AWK If/ElseConditional Problem
- by neversaint
I have a data that looks like this:
foo foo scaffold_7 1 4845 6422 4845
bar bar scaffold_7 -1 14689 16310 16310
What I want to do is to process the above lines
where I just want to print column 1,2,3, 7 and one more column after 7th.
But with condition when printing column 7 onwards.
Below is my awk script:
awk '{
if ($4=="+") { {end=$6-$5}{print $1 "\t" $2 "\t" $3 "\t" $4 "\t" $7 "\t" end+$7} }
else
{end=$6-$5}{print $1 "\t" $2 "\t" $3 "\t" $4 "\t" $7-end "\t" $7}
}'
But why it doesn't achieve the desired result like this?
foo foo scaffold_7 1 4845 6422
bar bar scaffold_7 -1 14689 16310
Note that the arithmetic (e.g. $7-end or end+$7) is a must. So we can't just swap column
from input file. Furthermore this AWK will be inside a bash script.
