Consider this input file:

bam/pfg413T.GRCh38DH.target.bai
bam/pfg413T.GRCh38DH.target.bam
bam/pfg413T.GRCh38DH.target.bam
bam/pfg416G.GRCh38DH.target.bai
bam/pfg416G.GRCh38DH.target.bam

How can I combine the following multiple grep -E into one grep -E pipe ?

readlink -f exomesinglesample_out/bam/pfg* | grep -E 'pfg[0-9]*G' | grep -E 'bam$'

`grep 'pfg[0-9]*G.*bam$'`? – Wiktor Stribiżew Feb 23 '21 at 09:20
