[PLUG] A useful emacs function: wc emulation

[Rich Shepard]

   I've asked quite a few emacs questions here and the answers have always
been helpful. Recently I learned that emacs can do the same thing as the wc
tool: report the number of lines, words, and characters in the buffer. So I
offer the solution for those even less knowledgeable than I on emacs
capabilities.

   Highlight the document (or portion of interest) by setting the mark
(ctrl-spacebar here), navigate to the end of the block to be reported, and
press M-= (here the Meta key is the Esc key).

   Hope that someone, sometime finds this useful, too.

David,

   That's what I thought would work.

   Sure. And that's what I just did with all the June and July
subdirectories. Didn't try deleting all since there's one from today.

   I have a small /tmp partition so I like to keep it uncluttered.

Thanks much,

Rich

You might find the invocation scripts in /etc/bashrc, /etc/profile, or 
/etc/profile.d/*, which are general to all users on the host. In principle, the 
agent should die when you log out, but I've seen some folks out in Google land 
add explicit kills to .bash_logout.

In any case, gpg-agent processes with a parent PID of 1 have been abandoned and 
can be killed. Any /tmp/gpg-* directory older than the last time you logged out 
can be deleted.

Cheers!
David

David,

   Interesting. It's not explicitly called in either of these files.

> - Are you the only person to connect to this host?

   Yes.

> - Could a part of your start up be launching the gpg-agent?

   I suppose.

> - Have you looked at the process list ("ps -ef" or "ps -a") to see if a
> - gpg-agent is running?

   Yes. There are many such processes in various stages of suspension. For
example:

31409 ?Ss 0:30 /usr/bin/gpg-agent --sh --daemon --write-env-file
/home/rshepard/.cache/gpg-agent-info

   No question that something is invoking it, but still no clue what or why.
Having many such processes is not an issue, my interest is clearing /tmp/ of
these small subdirectories now and then.

Regards,

Rich

I believe that's the socket the PGP agent listens on for other PGP work.

[PLUG] /tmp/pgp-*

[Rich Shepard]

   My /tmp/ directory accumulates directories for pgp, one per day. Each
subdirectory contains only a socket and appears to be created when I log in.

   I think these are related in some way to e-mail, incoming or outgoing.

   If I remove all these subdirectories while logged in will today's be
automatically re-generated? If not, I can log out, have root delete them
all, then log in again as a user.
