I want to fetch the data based on 1st column and wherever s_ is mentioned and upto s_. for example, I want to filter the data in which k__Bacteria|p__Actinobacteria|c__Actinobacteria|o__Corynebacteriales|f__Corynebacteriaceae|g__Corynebacterium|s__Corynebacterium_durum is there. Can anyone help me regarding this? Thanks

something like this?

$ perl -lane 'if ($F[0]=~/s__Corynebacterium_durum/) { $F[0]=~s/\|t__.*//; print join "\t", @F }' < data.tsv
