printing lines where certain columns do not match, with awk
awk, matching
Solution
just fix your codes:
awk '($3 != $4) && !($3=="C" && $4=="T")' file
Problem
I have a tab separated file like this: ``` 1 10502 C T 1 10506 C T 1 10567 G A ... ``` And I'm trying to print out all lines where `column 3 != column 4`, excluding the cases where `column 3 = C and column 4 = T`. I tried ``` awk '{ if (($3 == $4) || ($3 == C && $4 == T) ) next ; else print $0; }' ``` but I'm not sure what's going wrong...
