awk -F, 'NR==FNR{c[$29]=$29;next} NF{print $29 ((c[$29]==$29)?" ":",mismatch")}' $file1 $file2
The value of 29th field, i.e., $29 in file1 was 832.9 and that of file2 was 832.9000. If I compare them they are not equal. I think it is taking as a string rather than a number.
How should I proceed?
1 Answer
awk compares floating point numbers:
I just wrote a new script:
paste \
<(awk -F, '{print $29}' file1 ) \
<(awk -F, '{print $29}' file2 ) \
| awk '{print $1; print $2; print ($1==$2)?"match" :"mismatch"}'
If you do not like breaks, then use printf instead of print.
Example
Input files
cat file1
12,2,12,12,12,12,3,2,53,6,5474,346,567,6578,89,7689,7,987,69869,1,4,5,4,3,4,2,6,21,832.9,9,2
12,2,12,12,12,12,3,2,53,6,5474,346,567,6578,89,7689,7,987,69869,1,4,5,4,3,4,2,6,21,12.329,9,2
cat file2
12,2,12,12,12,12,3,2,53,6,5474,346,567,6578,89,7689,7,987,69869,1,4,5,4,3,4,2,6,21,832.9000,9,2
12,2,12,12,12,12,3,2,53,6,5474,346,567,6578,89,7689,7,987,69869,1,4,5,4,3,4,2,6,21,832.9000,9,2
Output
% paste <(awk -F, '{print $29}' file1 ) <(awk -F, '{print $29}' file2 ) | awk '{print $1; print $2; print ($1==$2)?"match" :"mismatch"}'
832.9
832.9000
match
12.329
832.9000
mismatch
