The question mark matches *zero* or one of the *preceding* element.
Hence the "s" in "blocks" matches the provided regular expression: "s" followed by *zero* or one "d".
Ah! I see. I need to use a dot instead: nimrodel:~ # cat /proc/partitions | grep -e "sd." 8 0 1993728 sda 8 1 1993608 sda1 or, perhaps, this: nimrodel:~ # cat /proc/partitions | grep -e "sd.\|#blocks" major minor #blocks name 8 0 1993728 sda 8 1 1993608 sda1 - -- Cheers, Carlos E.
