I am trying to figure out a way to combine multiple sources with different data on a single file, and I am trying to find the best way to do it.
I have multiple files, let's say A, B, C and D. A has a field in common with B, B has a field in common with C, and C has a field in common with D.
I want the output file to have all records from file A, and to pull the fields from the other sources, for example
Code:
file A
2
3
file B (field 1 is common to A field 1)
1 10
2 20
3 30
4 40
file C (field 1 is common to B field 2)
10 abc
20 def
30 ghi
40 jkl
file D (field 1 is common to C field 2)
abc Cat
def Bird
ghi Dog
xyz Fish
The desired output file would contain
Code:
2 20 def Bird
3 30 ghi Dog
As I am new to this, I was first thing about running a mix of nested while read's and greps and echoing the output to a file. Is there any cleaner way to do this? Each file can be really big, and I think nesting while read's can make it slow.

lookbib - find references in a bibliographic database
SYNOPSIS
lookbib database
DESCRIPTION
A bibliographic reference is a set of lines, constituting fields of bibliographic information. Each field starts on a line beginning with
a `%', followed by a key-letter, then a blank, and finally the contents of the field, which may continue until the next line starting with
`%'.
The lookbib utility uses an inverted index made by indxbib to find sets of bibliographic references. It reads keywords typed after the `>'
prompt on the terminal, and retrieves records containing all these keywords. If nothing matches, nothing is returned except another `>'
prompt.
It is possible to search multiple databases, as long as they have a common index made by indxbib(1). In that case, only the first argument
given to indxbib is specified to lookbib.
If lookbib does not find the index files (the .i[abc] files), it looks for a reference file with the same name as the argument, without the
suffixes. It creates a file with a .ig suffix, suitable for use with fgrep (see grep(1)). lookbib then uses this fgrep file to find refer-
ences. This method is simpler to use, but the .ig file is slower to use than the .i[abc] files, and does not allow the use of multiple
reference files.
FILES

x.ib
x.ic index files
