Intersect of two columns in two separate files
Hi,
I have a file like this:
Code:
abc
def
ghi
jkl
mno

My second file is like this (tab delimited):
Code:
adsad	sdfsdf	dfdf
wads	abc	dfdsf
sdsf	jkl	sfsdf
dsfds	sdfd	reor
zxczd	dsf	sff

Now, I want the code to report the lines (from file2) which have common strings in column 2 with the first file. So the output should be like this:
Code:
wads	abc	dfdsf
sdsf	jkl	sfsdf

Could anybody please help?

Thanks

I don't know much about unix because it's not my field of study. I know that this code returns the common strings between the two files but have no idea how to manipulate it for my purpose.
Code:
awk 'NR==FNR{a[$0]=$0;next}a[$0]' file1 file2

Try this if all columns needs to be compared:
Code:
awk 'NR==FNR{A[$1];next}$1 in A || $2 in A || $3 in A' file1 file2

If just column 2 needs to be compared:
Code:
awk 'NR==FNR{A[$1];next}$2 in A' file1 file2
