Worked like charm. Sorry for the newbie post, I promise I learn more before next time. :)

Hello,

I'm completely new to Perl and I'm just looking for a quick answer to some code I'm trying to come up with. I'm trying to access a website, part of the URL I want the user to be able to...

NVL isn't supported with psql according to what I've read, but your example keyed me in on how to use coalesce. This did the trick.


SELECT name,date,coalesce(value,0) FROM table;


Regards,...

Well as the title describes, its a pretty straight forward problem. I have a series of psql tables where there are lots of blanks. However there is at least one column, called name, that will never...

Give the code:


set line = 2
set year = `sed -n '2p' file

while ($line < 500)

echo $line > f.txt

@ line = $line + 1
end



How do I utilize the variable $line in the code instead...

I have not used two dimensional arrays before. I will look into it. thanks,

I think your right. I've search through all sorts of online documentation, and have found nothing. No big deal. Time to find a better route. :)

This is a re-post of a previous topic. However I'm simplifying it to hopefully get a response this time.

Given the following variables:


$id = "home";
$home=array("4.8","2.3");


I want to...

Okay, probably an easy solution, but I've given up. I want to set a variable with a variable and print it in PHP. I just can't get the syntax right. As an example:


$place["t"] = "T";
...

okay that post was not helpful in the least. I understand not to include perl in the string, I meant to take it out. any other help out there?

Alright,

I'm new to Perl so be gentle. Given the following script:
----
open(file, "<file.txt");

@lines = <file>;
close(file);

$var = print $lines[18];
----

So I'm printing line 18...

I'm new to PERL, but I want to take the page source and write it to a file or standard output. I used perl.org as a test website. Here is the script:

use strict;
use warnings;

well I need to grep using the string I supplied in the initial post. I'm searching for a string called pd with a space after it. So I need to grep "/pd ". Parentheses alone don't work.

How can I use grep to grab a line that contains a forward slash? I've tried:

grep "/pd " file,

Inevitably it just grabs pd not /pd.

Looks like I was just over thinking the issue. Thanks. ;)

okay, this shouldn't be difficult but I can't figure it out. How can I set a variable with another variable. I have the following:

foreach pe ($dir $sp)

set tpe = `echo $pe | grep M`
if ($tpe...

thanks for the help, don't worry it isn't homework.

Yeah I didn't phrase my question the way I wanted to. Let me try again.

Given the following:
----------------------
foreach var (t v w)

grep $var ./file > ./newfile

set ${var}temp = `awk...

It doesn't matter. Personal preference i guess. To me the awk command is a bit complicated. It's not something you could easily come up with, unless you know it. Whereas the tr command is a bit...

tr is like awk, sed, any other unix command. tr indicates you want to begin "translating" something to follow. What you want to translate, followed by what you want it to become, then the filename,...

tr means translate. It's a cool function, you can translate most things from one character to another. It works like sed more or less, just one more tool to have in your unix bag of tricks.

i would do this instead. translate the / to a space. then awk the 5th field.


tr "/" " " ./file | awk '{print $5}'

I have the following
--------------------
foreach var (STO SNY WKF)

set ta = 5

end

How can I echo both variables at the same time. Something to the effect of

I have a script that has a counter in it, the output from the script puts the values in columns, and when the values are greater than 9 it moves the rest of the row over, hence displacing the...

I need to assign a variable within a variable in a sed command.
I tried doing the following in c shell.


set left = 1
set right = 2
set segment = qwerty
