I doesn't work GhostDog, well it probably does, but not in my case.
I did something like that:

Code:

NR==FNR {a[$2]=$1;next} #I read a first file to get the search pattern
{if ($3 in a)
    {$3=a[$3]
    print
    d=9
    next}
    d--&&d>=0
}

But it does only print the first line.

Here is an example of my files.
The first file where I read the values looks like this:

Code:

a1 b1
a2 b2
a3 b3

Then the second file looks like: (there is also other stuff in the file not related)

Code:

....
/begin MEASUREMENT b1
   "comment" 
   UWORD 
   ident 
   1 
   100
   0 
   65535 
   ECU_ADDRESS 0x4000582C
  /end MEASUREMENT 
....

I want to check if $3==b1, then replace it with a1 and copy the others lines at the end of the file, and do it for each bi of the first file.

thanks for your help.

Found a solution doing this:

Code:

NR==FNR {a[$2]=$1;next}
{if ($3 in a)
    {$3=a[$3]
    print
    d=9
    while (d>0)
    {getline; print; d--}
    }
}
