Store values in an Array
Hi all.

Well, I have the next code:

Quote:
awk -F: '{
for(i=1; i<=NF; i++)
{
#b[i]="$" i
#b[i]="caca"
}
}' tmpid
I need to make an array with the values I have in the bucle, but just don't get it...

Question is, how can I store in an array that values, and how can I display them with echo?

Code:
awk -F: '{
for(i=1; i<=NF; i++)
   b[i]=$i
}' tmpid

OR
Code:
awk -F: '{
  split($0, b, FS)
}' tmpid

vgersh99,

I tried that before, but when I write echo ${b[1]} then I get a blank.

Why this happen?

Franklin52,

I'll be more careful from now on. Sorry.

'echo' is a shell command. 'b' is your awk array.
Code:
awk -F: '{
for(i=1; i<=NF; i++) 
   b[i]=$i

for(j=1; j<=i; j++)
   printf("j->[%d] b[%d]->[%s]\n", j, j, b[j])
}' tmpid

vgersh99,

Im new in the unix world. So now I understand what you told me before.

So, the variables I set within awk, can't be used in shell later?

I mean, I created an array named "b" with "x" elements. That variable is exclusive within awk, isn't it?
