Comparing 2 columns from different files print matching columns - bash

Question

I know similar questions have been asked which has led me write the current code but I am still not able to get the correct output.
Question:
If Column 1 (in file 1) matches Column 5 (in file 2), print all columns in file 2 and columns 3 and 4 (in file 1) to a new file.
File 1 (tab-delimited)
NJE_00001 rmf 6.2 Ribosome modulation factor
NJE_00002 rlm 7.1 Ribosomal RNA large subunit methyltransferase
NJE_00003 gnt 6.2 putative D-xylose utilization operon
NJE_00004 prp 4.1 2-methylisocitrate lyase
File 2 (tab-delimited)
AFC_04390 rmf 5.6 protein1 NJE_00001
AFC_04391 rlm 2.5 protein54 NJE_00002
AFC_04392 gnt 2.1 protein8 NJE_00003
AFC_04393 prp 4.1 protein5 NJE_00004
Desired Output (tab-delimited)
AFC_04390 rmf 5.6 protein1 NJE_00001 6.2 Ribosome modulation factor
AFC_04391 rlm 2.5 protein54 NJE_00002 7.1 Ribosomal RNA large subunit methyltransferase
AFC_04392 gnt 2.1 protein8 NJE_00003 6.2 putative D-xylose utilization operon
AFC_04393 prp 4.1 protein5 NJE_00004 5.9 2-methylisocitrate lyase
What I've tried:
awk -F '\t' 'NR==FNR {a[$1]=$3"\t"$4; next} ($5 in a) {print $1 "\t" $2 "\t" $3 "\t" $4 "\t" $5 "\t" a[$1]}' file1.tsv file2.tsv > file.out
awk -F '\t' 'NR==FNR {a[$1]=$2; next} {if ($5 in a) {print $1 "\t" $2 "\t" $3 "\t" $4 "\t" $5 "\t" a[$1]}}' file1.tsv file2.tsv > file.out
awk -F '\t' 'NR==FNR {h[$1]=$3"\t"$4; next} ($5 in h) {print $1 "\t" $2 "\t" $3 "\t" $4 "\t" $5 "\t" h[$1]}' file1.tsv file2.tsv > file.out
They've all given the same outputs which is identical to file 2. Any help would be much appreciated! Thank you!

Answer 1

$ awk '
BEGIN { FS=OFS="\t" }
NR==FNR { a[$1]=$3 OFS $4; next }
{ print $0, a[$5] }
' file1 file2
AFC_04390 rmf 5.6 protein1 NJE_00001 6.2 Ribosome modulation factor
AFC_04391 rlm 2.5 protein54 NJE_00002 7.1 Ribosomal RNA large subunit methyltransferase
AFC_04392 gnt 2.1 protein8 NJE_00003 6.2 putative D-xylose utilization operon
AFC_04393 prp 4.1 protein5 NJE_00004 4.1 2-methylisocitrate lyase

Answer 2

Could you please try following.
awk '
FNR==NR{
val=$1
$1=$2=""
sub(/^ +/,"")
a[val]=$0
next
}
($NF in a){
print $0,a[$NF]
}
' Input_file1 Input_file2
Explanation: Adding detailed explanation for above code.
awk ' ##Starting awk program from here.
FNR==NR{ ##Checking condition FNR==NR which will be TRUE when Input_file1 is being read.
val=$1 ##Creating variable val which has $1 of current line.
$1=$2="" ##Nullifying first and second fields here.
sub(/^ +/,"") ##Substituting initial space with NULL in current line.
a[val]=$0 ##Creating an array named a with index val and value of current line.
next ##next will skip further lines from here.
}
($NF in a){ ##Checking condition if $NF(last field of current line) is present in array a then do following.
print $0,a[$NF] ##Printing current line with array a with index $NF value.
}
' file1 file2 ##Mentioning Input_file names here.

Answer 3

As long as your files are sorted on the first and fifth columns respectively like in your sample, it's easy to do with join
join -t$'\t' -11 -25 -o 2.1,2.2,2.3,2.4,2.5,1.3,1.4 file1.tsv file2.tsv > joined.tsv
If not sorted, use <(sort -t$'\t' -k1,1 file1.tsv) and/or <(sort -t$'\t' -k5,5 file2.tsv) instead of just the filename as arguments to join.
