Extracting combined differences based on a single column
Dear All,
I have two sets of files. File 1 can be any number between 1 and 20 followed by a frequency of that number in a give documents... the lines in the file will be dependent to the analysed document. e.g.
file1
Code:
1,5
4,1

then I have file two which is basicall same numbers but with frequency of 0
file2
Code:
1,0
2,0
3,0
4,0
...
20,0

I want to create a third file which will map the file1 on file2
file3 - outcome
Code:
1,5
2,0
3,0
4,1
...
20,0

I have tried
Code:
awk -F, 'FNR==NR{X[$1]=$2;next}$1 in X{print $1","X[$1]==$2;next}{print $1","0}' file1 file2

but it does not print what is required and puts 0 for any item from file1
Can you please help?

LEARN ABOUT SUSE

xzdiff

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp or diff.  If only one file is specified, then the files compared are file1 (which must have a suffix of	a  supported  com-
       pression  format)  and  file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp or diff is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
