Hello Unix experts,

If I could get any explanations on why the code below doesn't work it would be great !

My input looks like that ("|" delimited):
Saaaaabbbbbccccc|ok
Sdddddfffffggggg|ok
...

So you mean I should
1st) sort by field1 and generate a first output
2nd) use this output to sort by subfield 2 and generate the final output.

I tried things like below but still doesn't work....

input ("/" delimited fields):
style1/book1 (author_C)/editor1/2000
style1/book2 (author_A)/editor2/2004
style1/book3 (author_B)/editor3/2001
style2/book8 (author_B)/editor4/2010
style2/book5...

It depends. I would need to put the task I described in my first post into a function as it is a recurrent task in the script.
So my question is: can you write a part of a function in the END...

alister: this task will be part of a function as I have to repeat it multiple times. Can a function refer to rules written in an END block?

Rudic: Thanks for your help. I understand the approach...

It is part of a bigger script with several redirections, just to keep it simple

input:
ref001, Europe, Belgium, 1001
ref001, Europe, Spain, 203
ref001, Europe, Germany, 457
ref002, America, Canada, 234
ref002, America, US, 87
ref002, America, Alaska, 652

Without using...

Thanks Don Cragun and spacebar !

But is it possible without using an END section?

And without using an END section, is it doable...:)

Using awk, is there a way to remove newlines in strings that don't contain 1_ at the beginning, but without setting RS="1_" in the BEGIN section and without using a END section as well?

input:...

Ok, I was wondering if there was a built-in variable like FILENAME but for the other way
:wall:

Thanks anyway !

Hi all!

Is it possible with awk to redirect all the records of a file that match a string in a field to a specific file.

input.tab:
aaaaa|bbbbbb|KKKKK
cccccc|dddddd|SSSSS...

Ok I get it !

So, if I understood well, if I am sure that my input will contain only one character per field, with the same number of columns for every line, I can use this code instead:
...

Thanks elixir !

However, i don't understand the point of
if(NF>max) max=NF

Why not just use i<=NF directly in the END section ?

AND

start=match(a[i],$i)
if(start &&...

It leaves the first ",":

blue|,red,green

Hi rangarasan !

Your code returns:

b
blue|red,red,green,red

Without the ";", it suppresses the first "b" but only list the second column:

blue|red,red,green,red

That's the role of
...

Thanks elixir_sinari !

Can you tell me what a[$1] stands for ?

Does it mean "the first column"?

Hi all !

If there is only one single value in a column (e.g. column 1 below), then return this value in the same output column.
If there are several values in the same column (e.g. column 2...

Great !

Thanks!

but what is the function of the "return" statement?

Ok, but How do you call the function?

I tried with:
{b = split($2,a,", ")
for (i=1; i<=b; i++){
n = a[i]

convert($2)

}
}1

{b =...

Hi Peasant !

Thanks for your advices.

However when I use only the codes of the function it prints the original line in record 1, and then the wanted line in record2 !!!!

And when I use the...

Hi Scrutinizer !



So I tried:
#!/usr/bin/gawk -f

BEGIN{FS=OFS="|"}

n = split($2,a,", ")
for (i=1; i<=n; i++){

if (a[i] < 3999) {

Hi balajesuri !

ok, I see

Hi !

I got a script from [Arabic to Roman numeral conversion - .comp.lang.awk (http://www.freag.net/en/t/1k9s2/arabic_to_roman), that I would like to modify to apply it on my input file.
