Hello,
Can you explain why in the first 2 commands the awk does not print anything? Is it looking of a specific format ?
Thanks.
$ echo 12a3 | awk '($1>=2) {print $1}' # prints nothing
$ echo 123a | awk '($1>=2) {print $1}' # prints nothing
$ echo a123 | awk '($1>=2) {print $1}'

I do not know how to do this unless I use a bunch of if statements. I need a script to replace numbers in each record in a file. I am really getting tangled in this web.
If a fieldA (19 positions) is greater than 14 digits, I have to change the data (resulting fieldA is fixed 19 postions).

Hi Everyone,
# cat 1
1;2;3;4;5;6
1;2;3;4;5;
# awk -F ";" '$5 == "5"' 1
1;2;3;4;5;6
1;2;3;4;5;
but the output is should be just "1;2;3;4;5;6" means 1st condition: $5 is 5; 2nd condition: $6 is not empty, please advice. Thanks (2 Replies)
Hi there,
I wanna define a variable 'tempbase'. Therefore I read a text file "base.out". "base.out" contains a list with four columns. 'tempbase' is the 4th entry in the line, where the first entry is equal to the predefined variable $orb1 and the second entry is equal to $orb2. I wrote the code... (2 Replies)

I'm having a problem pulling UID's from data. The data outputs a user's UID in one of three ways:
1. Error User user_name already assigned with <UID>
2. Success <UID> reserved for user_name
3. <a load of crap because there was a db failure yet somehow the UID is still in there>

hello gurus,
I want to use an associative array from a file to populate a field of another file, by matching several columns in order of priority. If the first column matches, then i dont want to match $2. Similarly I only want to match $3 when $1 and $2 are not in associative array.

tm::resourceable
TM::ResourceAble(3pm) User Contributed Perl Documentation TM::ResourceAble(3pm)NAME
TM::ResourceAble - Topic Maps, abstract trait for resource-backed Topic Maps
SYNOPSIS
package MyNiftyMap;
use TM;
use base qw(TM);
use Class::Trait ('TM::ResourceAble');
1;
my $tm = new MyNiftyMap;
$tm->url ('http://nirvana/');
warn $tm->mtime;
# or at runtime even:
use TM;
Class::Trait->apply ('TM', qw(TM::ResourceAble));
my $tm = new TM;
warn $tm->mtime;
DESCRIPTION
This traits adds methods to provide the role resource to a map. That allows a map to be associated with a resource which is addressed by a
URL (actually a URI for that matter).
Predefined URIs
The following resources, actually their URIs are predefined:
"io:stdin"
Symbolizes the UNIX STDIN file descriptor. The resource is all text content coming from this file.
"io:stdout"
Symbolizes the UNIX STDOUT file descriptor.
"null:"
Symbolizes a resource which never delivers any content and which can consume any content silently (like "/dev/null" under UNIX).
Predefined URI Methods
"inline"
An inlined resource is a resource which contains all content as part of the URI. Currently the TM content is to be written in AsTMa=.
Example:
inlined:donald (duck)
INTERFACE
Methods
url $url = $tm->url
$tm->url ($url)
Once an object of this class is instantiated it keeps the URL of the resource to which it is associated. With this method you can
retrieve and set that. No special further action is taken otherwise.
mtime
$time = $tm->mtime
This function returns the UNIX time when the resource has been modified last. 0 is returned if the result cannot be determined. All
methods from LWP are supported.
Special resources are treated as follows:
"null:"
always has mtime 0
"io:stdin"
always has an mtime 1 second in the future. The idea is that STDIN always has new content.
"io:stdout"
always has mtime 0. The idea is that STDOUT never changes by itself.
