I think there is a bug in AWK in base of FreeBSD 6.x and 7.x (tested on
6.4 i386 and 7.3 i386)
I have this simple test case, where I want 2 columns from GeoIP CSV file:
awk 'FS="," { print $1"-"$2 }' GeoIPCountryWhois.csv
It should produce output like this:
# awk 'FS="," { print $1"-"$2 }' GeoIPCountryWhois.csv | head -n 5
"1.0.0.0"-"1.7.255.255"
"1.9.0.0"-"1.9.255.255"
"1.10.10.0"-"1.10.10.255"
"1.11.0.0"-"1.11.255.255"
"1.12.0.0"-"1.15.255.255"
(above is taken from FreeBSD 8.1 i386)
On FreeBSD 6.4 and 7.3 it results in broken first line:
awk 'FS="," { print $1"-"$2 }' GeoIPCountryWhois.csv | head -n 5
"1.0.0.0","1.7.255.255","16777216","17301503","AU","Australia"-
"1.9.0.0"-"1.9.255.255"
"1.10.10.0"-"1.10.10.255"
"1.11.0.0"-"1.11.255.255"
"1.12.0.0"-"1.15.255.255"
There are no errors in CSV file, it doesn't metter if I delete the
affected first line from the file.
It is reproducible with handmade file:
# cat test.csv
"1.9.0.0","1.9.255.255","17367040","17432575","MY","Malaysia"
"1.10.10.0","1.10.10.255","17435136","17435391","AU","Australia"
"1.11.0.0","1.11.255.255","17498112","17563647","KR","Korea, Republic of"
"1.12.0.0","1.15.255.255","17563648","17825791","CN","China"
"1.16.0.0","1.19.255.255","17825792","18087935","KR","Korea, Republic of"
"1.21.0.0","1.21.255.255","18153472","18219007","JP","Japan"
# awk 'FS="," { print $1"-"$2 }' test.csv
"1.9.0.0","1.9.255.255","17367040","17432575","MY","Malaysia"-
"1.10.10.0"-"1.10.10.255"
"1.11.0.0"-"1.11.255.255"
"1.12.0.0"-"1.15.255.255"
"1.16.0.0"-"1.19.255.255"
"1.21.0.0"-"1.21.255.255"
As it works in 8.1, can it be fixed in 7-STABLE?
(I don't know if it was purposely fixed or if it is coincidence of newer
version of AWK in 8.x)
Should I file PR for it?
