Hi, patrick87:
Code:
awk 'FNR==NR {if (/^>/) p=substr($0,2); else a[p]=a[p] $0; next} {printf(">%s_0.%02u\n%s\n", $1, ++i[$1], substr(a[$1], $2, $3-$2+1))}' f1 f2

While processing the first file (FNR==NR), if a line begins with ">", grab everything that follows it and store it in p, the pattern name. If a line does not begin with a ">", then it is data for the current pattern, p; append the line to a[p], that pattern's entry in array a. Repeat until done with the first file.

For the second file, we use the pattern name in the first field and the index values in the second and third fields to extract the required substring from a[$1], while incrementing a counter for each pattern name seen, in the i array, i[$1].

Cheers,
Alister
