I have to extract the values which are greater than or equal to 0.01 from column number 6 of tab-delimited file(My files contain more than 6 columns). I had tried with following code for i in $(find ./ pwd -name "BC_4_*_*shift.txt" ); do awk -F"\t" 'NR==1 || $6>=0.01' $i > $i"_"ctdna_freq.txt; done to write this code I had taken help from get all rows having a column value greater than a threshold, Using this code I am able extract values from 6th column which are greater than 0.01 but I am not able to extract the values which are equal to 0.01 following is my input file

I have to extract the values which are greater than or equal to 0.01 from column number 6 of tab-delimited file(My files contain more than 6 columns). I had tried with following code

for i in $(find ./ `pwd` -name "BC_4_*_*shift.txt" ); do
    awk -F"\t" 'NR==1 || $6>=0.01' $i > $i"_"ctdna_freq.txt;
done

to write this code I had taken help from get all rows having a column value greater than a threshold, Using this code I am able extract values from 6th column which are greater than 0.01 but I am not able to extract the values which are equal to 0.01 following is my input file
