[SOLVED] Editing a file using awk

riteshanand40 · 04-29-2010, 06:40 AM

Hi,

I have a list of millions of filename in form of say "drau3DDFEA5E01205841DC1B277A".
I need it convert it into
usr/local/data/d/dr/dra/drau/drau3DDFEA5E01205841DC1B277A

I believe that can be achieved by awk or sed.
I am very new to these. Can someone help plz.

Regards,
Ritesh

No need for awk here. The shell manages substring extraction easily:

Code:

#!/bin/bash
filename=drau3DDFEA5E01205841DC1B277A
for i in {1..4}
do
  filepath=$filepath/${filename:0:$i}
done
filepath=usr/local/data$filepath/$filename
