Extract Lines when Column K is empty with AWK/Perl
- by neversaint
I have data that looks like this:
foo 78 xxx
bar yyy
qux 99 zzz
xuq xyz
They are tab delimited.
How can I extract lines where column 2 is empty, yielding
bar yyy
xuq xyz
I tried this but doesn't seem to work:
awk '$2==""' myfile.txt
