How to open an OpenOffice document and scroll to a bookmark?
You will likely need to look into the OpenOffice scripting
facilities. Look at some of the OpenOffice Macro
Information by Andrew Pitonyak. In his document "Useful
Macro Information" (.odt file link warning) pay attention to
section 7.2.3 "You can move a cursor to a Bookmark anchor"
Dim oAnchor 'Bookmark anchor
Dim oCursor 'Cursor at the left most range.
Dim oMarks
oMarks = ThisComponent.getBookmarks()
oAnchor = oMarks.getByName("MyMark").getAnchor()
oCursor = ThisComponent.getCurrentController().getViewCursor()
oCursor.gotoRange(oAnchor, False)

How do you connect to a remote linux server (graphically) with Open Text Exceed
If I recall correctly, Exceed is a generic X11 server for
Windows.
The usual way to use X11 over the network is by forwarding it
over SSH, the secure shell protocol. Most SSH clients support X11
forwarding; this includes PuTTY (Connection - SSH - X11)
and SecureCRT. First ensure that the X11 server (Exceed) is
running, then enable X11 forwarding in the SSH client, connect to
the remote machine, and run your program.
The older, less secure way is to allow X11 connections to be made
directly from the remote machine; again, connect over SSH, but
set the $DISPLAY environment variable to your IP
address followed by a : and the display number
(usually zero). This obviously requires mucking with port
forwarding (TCP ports starting with 6000 at display 0), and is
much less secure.

Map open port to process
You can do netstat -tulpn and grep for the name of
the port.
For instance, using your example port, the command would be
netstat -tulpn | grep 10101

MacOS 'open'-command for GNU/Linux
No, Linux is too configurable for that, on OSX you start off with
Safari, the OSX File Manager, etc, but on my laptop right now I
don't even have graphical and I work purely in TTY, to get an
open command on Linux to work it would need to be told how to
handle every file, which at that point I might as well just make
my own.
#!/bin/bash
if [ -d $1 ]; then #Check if $1 is a directory
nautilus $1 #To be honest pcmanf is way better
fi
if [ -f $1 ]; then #Check if $1 is a file
if [ $1 == *.txt ]; then #Is the extension .txt?
gedit $1
fi
fi
I personally prefer to alias the file extensions, so I can just
type to path to the file and it will open it, decompress it,
compile it, etc, it's one of the better features of ZSH, I
recommend you try it.
description
openvt
will find the first available VT, and run on it the given
command with the given command options,
standard input, output and error are directed to that
terminal. The current search path ($PATH) is used to find
the requested command. If no command is specified then the
environment variable $SHELL is used.
OPTIONS
-c, --console=VTNUMBER
Use the given VT number and not
the first available. Note you must have write access to the
supplied VT for this to work;
-f,
--force
Force opening a VT without
checking whether it is already in use;
-e,
--exec
Directly execute the given
command, without forking. This option is meant for use in
/etc/inittab. If you want to use this feature in
another context, be aware that openvt has to be a
session leader in order for -e to work. See
setsid(2) or setsid(1) on how to achieve
this.
-s,
--switch
Switch to the new VT when
starting the command. The VT of the new command will be made
the new current VT;
-u,
--user
Figure out the owner of the
current VT, and run login as that user. Suitable to be
called by init. Shouldn’t be used with -c or
-l;
-l,
--login
Make the command a login shell.
A - is prepended to the name of the command to be
executed;
-v,
--verbose
Be a bit more verbose;
-w,
--wait
wait for command to complete.
If -w and -s are used together then
openvt will switch back to the controlling terminal
when the command completes;
-V,
--version
print program version and
exit;
-h,
--help
show this text and exit.
--
end of options to openvt.
note
If openvt is compiled with a getopt_long() and you wish to
set options to the command to be run, then you must supply the
end of options -- flag before the command.
history
Earlier,
openvt was called open. It was written by Jon
Tombs <jon[:at:]gtex02.us[:dot:]es or jon[:at:]robots.ox.ac[:dot:]uk>. The
-w idea is from "sam".
