next in thread | raw e-mail | index | archive | help
I've had this patch lying around here for a while - it adds a simple
SIGINFO handler to fsck(8) so you can tell what it's doing by
pressing Ctrl-T. The output will be something like:
^T
load: 0.14 cmd: fsck_ufs 10473 [physstr] 2.12u 0.30s 8% 2016k
/dev/da0s1f: phase 1: cyl group 26 of 60 (43%)
^T
load: 0.12 cmd: fsck_ufs 10473 [physstr] 4.00u 0.49s 11% 2804k
/dev/da0s1f: phase 2: dir 488 of 27965 (1%)
Is this a feature we want in fsck? It doesn't really help except
to give you something to do while waiting for a huge filesystem to
be checked :-) I guess it also allows you to see if fsck is actually
getting anywhere.
