Awk- Indexing a list of numbers in file2 to print certain rows in file1
Hi


Does anyone know of an efficient way to index a column of data in file2 to print the coresponding row in file1 which corresponds to the data in file2 AND 30 rows preceding and after the row in file1.



For example suppose you have a list of numbers in file2 (single column) as follows:


Code:
rs25678
rs25679
rs25680
rs25681
rs25682
rs25683

file1:


Code:
2    9658    rs25681    G    G    GT1=0.20;GT2=0.65;GT3=0.75
2    4258    rs25679    A    G    GT1=0.20;GT2=0.65;GT3=0.76
2    4258    rs25680    T    T    GT1=0.20;GT2=0.65;GT3=0.77

I would like all rows in file1 corresponding to the file2 numbers indexed printed AND 30 rows before and after also printed.

Desired output:




Code:
.    .    .    .    .    .
2    9658    rs25681    G    G    GT1=0.20;GT2=0.65;GT3=0.75
.    .    .    .    .    .
.    .    .    .    .    .
2    4258    rs25679    A    G    GT1=0.20;GT2=0.65;GT3=0.76
.    .    .    .    .    .
.    .    .    .    .    .
2    4258    rs25680    T    T    GT1=0.20;GT2=0.65;GT3=0.77
.    .    .    .    .    .
.    .    .    .    .    .

Dots signify 30 rows of data preceding and after the targeted rows being printed along with targeted rows indexed in file2


Thanks...
