No. I thought your directions were quite clear:
Quote:
$5 in line1(file1) matches to $4 in line1(file2) , get value of $2 from line1(file2)
$2 in line1(file2) matches to $2 line2(file2) , get $1,$3,$4 from that line and append after $5 line1(file1)
Same logic to be used for rest
There will be always 2 occurrences where $2 in line2 matches
That said to me that if $5 in File1 matches $4 in File2, get and print the contents of the 2nd line in File2 that matches $2. I didn't see anything there that made me think you were trying to get "the other line" that matched $2 rather than "the 2nd line" that matched $2.

If I correctly understand your new requirements, try:
Code:
awk '
BEGIN {	FS = ",| *$"
	OFS = ","
}
NR == FNR {
	data[$2 SUBSEP (2 - c[$2]++)] = $1 OFS $3 OFS $4
	lf[$4] = $2 SUBSEP c[$2]
	next
}
{	print $0, data[lf[$5]]
}' File2 File1

which, with File1 containing:
Code:
000433,ds00d11,tdev,ds00d11_view,0CD3
000433,ds00d11,tdev,ds00d11_view,114D
000433,ds00d12_34,tdev,ds00d12_view,114F
000433,ds00d12_34,tdev,ds00d12_view,132D

and File2 from post#1 in this thread:
Code:
CG01_ds00d11_drs,rs1_ds00d11_0CD3_114D,000433,0CD3                            
CG01_ds00d11_drs,rs1_ds00d11_0CD3_114D,000566,114D                          
 CG02_ds00d12_34_drs,rs2_ds00d12_132D_114F,000433,132D
CG02_ds00d12_34_drs,rs2_ds00d12_132D_114F,000566,114F

produces the output:
Code:
000433,ds00d11,tdev,ds00d11_view,0CD3,CG01_ds00d11_drs,000566,114D
000433,ds00d11,tdev,ds00d11_view,114D,CG01_ds00d11_drs,000433,0CD3
000433,ds00d12_34,tdev,ds00d12_view,114F, CG02_ds00d12_34_drs,000433,132D
000433,ds00d12_34,tdev,ds00d12_view,132D,CG02_ds00d12_34_drs,000566,114F

Is that what you want?
