Top Forums UNIX for Dummies Questions & Answers Join 2 files with multiple columns: awk/grep/join? Post 302376581 by InfoSeeker on Tuesday 1st of December 2009 07:45:51 PM

Thank you both for your replies. Unfortunately I have tried both of them,

1. with the awk script I only ended up getting the headers as the output:
PDB CHAIN StartPos EndPos PDB CHAIN StartPos EndPos

2. With the join command I output to a txt file but I ended up with nothing?

Could you both kindly explain the code to me? Maybe if I get the logic then I can modify it accordingly. Thanks!

I doubled checked, I had wrongly-formatted files so the commands weren't working properly. Both working find now! Smilie
Thank you very much!!

PS: Is there a way however to modify it so that I don't end up with duplicates:
For example, I end up with
glelk 1avq A 129 133 1avq A 129 133
which is basically an identical row in both FilesA and FilesB

CHAIN(3)						 MBK UTILITY STRUCTURE DEFINITIONS						  CHAIN(3)

NAME
chain - mbk lisp-like service structure DESCRIPTION
The chain is used for any purpose, when a list of pointer is required. The use of this structure is strongly recommanded, when such a need occurs. The declarations needed to work on chain are available in the header file "/labo/include/mut315.h", where '315' is the actual mbk version. The following C structure supports the description of the chain : typedef struct chain { struct chain *NEXT; void *DATA; } chain_list; NEXT Pointer to the next chain of the list. DATA Generic pointer used to point to any kind of object. Do not forget to cast the pointer back to its previous type when using this field. Remark : a specialized memory allocator has been built in order to create and free chain_lists, so absolutly avoid to create or free them an other way than through the access functions. SEE ALSO
mbk(1), addchain(3), freechain(3), delchain(3). BUG REPORT
This tool is under development at the ASIM department of the LIP6 laboratory. We need your feedback to improve documentation and tools. ASIM
