Ubuntu: what command is it?

Hi,

1) I have a linux Ubuntu 10.04.3 workstation
2) It gets the IP address from DHCP server
3) I am installing a Lotus Notes' program; but this is nothing to do with the lotus notes
4) I am confused with one of the linux command as specified in step # 3
5) To install the above program, i follow this reference:
http://blog.turabdin.nl/2010/08/install-ibm-lotus-notes-8-5-2-on-ubuntu-10-04-64-bits/

6) The summary is as the followings:
Step 1: First install the dependencies:
sudo aptitude install libgnomeprint2.2-0 libgnomeprintui2.2-0

Note: I follow this command; and it is executed successfully (I do not have error message)

Step2: After that install the DEBs with –force-architecture switch. No need to force everything.
sudo dpkg -i --force-architecture ibm-lotus-notes-8.5.2.i586.deb

Note: As I put the "ibm-lotus-notes-8.5.2.i586.deb in the Desktop; I modify a little bit the above command; It is executed like this:
sudo dpkg -i --force-architecture Desktop/ibm-lotus-notes-8.5.2.i586.deb
The Result: It is good; it is also executed successfully (I do not have error message)

Step3: That’s it, start the client running.
/opt/ibm/lotus/notes/framework/../notes

Note:
- This is the command that I get confused!!!
-What command is it?
- Is it Change Directory ("CD") or what?
- Is it a statement " /opt/ibm/lotus/notes/framework/../notes " or what?

- If I am at [root@localhost init.d]#, and i type in: ./network restart (I know that I ask the network to restart)
- If I execute " nano /etc/sysconfig/networking/devices/ifcfg-eth0 " (I know that I am doing the network configuration)

- But this --> " /opt/ibm/lotus/notes/framework/../notes " : I do not understand

7) This is not a lotus notes' thing; but it is a linux thing
8) Would you somebody explain the above command please?
- I have successfully executed Step#1 and Step#2
- I need to know what should I do at the Step#3?
- Any help?

9) Thanks

tjie

Its simply a link to the file, you can remove the /.. part and just run it like this:

/opt/ibm/lotus/notes/framework/notes

that runs the "notes" application installed with lotus

I don't know lotus notes, but as far as the syntex of the command on step 3 it is a command.  Specifically "run executable at this location".

I believe ".." refers to the full install path.

You might want to 'cd' down the path to see what is there.  Once you drill down you should be able to type 'notes' (or ./notes in the event that you don't have your environment set up with current in the search path).

/opt/ibm/lotus/notes/framework  <-- this is the directory the file is stored in

notes is the application's binary name

Enter the command as it's typed. It refers to an executable file called "notes" in specific directory.

Yes, if you type that into a terminal (like the others) it will work.

> /opt/ibm/lotus/notes/framework/../notes
where ".." is parent directory (one directory up)
so it is equivalent to
/opt/ibm/lotus/notes/notes

In other words,
cd /opt/ibm/lotus/notes/framework/../
is the same as
cd /opt/ibm/lotus/notes/

But the problems that i have now are:

1) I execute the following command:
cd /opt/ibm/lotus/notes/framework

2) Then, I type in: ls
- It will appear 4 items:
eclipse  license  rcp  shared

3) I want to know under "eclipse"
- ls
- and it appears "diho"

4) under "license"
- It appears "src"

5) under "shared"
- it appears "eclipse"
- under this "eclipse", it appears "features" and "plugins"

5) It seems I could not find "notes" after the framework

6) Do you think it is "hidden files"?

By the way: it's exactly the same in the Windows command prompt (except for the slash -> backslash)

Have to wonder why they chose to use the \..\ instead of just using the real path.....

In my original post I knew the command as documented would result in going back to the parent folder -- but didn't even think about a case where they actually meant it that way!

thie -- what happend when you typed the command exactly as specified?

I assume that the path up to and including framework is a fixed path in some setup-script, which can be redefined by the person installing the software., and that ../notes is relative to that pixed path. Plausible enough I hope...
