How to merge files depending on a string in a specific column - bash

Question

I have two files that I need to merge together based on what string they contain in a specific column.
File 1 looks like this:
1 1655 1552 189
1 1433 1552 185
1 1623 1553 175
1 691 1554 182
1 1770 1554 184
1 1923 1554 182
1 1336 1554 181
1 660 1592 179
1 743 1597 179
File 2 looks like this:
1 1552 0 0 2 -9 G A A A
1 1553 0 0 2 -9 A A G A
1 1554 0 751 2 -9 A A A A
1 1592 0 577 1 -9 G A A A
1 1597 0 749 2 -9 A A G A
1 1598 0 420 1 -9 A A A A
1 1600 0 0 1 -9 A A G G
1 1604 0 1583 1 -9 A A A A
1 1605 0 1080 2 -9 G A A A
I am wanting to match column 3 from file 1 to column 2 on file 2, with my output looking like:
1 1655 1552 189 0 0 2 -9 G A A A
1 1433 1552 185 0 0 2 -9 G A A A
1 1623 1553 175 0 0 2 -9 A A G A
1 691 1554 182 0 751 2 -9 A A A A
1 1770 1554 184 0 751 2 -9 A A A A
1 1923 1554 182 0 751 2 -9 A A A A
1 1336 1554 181 0 751 2 -9 A A A A
1 660 1592 179 0 577 1 -9 G A A A
1 743 1597 179 0 749 2 -9 A A G A
I am not interested in keeping any lines in file 2 that are not in file 1. Thanks in advance!

Answer 1

Thanks to #Abelisto I managed to figure something out 4 hours later!
sort -k 3,3 File1.txt > Pheno1.txt
awk '($2 >0)' File2.ped > Ped1.ped
sort -k 2,2 Ped1.ped > Ped2.ped
join -1 3 -2 2 Pheno1.txt Ped2.ped > Ped3.txt
cut -d ' ' -f 1,4,5 --complement Ped3.txt > Output.ped
My real File2 actually contained negative values in the 2nd column (thankfully my real File1 didn't have any negatives) hence the use of awk to remove those rows

Answer 2

Using awk:
awk 'NR == FNR { arr[$2]=$3" "$4" "$5" "$6" "$7" "$8" "$9" "$10 } NR != FNR { print $1" "$2" "$3" "$4" "arr[$3] }' file2 file1
Process file2 first (NR==FNR) Set up an array called arr with the 3rd space delimited field as the index and the 3rd to 10th fields as values separated with a space. Then when processing the first file (NR!=FNR) print the 1st to the 4th space delimited fields followed by the contents of arr, index field 3.

Answer 3

Since $1 seems like constant 1 and I have no idea about rowcounts of either file (800,000 columns in file2 sounded a lot) I'm hashing file1 instead:
$ awk '
NR==FNR {
a[$3]=a[$3] (a[$3]==""?"":ORS) $2 OFS $3 OFS $4
next
}
($2 in a) {
n=split(a[$2],t,ORS)
for(i=1;i<=n;i++) {
$2=t[i]
print
}
}' file1 file2
Output:
1 1655 1552 189 0 0 2 -9 G A A A
1 1433 1552 185 0 0 2 -9 G A A A
1 1623 1553 175 0 0 2 -9 A A G A
1 691 1554 182 0 751 2 -9 A A A A
1 1770 1554 184 0 751 2 -9 A A A A
1 1923 1554 182 0 751 2 -9 A A A A
1 1336 1554 181 0 751 2 -9 A A A A
1 660 1592 179 0 577 1 -9 G A A A
1 743 1597 179 0 749 2 -9 A A G A
