A find and replace script
Hello everyone,
I am trying to do a simple script (shell or perl) for a bioinformatic problem, where I want to use a list from file2 and append this information to file1 (output).

Example:
File1
Code:
>Apple1 
GAGACGATTTATATATAGAAGAGAG
>Banana2 
CAGAGAGAGAGACCCCCCCCCCCC

File2
Code:
>Apple1      20     100
>Banana2    30     300

Ouput (new File1)
Code:
>Apple1   20     100
GAGACGATTTATATATAGAAGAGAG
>Banana2  30     300
CAGAGAGAGAGACCCCCCCCCCCC


If anyone has any feedback that would be greatly appreciated.


Cheers
