Your desired output from post#1 is matched neither by your own code snippet's result nor by Chubler_XL's. To introduce file1's second column as column 2 in the output, try
(Chubler_XL's code adapted)
To your last question: If in file1 there's exact duplicates, nothing will happen except that a[$1] will be overwritten with the identical value. If the values are not identical, the last one will apply.
Hi,
I'm trying to find the nearest match between two columns of numbers, e.g.
1,1
10,8
30,50
20,100
and the search could be e.g. 20,20
returning 10,8 - i.e. 20-10 = 10 and 20-8 = 12 totalling 22, and hence being the nearest match.
any ideas?
thanks a lot, (1 Reply)

zdiff
ZDIFF(1) General Commands Manual ZDIFF(1)NAME
zcmp, zdiff - compare compressed files
SYNOPSIS
zcmp [ cmp_options ] file1 [ file2 ]
zdiff [ diff_options ] file1 [ file2 ]
DESCRIPTION
Zcmp and zdiff are used to invoke the cmp or the diff program on files compressed via gzip. All options specified are passed directly to
cmp or diff. If only file1 is specified, it is compared to the uncompressed contents of file1.gz. If two files are specified, their con-
tents (uncompressed if necessary) are fed to cmp or diff. The input files are not modified. The exit status from cmp or diff is pre-
served.
SEE ALSO cmp(1), diff(1), zmore(1), zgrep(1), znew(1), zforce(1), gzip(1), gzexe(1)BUGS
Messages from the cmp or diff programs may refer to file names such as "-" instead of to the file names specified.
