It's been a while I know, but as I said I was busy learning bash
Not saying I got it all, I still got a long way to go...
I just wanted to post here what I've been able to do all on my own until now.
It will definitely seem barbaric to you and less elegant that what you did earlier with the awk command but as I'm not sure how to control it, I'm taking another road :
The great thing is that I can run it on any Linux machine plus I'm getting into each listing with this script to get info from there...
Now I've got to learn more about sed and grep to extract the information I need automatically and I'll be done .
Easy right? hopefully I will be able to do it soon.
If you have any comment on the script please be my guest! still trying to learn!
All the best!

In (german) medicine there is a proverb: who heals is right. In programming the same is true: as long as a program is doing what it is supposed to do it is kinda hard to argue ... ;-)
A few suggestions, though:
There is a difference between an unset variable and one that has a value of "" (empty string) or zero (for numbers). What you want is to declare the variable, so you can give some (meaningful) value to it, which is - if this yet to be determined - an empty value. In bash the keyword to declare variables is "local" or "declare" (or even "typeset", perhaps in an effort to be compatible to the Korn shell).
see above. As a suggestion: always give variables meaningful names. Once your script grows to some length and you juggle around several indexes at the same time you might want to have one i.e. "fooidx" and one "baridx" instead of "i" and "j".
You don't want to unset (that is: the opposite of define) the variable, just clear its content. So, like in the declaration, you just assign an empty string instead of unsetting it.
As a suggestion: i put commentary always at the same line as the line which it belongs to and always at a fixed horizontal position. Hence, instead of your loop, I'd write:
For my eyes this is easier to read, but again: whatever helps you you should do. In the pipeline:
You can do all in sed without an additional egrep:
As a rule of thumb: grep/sed/awk | grep/sed/awk is always wrong because it can be done in the respective tool chosen.
I hope this helps and have (more) fun programming.
For the first step you get the listing:
The second one you created a variable IDS that looks for the price, condition and date_updated and print the results.
I added a >> "/Users/myuser/Desktop/test.csv" to get the print exported to a CSV file.
I've been looking around for the past hour now and I can't seem to find how I can put each listing in a line with a ";" dividing the "description" (or "title") and the price, condition and date_updated instead of having 4 lines create per entry.
I know that something has to change between the "||" after the match and before the print, but I have no idea where and how...
Could you help me once more?
If you'd accept a trailing comma (removal would need additional measures), set the output record separator to comma: ORS=",". As ALL info would come in a long line, then, we need to find out how to separate a single machine's data from the next. I used the begin of a HTML doc for this. Try adding the following to your script
Please be aware that any comma INSIDE fields will lead to misinterpretation if the result is read somewhere else based on comma separated fields.
Gents,
Is there the possibility to improve this script to be able to have same output information.
I did this script, but I believe there is a very short code to get same output
here my script
awk -F, '{if($10>0 && $10<=15) print $6}' tmp1 | sort -k1n | awk '{a++} END { for (n in a )... (23 Replies)

I just wrote a very small script that improves readability on system sulog. The problem with all sulog is there is lack of clarity whether the info you are looking at is the most current.

Hi ,
i'm searching for files over many Aix servers with rsh command using this request :

and then count them with "wc"

Hi all,
Still a newbie and learning as I go ... as you do :)
Have created this script to report on disc usage and I've just included the ChkSpace function this morning.
It's the first time I've read a file (line-by-bloody-line) and would like to know if I can improve this script ?
