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.

pnmsplit
pnmsplit(1) General Commands Manual pnmsplit(1)NAME
pnmsplit - split a multi-image portable anymap into multiple single-image files
SYNOPSIS
pnmsplit [pnmfile[ output_file_pattern]]
DESCRIPTION
Reads a Netpbm file as input. Copies each image in the input into a separate file, in the same format.
pnmfile is the file specification of the input file, or - to indicate Standard Input. The default is Standard Input.
output_file_pattern tells how to name the output files. It is the file specification of the output file, except that the first occurence
of "%d" in it is replaced by the image sequence number in unpadded ASCII decimal, with the sequence starting at 0. If there is no "%d" in
the pattern, pnmsplit fails.
The default output file pattern is "image%d".
Note that to do the reverse operation (combining multiple single-image PNM files into a multi-image one), there is no special Netpbm pro-
gram. Just use cat.
