I haven't used it myself, but people use the screen program for such 
things

hm.. screen? I will look it up, haven't heard of this one ..

wow .. screen alows me tu have multiple sessions in one ssh window.. 
like in local linux .. I needed that badly !! ..

but I am not sure it's intended for what I described above .. basically 
running apps in background -- so they run (for days and weeks) after 
I close the ssh

You can use screen to detach a session and reconnect with it later, 
possibly from an entirely different machine

Another way is to have the program detach itself, possibly switching 
to running onder a different user account

Kaj , thanks .. it seems screen is very beneficial tool for working 
on ssh , I will start learning and using it

The link in Graham's article is good

yes, I am just reading it , it shows all these options .. Graham 
thanks

Yes, Janko, use screen.  That is what I did for my Tretbase DBMS 
awhile back.

I am using drach now and works very nice ... but screen is awesome 
tool to and I will use it in general sshing now (thanks Graham! I 
added dtrace sample to that wiki)

the command "nohup"  may still exist and be usefull

yes, nohup is very usefull too , with &  .. for example nohup some-longer-tast 
&  .. but for my concrete example I wasn't able to figure out why 
rebol script terminated after a while, not on every exit but at some 
point I just saw it wasn't running any more .. and by the look of 
nohup.out file there was no error .. but "rebol terminated"

tast = task

Janko, it's just that everytime I learn something that I know I will 
forget .. I write it in a wiki somewhere :)

the freely hosted mindtouch wiki that I use is convenient for things 
like that. ...

So, instead of storing the information in my head, I just store the 
pointer to it instead :))

funny  use altme for that  :-)  posting stuff to myself.

I use Carl's Rebodex.r  program with some minor modifications.

what I am missing is a synch with a server so I can always have the 
same info everywhere... which AltME works nice for as would the wiki.

Janko, basically the thing is, if you want to see the program's output, 
you need to use screen. This allows you to have output and detach 
it. Otherwise, you can just redirect the output to a file (or to 
/dev/null), then you can exit your ssh session without problems.

eg. rebol myscript.r </dev/null >/dev/null 2>&1 redirects everything.

i'm not sure if it's installed by default anymore, but there also 
used to be a "nohup" program which would redirect your program's 
io and detach it (run it in the background).

(which is basically equivalent to   rebol myscript.r </dev/null >somefile.log 
2>&1 &)

Graham: .. and it can also help others like in this case .. as I 
said above I have the wiki for exactly this thing linux commands 
because I use them just enough so I keep forgetting the more tricky 
ones http://www.manage-websites.com/doku.php?id=tutorial-linux-shell
<-- here they are

Gabriele: I was using nohup like this >> nohup /.../rebol script.r 
&  << but at 2 times rebol script got terminated for some reason 
after a while.. it did stay alive after I closed and reopened ssh 
but when I came later it wasn't running any more and by looking at 
output file nohup.out last thing was "rebol terminated" so it didn't 
 exit on error but got terminated in the same way if I press Ctrl+C 
(maybe I just need to read more about nohup)

now it works with dtach and it works ok so far

Janko, it's hard to say what could have sent a sigint or similar 
to the rebol process. you could though catch those signals from REBOL 
if you wanted, via the system port.

What distro works best with sdk-2706042.tar.gz "out of the box" (with 
regards to rebview and fonts)? I just need something I can quickly 
install under VirtualBox and do some basic cross-platform REBOL GUI 
development/testing ... without having to hack it to make it work.

Ashley, Ubuntu works fine .. you just have to specify the full path 
to any fonts you use if using AGG fonts.

I think I had to also change the default font used for RebGUI.

OK, so I've downloaded Ubuntu 9.04 (64bit) and got it running under 
VirtualBox, then I download and untar/zip the REBOL SDK and open 
a console session. cd to the REBOL dir and do a chmod +x and type 
./rebview ... which comes back with a "file or dir not found message" 
... anything else I need to do to get REBOL working? Oh, and what 
font looked best with RebGUI in your opinion?

If I remember correctly you have to install some 32-bit libraries 
to run Rebol on 64-bit Linux distros.

Uh, or use the Ubuntu 32bit distro instead?

This ML thread may help

http://www.rebol.org/ml-display-thread.r?m=rmlYJZC

Thanks, after reading that I think using the 32bit distro is the 
easiest solution.

It does sound like it. I have no problem running Core or View on 
Ubuntu 32-bit but I've only just moved to 8.10 from 8.04

23-Jun-2008 Got BROWSE to work on Rebol/View 2.7.6.4.2
	Used strace to see what files rebol does
		strace -o strace-output ./rebview2.7.006.4.2
	Rebol looks for:
		/usr/bin/netscape
		/home/anton/.netscape/preferences.js
		/home/anton/.netscape/lock
	None of which exists, so..
	Created symbolic link "netscape" pointing to "firefox"
		cd /usr/bin
		sudo ln -s firefox netscape
	The above did not help.
		>> browse "google.com"
		sh: Syntax error: Unterminated quoted string
	This does though!
		>> browse "http://google.com^(22)"
	Maybe I don't need the symbolic link?
	Remove the symbolic link.
		sudo rm /usr/bin/netscape
	Rebol does not like that !
		>> browse "http://google.com^(22)"
		sh: /usr/bin/netscape: not found
	Restored the link.
		sudo ln -s /usr/bin/firefox /usr/bin/netscape

I am using Ultimate Extreme-a custom Ubuntu-under VmPlayer and installed 
View. It works fine. Then I emailed my license and put it in the 
root of .rebol but when I start View it does not see the license 
? Ideas ? Thanks !

why do you need a license for rebol?

Well for Linux, not really but Windows,yes. Just wondering why it 
does not show as registered on Ubuntu ?

Ashley, normally Ubuntu has the 32bit libs installed by default - 
REBOL worked out of the box for me here.

In any case, it's easier to do a "sudo apt-get install ia32-libs" 
than do a new installation, no? :)

OK, I've got it running under a clean install of Ubuntu 32bit. Now, 
how do I determine what scaleable fonts REBOL can actually use? (%/usr/share/fonts/truetype/freefont/ 
doesn't seem to have all that many ... and they look pretty ordinary 
atsize: 72).

Are you talking about AGG or standard View text? For the latter, 
anything that X can use REBOL can use, in principle at least. For 
the former, I think any TTF file will work (notice that you can install 
the MS Core Fonts package).

The later. Windows fonts are easy enough to find (c:\windows\fonts) 
as are Mac (/System/Library/Fonts & /Library/Fonts) ... I was hoping 
there was a simple "they're located here" equivalent for X11-based 
*nix.

if you add fonts I believe you have to rebuild the font map ie. fonts 
can be scattered over different directories.

All I want is a simple way of finding out what fonts REBOL can access 
on a clean install of Ubuntu.
