Compare Fields from two text files using key columns
Hi All,
I have two files to compare. Each has 10 columns with first 4 columns being key index together. The rest of the columns have monetary values.
Using Perl, I want to read one file into hash; check for the key value availability in file 2; then compare the values in the rest of 6 columns; report the differences found.
The files are comman separated and do not have header
Here is the sample file:
File A:
File B:
Output:
Any help would be appreciated. I am able to come up with the script in Bash, but not very comfortable with the concept of Hash in Perl and also setting up key index columns.
Thanks!

I am trying to join/paste columns from two files for the rows with matching first field. Any help will be appreciated.
Files can not be sorted and may not have all rows in both files.
Thanks.
File1
aaa 111
bbb 222
ccc 333
File2
aaa sss mmmm
ccc kkkk llll
