenated multiple files. But instead of generating this total number of records to the same output data file. I want to put this in a separate control file using the same awk... (6 Replies)

I am trying to do the following using awk (is that the best way?):
Read 2 files created from the output of df (say, on different days) and compare the entries using the 1st (FileSys) and 6th (Mount) fields to see if the size has changed. Output (at least), to a new file (some header... (2 Replies)
It seems like a common task, but I haven't been able to find the solution.

I am using awk to read lines from a CSV file then put data into other files. These other files are named using the value of a certain column. Column 7 is a name such as "att" or "charter" . I want to end up with file names with the value of column 7 appended to them, like this:

I have two large files (~250GB) that I am trying to remove the where GT: 0/0 or 1/1 or 2/2 for both files. I was going to use a bash with the below awk, which I think will find each line but how do I remove that line is that condition is found? Thank you :).

I am trying to output the matches between $1 of file1 to $3 of file2 into a new file match.
I am also wanting to output the mismatches between those same 2 files and fields to two separate new files called missing from file1 and missing from file2. The input files are tab-delimited, but the... (9 Replies)
The awk below when run using the contents of file, works great with the desired output of

However, when the complete file is used (attached) I get different output. It looks like the same data is there but the ordering is off. Both data sets are... (2 Replies)

bytes(3pm) Perl Programmers Reference Guide bytes(3pm)NAME
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().
