Do you need help?X

Why not use Perl?



$ perl -p0e '$_=~s/(.)\n(.)/$1 $2/g' < 1.txt
This is a test file, what I am trying to do is get the lines to join.



It isn't a complicated thing, but I also want to keep the paragraphs separate.



$ perl -p0e '$_=~s/(.)\n(.|\n)/$1 $2/g;$_=~s/ \n/\n/g' < 1.txt
This is a test file, what I am trying to do is get the lines to join.
It isn't a complicated thing, but I also want to keep the paragraphs separate.

Backports.org might have a version of evince that isn't dependent upon 
all of Gnome.

Must have been something in Sarge.  You're right, I've got a beep again

88 watts it used to be. A modern desktop PC will consume several hundred watts of power, which is as much as it takes to make a room "quite hot" -- do you think you could get your room hot by leaving the lights on?

It might be worthwile to measure power consumption again, with modern equipment -- you'll bes surprised.

Single quotes go around the whole sed script unless you are using a
separate sed script file.
try      sed 's/\n//' 1.txt > 2.txt

This command erases all line breaks
sed -e :a -e '$!N;s/\n/ /;ta' -e 'P;D'
although you have to adapt it to not delete paragraphs. Using regex, the
line would then become something like
sed -e :a -e '$!N;s/\n[^\n]/ /;ta' -e 'P;D'
Good luck.

There is no thermal shock on power-on. What is most likely to fail is the PSU (happened to me once).

Thanks, Florian,

Its too much like work to get Gnome to do anything useful.  I've purged
the lot.  I'll stick with xpdf and kpdf.

I know your sentence continues along a different line, but let me just interject here that computers have never consumed as much energy as they do today. True, energy consumption per CPU instruction has gone down dramatically, but that is far outcompensated by the increase in total computing power.

"$" is a special character to make, so in cases where you need make to
pass an actual "$" to something else, you have to use the special
variable "$$".

In this case, "d" is a shell variable defined within a rule.  The
shell refers to it as "$d", but using "$d" in your makefile would
cause make to look for one of its own variables named "d".  "$$d"
becomes a literal "$d" to make, which is then passed to sh.
"$(addprefix ...)" is a make command, and "${SYMLINKDIR}" and
"${SYMLINKTARGET}" are makefile variables, which will be expanded by
make and passed to the shell as literals.

The difference in this example is that find is being run, and its
stdout returned as a string.  The shell pattern is "$(command)", which
is equivalent to "`command`".  Again, since the "$" is relevant to the
shell, not make, we have to use the special "$$".

Hopefully this example is clearer now.

It's defined locally to the for loop (well, not *really* locally, but
effectively).  Any name that isn't already being used should be fine
here.  Not knowing what the context around that snippet is, I couldn't
say if "bn" was chosen for some mnemonic reason.

google has made a nice survey on thousands of HDs for some years. They
measured the effect of temperature and time on the failure rate. Don't
have the link handy but do check for it. It will give you the answers
you need regarding your HD

other factors are WAY MORE important than the amount of time you're on

it is but if you find a lot of other reasons to keep it alive then you
probably want to check ways to minimize power consumption. Automatic
adjustment of CPU frequency,  automaticaly powering off HDs and
monitor when not in use, funs wich adjust RPM according to temperature
etc

Aha! I do 'echo -e "\a"'

If I run your file through fmt, I get
<output>
This is a test file, what I am trying to do is get the lines to join.

It isn't a complicated thing, but I also want to keep the paragraphs
separate.
</output>

Of course, that may not have been what you were looking for, but I
just thought some might find it useful later.

Message-ID: <46D596BD.1070405@ccf.auth.gr>
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit

One very annoying thing that happens with icedove (1.5.0.12) on Debian
Lenny, is that when I get an email with a pdf attachment, I double click
on the attachment and I get the well known window which says:

You have chosen to open

mplahmplah.pdf

which is a: BIN file
from imap://....

What should icedove do with this file?
Open with "kghostview (default)"
Save to Disk

Do this automatically for files like this from now on. (GREYED OUT)

------------

First of all, I do not understand why it offers to open it with
kghostview (which I hate). Where could I change this option? In advanced
configuration -> Config Editor, I can't find any option which has to do
with pdf files...

And this would not be such a problem if the option to remember the
program for pdf files which I choose and use it from now on, was not
greyed out and thus unusable...

Which brings me to my last question: I don't have a ~/.icedove nor a
~/.thunderbird directory... Where does it store my profile?

Do you have any other x-terminal-emulator installed?  I tried in
xfce-terminal and it doesn't beep.  Perhaps there's an xset setting to
allow audible beeps.  Look at the xset man page, especially the -b
option.

Unfortunatly for you, the computer that I'm directly attached to me is
on the floor below (monitor, keyboard, and mouse cables run through the
floor) so I can only hear the beep if the room is quiet.  It is noisy
right now.  Perhaps you will have some luck.

You could try the GUI interface to xset; something like gtkxset or
gxset.

Well, it depends what you call a modern computer. Yes, i know that
they have PSUs with 350 and 400 watts, but they are usually not loaded
completely. What i had tested was my previous PC with Athlon XP 1600+
- that's not so old.

About making room hot - in summer few electric devices can really make
my room noticeably warmer. It's because of bad ventilation, and
massive walls.. usually my room is cooler than outside. And i noticed
this by using the same Athlon XP 1600+ which i measured.

I will try to make measurements for my new Athlon 64 5000+

Regards,
Atis

well that somehow makes me feel better, 'cause I was starting to feel

I'm trying the link you provided with the command

mplayer 
"rtsp://rmv8.bbc.net.uk/radio2/fridaymusic.ra?BBC-UID=a426cbda207670378b86528c714caba3684a2b4fc040b101329203b36444a5b5&SSO2-UID='" 
-vo null -vc null -ao pcm:file=/mnt/appo/musica/webber.wav

and it seems to work fine! :-)

by the way, isn't there a way to record directly in mp3 I suppose?

Later I'll try with epiphany too... but why are you saying that it is 
due to a broken install of epiphany?

thanks!
