can shell mode keep a log?

can shell mode keep a log?

[Samuel Wales]

is it possible and reasonable to log everything in every shell buffer
to a file?  i can imagine lots of output, but i could have the logs go
into an auto-expired dir.  but would performance ok?

can shell-mode run tee?  If yes it ought to be possible.  That may not
even be necessary if shell-mode can create and save history.
run command in shell-mode you want logged, and suffix it with | tee
<file>.log where <file> is the name of the log to save.
This is one problem I have had outside of shell-mode and finally learned
how to use the tee command.

Does it have to be automatic?  If not, you can always just write out the
contents of a buffer using M-x write-file.

A slightly more "automatic" alternative is to save the buffer using
the facilities in midnight.el or something similar.

Re: can shell mode keep a log?

[Samuel Wales]

thank you all for your replies.  here are why i think those soliutions
will not work.

i need ti to be automatic, for the entire shell session, for all
comand including prompts,  sort of like typescrpt ut that would likely
have issues i am unware of such as commands outputtig to termianl or
osehting.

iow a complete history o the shell sessions in my shell buffers, saved
continuously or continually to files efficiently.

it is not for a ingle command.  i would indeed use tee for such things.

soign write-file is good for manual saves and i should remember it
morel  although i think that changes the visited filename or so.  but
it is not the automatic solution i am looking or.  i want a log of the
session.

thank youl.

Of course it should be.

Of course it should be a general solution.

You can enable auto-save-mode in the shell buffer. Make sure to read the
manual about the options to control its application.

Once you use write-file, from then on, auto-save-mode is enabled in it
by default.

You can probably use shell-mode-hook to do one of the above in all such
buffers.

comint scrolls off top.  would auto save mode take that into account?

idk about shell-mode-hook, but i was thinking
comint-preoutput-filter-functions would maybe allow saving each set of
output [idk if per chunk of output or per prompt pair], but this
definitely seems like a feature only i need.  :/
