OK, thanks everybody.

Had to use egrep. This works:

PATTERN='https?://[^/]*\.in(/.*)*'
egrep $PATTERN file.of.links > links.in

Covers cases with https and where nothing follows the .in

One extra change I'd make, to make it more obvious you are checking for a
literal dot and not intending to escape, use [.] instead of \.

So,

egrep 'https://[^/]*[.]in(:[0-9]+)?/' file.of.links > links.in

I did this twice. In both cases I had a dual-boot Windows plus Linux / 
and /home and swap. In one case it worked perfectly. In the other case,
it turned the two Linux partitions (but not swap) into one big 
"unallocated" partition. I never knew why. I did not try to rescue the
"unallocated" partition--it might have had the files and data buried in 
it, but I don't know. So my best advice to you is to backup anything
you want to keep onto a USB drive or something before you do it. And of 
course, Windows will almost certainly wipe out your
dual-boot, so you will have to set that back up. (Windows can't seem to 
install anything big without rebooting a time or two, so it sets
up its own boot manager.) Oh, I tried to do it one other time, with some 
poorly documented program that was supposed to let
Windows operate the dual-boot function. This time I wound up losing 
Windows 7, so I had nothing to upgrade from. Altho I really
hardly ever use Windows, there are one or two things that I need it for, 
and I usually need it on _that_ machine, so I bought a new

Win 10-Pro disk and installed it, and then reinstalled Linux. Phooey!

Re: OT: grep and regex patterns

[Chris Adams]

Once upon a time, Mike Wright  said:
> PATTERN="^.*http:\/\/.*\.in.*$"
> grep $PATTERN < file.of.links >links.in

Several issues I see:

- it appears you are using a shell variable to pass the pattern; since
  you are using double quotes, shell interpolation occurs, so all the
  escaping \ characters are just escaping from the shell - grep just
  sees "^.*http://.*.in.*$;

- you'll match any URL with "in" in it anywhere, not just in the
  hostname portion

- "^.*" and ".*$" are essentially useless, because they match anything
  at the start and end of the line respectively (which, since by default
  a pattern isn't anchored to the start/end, is not needed)

- you don't need to escape the / (so // is fine instead of the "leaning
  toothpicks" of "\/\/")

- if you are going to use a variable to set the pattern, you need to use
  double quotes around it when it is used

- may not be a problem for your case, but you won't match HTTPS URLs

- minor nit: grep reads from a file, so shell redirection is superfluous

Putting all that together, I'd recommend:

  PATTERN='https?://[^/]*\.in/'
  grep "$PATTERN" file.of.links > links.in

or just:

  grep 'https?://[^/]*\.in/' file.of.links > links.in

Only potential oddity would be if you have URLs with non-standard ports
specified (like "https://foo.in:8080/;); to match that, you could use
egrep instead (extended regex):

  egrep 'https://[^/]*\.in(:[0-9]+)?/' file.of.links > links.in

OT: grep and regex patterns

[Mike Wright]

Hi all,

There is a file with a collection of links from global sites.  While 
trying to sort the links into categories I'm catching the wrong things.


e.g. find links from India:

PATTERN="^.*http:\/\/.*\.in.*$"
grep $PATTERN < file.of.links >links.in

Even though the "." in front of "in" is escaped with "\" PATTERN is 
catching any text containing "in".  This is obviously not what is intended.


Any one out there point me to the error of my ways?

TIA,
Mike Wright

Note that command must be run as root. If you are a mortal user with a

sudo setsebool -P unconfined_mozilla_plugin_transition on

and put in your (mortal user) password when asked.

Sounds like the system processes think they are in a different time zone than 
user
processes.  This can sometimes happen when system time is set to a UTC offset 
while users
have their zones set to a local zone which has "standard" time as well as 
"summer" time. 

But, your email address would suggest you're located in Australia and now on 
"standard"
time so they should match up.

So, it isn't clear why this is happening in your case.

I would check the output of "hwclock" as well as check what /etc/localtime 
links to as a
start.

(just closing this "properly".  my apologies for the earlier mistake in 
the subject line.)


Neither VLC nor Amarok seem to come with Fedora.  But late last night, I 
found VLC with "apper" and downloaded it.  I got it to work for the two 
radio stations.  It did not help with "Pipedreams".  (By the way, 
Pipedreams is *not* a radio station.)  Now this morning, the buttons on 
the second link 
(http://www.yourclassical.org/programs/pipedreams/episodes) for 
Pipedreams does work!  The buttons on the first link 
(http://pipedreams.publicradio.org/listings/2016/1628/) still don't 
work.  I'll open a new thread on that later, mainly focused on adobe 
applications.  (see the thread "application to listen to on-line 
broadcasts?  [SOLVED]")


Since VLC worked, I did not try the others.

I thank Rick, Andras, and Fred for their help.

Bill.

Systemctl status network.service Displays Wrong Timestamp on Output Display

[Stephen Morris]

Hi,

Below are the messages I get when I issue command 'systemctl status 
network.service'. The time stamp on the messages is incorrect by 1 hour, 
can anyone tell me why?


Also the messages have indicated that interface Linksys07468_5Ghz 
was able to be activated ok (this is the 5GHz wifi interface to my 
router), if that is the case why is that wifi connection not usable, and 
why has it not listed the Linksys07468 interface which my 2.4GHz wifi 
interface to my router, which networkmanager will quite happily 
activate, whereas networkmanager refuses to activate the 
Linksys07468_5Ghz interface.

Looks like yes:

Do you have gstreamer-plugins-ugly installed? Looking at the various
source modules, Gst* comes from that package.

radiotray and gstreamer plugins

[Jon LaBadie]

The current thread on "listening to online broadcasts"
stimulated me to ask about problems with the one I
like, "radiotray".

A number of stations I try to listen to, including some
preconfigured ones, fail with a list of procedures from
gstreamer that suggest a plugin is missing.  But it
does not say which.  As far as I can tell I have just
about every gstreamer plugin installed and see no way
to determine what may be missing.

Scouring the net comes up with lots of reports of
similar error listings, but no "solution" has worked
in my environment.

Here is a sample listing:

  gstdecodebin2.c (3576)
  gst_decode_bin_expose():
  GstPlayBin2:player
  GstURIDecodeBin:uridecodebin9
  GstDecodeBin2:decodebin29:

I have the same problem on Fedora 22 and 24.

Neither one is installed by default.  Amarok is in the regular Fedora

set that up.

Both of those pages work for me.  One plays in the page, I assume HTML5. 
 Since it's mp3, I'm guessing that somewhere along the way of 
installing the other applications, the mp3 codec from rpmfusion was also 
installed, which is why it suddenly started working.  The other page 
opens a popup window and uses flash to play the audio, so if you have 
the flash plugin installed it should work.  Oh, check the system logs. 
You might need to toggle an selinux boolean to allow browser plugins 
network access (mozilla_plugin_can_network_connect).

Another one to try is Clementine.  It handles playlists and internet 
radio.  If it recognizes the title of a song in a stream it will even 
retrieve the lyrics.  Much better than rhythmbox all the way around.

With ISC's dhcpd, you make "architecture-type" a condition:

option architecture-type code 93 = unsigned integer 16;
if option architecture-type = 00:07 {
filename "shim.efi";
} else {
filename "pxelinux.0";
}

At least, I think that's what you mean.

Just so that we're clear, if you boot this computer using an older
version of GRUB2 from tftp, your custom application works, but if you
then use the newer version, it doesn't work?  You can reproduce both
the working and not-working conditions?

If so, what version was previously working?  It'll be easier to look
at differences in the build process if we have something specific to
look at.

I'm using grub2-efi-2.02-0.16.el7.centos, and it loads configuration
files with that style naming.  I was under the impression that it
always had.  Can you clarify what changed, and in what version?

Once you copy this link as described above just about any player should
take it

Rhythmbox is entered either
 File -> Playlist -> Load from file... -> listen.pls [or any other pls
file you have]  or...

If you "Copy link address", usually just below the save option, you can
Library -> Radio -> Add
which will self populate the copied url.  Hit return and enjoy the station.

VLC is similar with the copy url option...
  Media -> Open file -> listen.pls
  Media -> Open location from clipboard [hotkey= ctrl+v]

Parole Media player failed the open location option under Media with a
Gstreamer backend error but...
   Media -> Open -> listen.pls  [from the saved file]
work just fine.

I tested these with your link, nice station btw, and am just establishing a
pattern.  Look into your favorite app for listening and either open the
saved *.pls file or open link option and copy from clipboard.  Either way
works in most cases.  I download my list of favorite station on DI.fm and
others into a .pls file and this allows me to load all my stations at once
in Rhythmbox making recovery a breeze if I have to rebuild.  HTH.

You can save that link by right-clicking on the button and chosing
'Save Link As...'. Then feed the saved file (listen.pls) to mplayer
like this:

mplayer -playlist listen.pls

Next time you want to listen to it, you don't even need firefox
(assuming the link in list.pls doesn't change often).

I know this is not much help to you, but it works here (fully updated
Fedora 22). And I _think_ that Flash Player is not involved.

Yes, and gmail...  I thought this was answered quite some time ago.

You will have trouble getting a mail client to accept mail as being
not-junk when the mail comes with headers that say it is junk.  If you
were to circumvent that, all externally-determined junk mail is likely
to get passed through as not-junk.

You'd need to use a better mail client, that lets you set priorities of
what un-junks the spamminess rating.  So that certain list headers get a
very high rating.

Or, receive your list mail from a different address not served by yahoo
or gmail, while realising that choosing a different service that works
now, may inherit the same problem at some future time.

Really, a better way to handle mailing lists is a newsgroup server.  But
I'm less than impressed with the news clients I've tried on Linux, so
I've never bothered using the gmane news gateway.
