hi ,

from the awk command i'm getting the output where the 2nd column of both are match in row wise,
if it present in that same column some where else, I cannot get the correct output.
awk 'FNR==NR {a[$1]=$5;next} $1 in a {if ($5==a[$1]) t=0; else {t=$5-a[$1]};print $0,t}' file.tsv file2.tsv

please check the thread Compare two numbers which present in two different files

col1 col2 col3
11 15465 13.60
12 24656 11.00
13 245896 754.00

col1 col2 col3
11 245896 754.00
12 15465 13.60
13 24656 11.00

this will give the wrong output

I recognize that for some people here, english is not the primary language. I do not think you explained this well.

  1. show input file

  2. show your command

  3. show what you are getting

  4. show what you want to get for output.

Hi,

here i have given the input files and output files, and awk command
awk 'FNR==NR {a[$1]=$4;next} $1 in a {if ($4==a[$1]) t=0; else {t=$4-a[$1]};print $0,t}' file1.tsv file2.tsv

i have to find the COL1 number in file2 and get the difference of the matched number's COL3 Value that is i have to find the 14150524 in file2 and take a difference of 39.88 - 37.88 and the result i want is like 10527 14150524 Sa 39.88 -2

Assuming you want result -2 you may want t=a[$1]-$4 (scanning file2 at first)

awk 'FNR==NR{a[$1]=$4;next}$1 in a{t=a[$1]-$4;print $0,(FNR==1)?"":t}' file2 file1

with a bit of formating

awk 'FNR==NR{a[$1]=$4;next}$1 in a{t=a[$1]-$4;printf"%-8s %8s %-4s %8s %8s\n",$1,$2,$3,$4,(FNR==1)?"COL4":t}' file2 file1

$ awk 'FNR==NR{a[$1]=$4;next}$1 in a{t=a[$1]-$4;printf"%-8s %8s %-4s %8s %8s\n",$1,$2,$3,$4,(FNR==1)?"COL4":t}' f2 f1
