... but what is the point ? grep won't write anything to stderr (will it ?).
If /proc/scsi/scsi does not exist, cat will still generate an error message
to stderr, which is not redirected.
Now, if you removed a spurious process, it would be better,
if grep 'Type: Sequential-Access' /proc/scsi/scsi >/dev/null 2>&1
or even get grep to fo the business for you,
if grep -qs 'Type: Sequential-Access' /proc/scsi/scsi
