UNIX for Dummies Questions & Answers

Hi,

I have a space delimited text file that looks like the following:


250 rs10000056 0.04 0.0888 4 189321617
250 rs10000062 0.05 0.0435 4 5254744
250 rs10000064 0.02 0.2403 4 127809621
250 rs10000068 0.01 NA
250 rs1000007 0.00 0.9531 2 237752054
250 rs10000081 0.03 0.1400 4 17348363
250 rs10000085 0.01 0.3630 4 61435320
250 rs10000088 0.01 NA
250 rs10000092 0.00 0.8284 4 21895517
250 rs1000012 0.00 0.6633 9 135703041
250 rs10000121 0.00 0.6653 4 157574035
250 rs10000132 0.00 0.9437 4 7399669

I would like to remove all the lines that contain NA. How do I go about doing that? Thanks!

Code:

egrep -v 'NA' File

Code:

grep -v NA infile > outfile

Assuming a space in front and it's at the end of a line:

Code:

sed '/ NA$/d'  inputfilename > outputfilename

Code:

 
awk ' ! /NA/ {print $0}' input > output

Wow. It even works.

Code:

require.paths.unshift('/usr/local/lib/node_modules');
var Lazy=require("lazy");

new Lazy(process.stdin)
    .lines
    .forEach(
	function(line) 
	{ 
            var s = line.toString();
	    if (! s.match(/NA/)) console.log(s); 
	}
    );

process.stdin.resume();

Code:

sudo npm -g install lazy
...
node select.js <INPUTFILE
...
