Off topic:Quickest Way To Pull A List Of Reads Out Of A Bam File?

Question

[David Quigley]

What is the quickest way find the final aligned locations of a list of reads in BAM file? I can call

samtools view my.bam | grep -e uniqueID1 -e uniqueID2 > output

to grep for uniqueID1 and uniqueID2 in my.bam, but crawling through the SAM is quite slow. I'd like to call:

handyTool extractID my.bam -l listOfIdentifiers > output

and get the SAM line for each identifier found in the BAM. Is there a better way?
