Hello experts, I am relatively new in perl (1 month) and have come up with the following problem. I sincerely hope I will get some direction from this forum. I have two text files. File 1 content look like 
ABCDEFG0098GHT    J19.17
ABCDEFG0141314    J19.1
ABCDEFGQQ76890    WOK2234
ABCDEFG0Y56421    POK1
ABCDEFG00Z7657    FVT1

[download]
and so on Now file 2 looks like this: 
>ABCDEFG0098GHT
ATTATGCGCGCGCTCGCTGCTCG
>ABCDEFG0098GHT
ATTATGCGCGCGCTCGCTGCTCG
>ABCDEFGQQ76890
TAGACAGATAGACAGATGACAGAT

[download]
Now I want to compare these two files. I specifically want to compare first column data of file 1 with that of the text present after the > sign in file 2 (data like ABCDEFG0098GHT). I only want to keep those data in file 2, that matches with POK or WOK in file 1. Can any body please help
