[Omaha.pm] 874

[Jay Hannah]

Is the file tab delimited? This seems to work:

 

perl -alnF'\t' -e 'print if ($F[6] == 1)' inputfile.txt

 

HTH,

 

j

The file has too many rows for xls to open :) 
How do I do the following? 

I have 7 column in a row 
A file has say millions of rows 
I would like to do a grep, based on the content of 6th or 7th column. 
e.g. say the 7th column has either a 0 or 1 
I would like to grep those rows that has a value of 1
