Hi All,

@derobert

How are you

@Gilles when is /etc/environment read? I am defining a variable there but can't seem to get it to work in either login or non-login shells.

@terdon sorry to jump in, but is this for AIX? If so, getty (console) or srcmstr (sshd) would have to be restarted

@JeffSchaller No, it's for Linux but it shouldn't make any difference. I'm wondering when that file is read, not how to read it. It's supposed to be read automatically, I thought by login shells, but doesn't seem to be.

@terdon according to serverfault.com/questions/375252/… it apparently comes in via pam, maybe pam_env.so ?

/etc/environment empty in redhat, contains PATH in ubuntu.

@JeffSchaller Hmm. The answer mentioning pam also states:

> All of this, of course, relies on whatever binary you're using (crond, login shells etc) are compiled against PAM.

Which would suggest login shells read it but mine don't. I'm not entirely sure what kind of pam setup I have though. I've never touched it, only whatever Debian set up.

@Archemar Empty in Debian as well but I'm wondering when it's read.

Jeff found a post that suggests it is only read by PAM which may very well be the case.

see /etc/pam.d/login, how as for question in U&L, unless you modify it quiet often, there is no need to source it for EVERY terminal opened. (unless OP has an XY problem)

@terdon should be read on actual log in, possibly only on the console.

% cat /etc/environment
#
# This file is parsed by pam_env module
#
# Syntax: simple "KEY=VAL" pairs on separate lines
#

on my system pam_env.so is brought in for session

@terdon my understanding of that (as @derobert notes) is that it is processed at initial login (console, X, ssh)

Anyone here using gscan2pdf? I've asked this before.

about once a week for the last month :)

udev rules driving me nuts is a great question title. I think that's the whole point of udev rules.

status-by-design

Thanks @Gilles @derobert @casey. ssh localhost did the trick.

@casey gscan2pdf?

I don't remember you mentioning it before. I might have forgotten.

@derobert So what's the answer?

@FaheemMitha no, i was referencing the "I've asked this before" part

I've never used it

@casey Oh, that. If you say so. I don't keep track.

neither do I. I put it in the search box

The gscan2pdf author has been fairly helpful re bug fixing but doesn't seem inclined to actually answer questions.

@casey Ok.

I'm not sure if that'll work, surprising if OP didn't try it.

@derobert Yes, I saw that. He's wondering why one worked and the other didn't. Which is a reasonable thing to wonder, I think.

@FaheemMitha Well, he tried SUBSYSTEMS=="usb" and SUBSYSTEM="usb-serial" ... for some reason changing two things instead of just one.

What is the difference between usb and usb-serial, anyway?

@derobert Yes, I noticed. Maybe the other combinations didn't work for him. Though he should have mentioned that, if not.

unix.stackexchange.com/review/suggested-edits/110406

yeah for duplicate accounts!

@derobert He proposed an edit on an answer from another account?

Couldn't it be a different person with a similar name?

@FaheemMitha yeah, but I'm 99% sure both accounts are him. One is an unregistered account.

@derobert ok

Similar name, one unregistered, editing to respond to comments on a recent question... hard to believe they're different people.

@derobert Fair enough. Perhaps politely suggest he merge the accounts? Possibly some browser/cookie artifact.

... already did.

@derobert ok

@derobert his posts are fixed up now. I copied his repost into his original and showed him how to delete the repost...

@casey thank you

Could someone protect this? It's received quite a few rubbish answers. Thanks.

@FaheemMitha done

@derobert Thanks. How much rep is needed?

@FaheemMitha 15k unix.stackexchange.com/help/privileges/protect-questions

I think that's actually the first time I've gotten to use that feature.

On any SE site.

@derobert Sorry, I was being lazy.

@derobert Well, this seems like a reasonable application to me.

@FaheemMitha You don't have enough rep to do it

Oh, yeah, too lazy to check the help center

@FaheemMitha Yeah, that's what its for.

@derobert I know. Short by 1.5k approximately.

I'm surprised the folks deleting the Sandesh answer didn't protect the question. Though I guess the review queue allows enough <20k rep folks to delete an answer, so maybe none of them could.

@derobert they could always ask here.

Indeed.

Or flag it and ask a mod to do it.

True.
