Re: [TUHS] run commands at login in v6 and stty

On 26 Feb 2022 14:39 -0600, from will.senn(a)gmail.com (Will Senn): https://minnie.tuhs.org/cgi-bin/utree.pl?file=V6/usr/source/s2/sh.c it doesn't look like you can, at least not in the way we're used to today of having the shell execute a magic file (such as ~/.bashrc) during startup. I also don't see anything in https://minnie.tuhs.org/cgi-bin/utree.pl?file=V6/etc/passwd that suggests that the shell can be specified on a per-user basis the way we're used to being able to do today, so the hack of making that point to a program that does some initial setup and then launches the shell proper also might not be readily available. On the other hand, https://minnie.tuhs.org/cgi-bin/utree.pl?file=V7/usr/src/cmd/sh/main.c looks like it includes such support; see the section surrounding the pathopen(nullstr, profile) call toward the bottom of main(). (Beware: it's written in Bourne C.) I won't say "you can't do it in V6", because I don't know things anywhere near well enough to say that, but it doesn't look entirely trivial at least, and it seems to have been added in V7's sh. -- Michael Kjörling • https://michael.kjorling.se • michael(a)kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”
