hmm.. is there any utility that'd take an input file with ^Hs and the like and just render the final output line?

not exactly stripping them as much as just saving the end result

e.g. a line 'foo^H^H^Hbar' would just result in 'bar'

in the output

ul(1), but perhaps that only processes it '^H_'

cat(1)

I just created a file /tmp/foo with "foo^H^H^Hbar" and cat /tmp/foo printed bar.

ah, never mind. Script shows the control chars still there.

just the result I saw on the terminal was the final.

col(1)

specifically, col -b

aha!

thanks

i'm trying to track down a panic in ahci... it's prior to any dump devices being available, so i'm trying to log the kmdb session to save the output

it may do some additional processing you don't want but if the only odd control chars are backspace you should be good.

jbk: I have, in the distant past, used ttyrec for that

usually used to record nethack games, but...

it's a VM, so I'm resorting to minicom to access the serial port exposed as a socket

yeah, ttyrec has its own pty, and records input/output, like a tty-oriented script(1)

so where mdb has paging, etc, etc, it can be your friend in a pinch

jbk: You might enjoy picocom

What I recall is that minicom was a visual mode thing, whereas picocom just attaches the serial port to your existing terminal without doing its own layout

oh yes, that's a better solution

Oh, also, if it's just a UNIX socket, sercons might help -- github.com/jclulow/vmware-sercons

It does even less than picocom haha

I endorse sercons for VMware tty sockets.
