awk '{ print FILENAME, FNR, NR }' old.csv replacement.csv
will output
old.csv 1 1
old.csv 2 2
old.csv 3.3
replacement.csv 1 4
replacement.csv 2 5
replacement.csv 3 6
so, you can check in your script which inputfile you're reading from bye
comparing FNR and NR
so, i would start with:
awk 'NR=FNR{ repl[$1]=substr($0,length($1+1)); next; } { rest of your
script, which checks if repl[] things are contained in file old.csv }'
replacement.csv old.csv
