20:16:25 <jbk> hmm.. is there any utility that'd take an input file with ^Hs and the like and just render the final output line?
20:16:36 <jbk> not exactly stripping them as much as just saving the end result
20:16:55 <jbk> e.g. a line 'foo^H^H^Hbar' would just result in 'bar'
20:17:00 <jbk> in the output
20:18:03 <richlowe> ul(1), but perhaps that only processes it '^H_'
20:19:12 <nomad> cat(1)
20:19:34 <nomad> I just created a file /tmp/foo with "foo^H^H^Hbar" and cat /tmp/foo printed bar.
20:20:08 <nomad> ah, never mind. Script shows the control chars still there.
20:20:19 <nomad> just the result I saw on the terminal was the final.
20:23:20 <sommerfeld> col(1)
20:24:33 <sommerfeld> specifically, col -b
20:25:47 <jbk> aha!
20:25:47 <jbk> thanks
20:26:59 <jbk> 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
20:27:15 <sommerfeld> it may do some additional processing you don't want but if the only odd control chars are backspace you should be good.
20:28:09 <richlowe> jbk: I have, in the distant past, used ttyrec for that
20:28:15 <richlowe> usually used to record nethack games, but...
20:28:46 <jbk> it's a VM, so I'm resorting to minicom to access the serial port exposed as a socket
20:30:56 <richlowe> yeah, ttyrec has its own pty, and records input/output, like a tty-oriented script(1) 
20:31:13 <richlowe> so where mdb has paging, etc, etc, it can be your friend in a pinch
20:34:57 <jclulow> jbk: You might enjoy picocom
20:35:41 <jclulow> 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
20:39:47 <richlowe> oh yes, that's a better solution
22:00:15 <jclulow> Oh, also, if it's just a UNIX socket, sercons might help -- https://github.com/jclulow/vmware-sercons
22:00:51 <jclulow> It does even less than picocom haha
22:32:40 <danmcd> I endorse sercons for VMware tty sockets.
