Shell Programming and Scripting

Hi all,

I have 2 files, One file contain data like this

Code:

FHIT 
CS 
CHRM1 
PDE3A 
PDE3B 
HSP90AA1 
PTK2 
HTR1A 
ESR1 
PARP1 
PLA2G1B

These names are mentioned in the second file(Please see attached second file) as

# Drug_Target_X_Gene_NameWhere X can be any number (1-1000)

Now the second file contain data like this where these entries (Drug_Target_X_Gene_Name) are present

#BEGIN_DRUGCARD DB0xxxx (0001- 8820)

# Drug_Target_X_Gene_Name

Description

#END_DRUGCARD DB0xxxx (0001- 8820)



So, if any entry of first file matches with second file

Drug_Target_X_Gene_Name

I want to fetch following entry in a separate file

# Description:

So, if the CHRM1 from first file is present in Drug Card 00001 of second file as # Drug_Target_X_Gene_Name
the output shuld be

Code:

CHRM1       (Description in front like thid for eg: Lepirudin is identical to        natural hirudin except for substitution of  .....)

It is also possible CHRM1 is present in more than one drug cards, in that case there will be two different descriptions from two different drug cards

Code:

CHRM1       (Description in front like this for eg: Lepirudin is identical to        natural hirudin except for substitution of  .....) 
CHRM1       (Description in front like this for eg: Dornase alfa is a biosynthetic form of human deoxyribunuclease I (DNase I) enzyme. It is produced in genetically modified    Chinese hamster ovary   .....)

In same way for all entries of first file I need description from drug cards of second file if these entries are present in any of the drug card of second file.

Any help will be really appreciated.
