UNIX for Dummies Questions & Answers

Can someone help me to do the following

I have two files

file one

Code:

123456
789012
345678
901234
567890

file two

Code:

abcdef
ghklmn
opqrst
901234
567890
uvwxyz
123456

I would like to do tail on the last two lines from file one,
match the string in file two and then delete all lines above matching string, and send output to file three.

File three should look

Code:

uvwxyz
123456

My search is always based on the last two lines from file one, and that changes every day.

Thank you for your help.

And I forgot to mention, I searched forum and could not find any previos topics that could provide the solution to my issue.

this seems to work:

Code:

$ awk 'FNR==NR{a=b;b=$0;next}p{print;next}$0==b&&a2==a{p=1}{a2=$0}' file1 file2
uvwxyz
123456

FNR==NR is true for first file. so while reading first file we end with a being next to last line, and b being the last line. Then while reading file2 we search for a line that matches b and check that the previous one also matches a and print everything after it.
