Select row from file and text
Hi all!
I would like to solve a problem but I have no clue of how do it!I will be grateful if someone could help me!
Briefly I have a big file like this:
HTML Code:
>ENSMUSG00000000204 | ENSMUST00000159637
GGCGAGGCTTACGCCATTTTACCTCAGCGAGCATTCATAAAGCTGCGAGCATTCATACAG
>ENSMUSG00000000204 | ENSMUST00000457457
CTGTCCTCTTTCCATGTGCTGTGTGAACCTGGCATGCTGGCTTAGGACATGGCCTGATTC
>ENSMUSG00000006755 | ENSMUST00000457688
GGCGAGGCTTACGCCATTTTGTGTGAACCTGGCATGCTGGCTTAGGACATGGCCTGATTC

and another file like this (it contains all the ID I want obtain freom the previous file!):
HTML Code:
ENSMUSG00000000204
ENSMUSG00000002323
My desired output should be like that (the selected ID and the relative sequence:

HTML Code:
>ENSMUSG00000000204 | ENSMUST00000159637
GGCGAGGCTTACGCCATTTTACCTCAGCGAGCATTCATAAAGCTGCGAGCATTCATACAG

Hello,

Following may help too.

Code:
awk -F" |" 'NR==FNR {a[">"$1];next} ($1 in a){print $0;getline; print $0}' file2 file1


Output will be as follows.
