Linux Servers Support / ftp between computers

« Last post by fullofhope on November 20, 2012, 04:19:30 PM »

Hi,
A very elementary problem but I cannot solve it after many days.
Two computers. Both in same room. One on my left, one on my right. Both ethernetted to the box on the wall. Both use PCLinux. Both have firewall turned off. I don't give a toss about 'security' I just want them to talk to each other.
I can just about get an ftp connection (on a good day) on Krusader. I want to use this to be able to synchronise the two computers. Both have multiple HD's and multiple partitions by the way. I can type the following on the left:

ftp://myname@192.168.1.xx

--and that gets me into my home directory on the right OK. But I don't always want my home directory, but a different partition called, lets say, /media/Slideshows. Much too big to have in my home directory, that's why it has its own partition.

Now there is undoubtedly some easy way to type in some different command that will get me straight into where I want it to be. I can't find simple advice about this anywhere, because it is too elementary (except to me of course). Please someone enlighten me!

Below is something I needed help with, it is something similar to what I had gotten some help on

case and switch script should:
-request a user name,
-request 8 numbers and ask the user if they are to be added or sorted (both need to
work!) OR request 8 names (1
st
and last) and sort them by the second field (check
the hints and tips sheet for multi part user input),
-multiply two numbers from user input,
- give the user the choice of running; ‘who’, ‘w’ or ‘finger’ and echo only the first
and third columns to the screen (save this also for exit echo),
- have a conditional ‘while’ statement,
- track the number of choices the users makes (use a counter),
- have at least 2 if statements,
- include an option that will add from a start number and end at another number
using user input for all numbers including the increment number

I made a small error I had included 2 separate script statements thinking they were all one, the 2nd was in C-shell and did not not that. So I will post the one only for help and what i've done so far. I am getting an undefined variable, it brings up he date I want but the variable error shows and it is because of line 5. Also below what I have done so far is the script I am trying to alter into a working script, let me stress this is not a test or anything just I have been having to deal with a future mother in law and father in law that were hospitalized a week apart so I fell behind on a little of my work so I am desperate for help.

Ty,

Chris

I thankfully was able to actually work out the answers for the questions I needed help on. But if anyone can please help me with the linux shell scripting post that I made it would really bail me out of a bad mess. I just can't grasp the concept of building scripts by myself.

First let me apologize for the posting I am asking for help for this one time, I have had to deal with my future mother in law and father in law almost passing away on us and it led me to fall behind a little. I have also been sick with the flu, so if anyone can please help me with this, i would be grateful. I certainly will still pose a question or 2 in the future but this would be the only time i'd ask for this much help. With my frame of mind trying to understand how to put together this long script is very hard for me, i'm trying to research it and figure it out but I have till Monday and not sure I can do it.

Ty,

Chris

Linux Development & Programming / Shell Scripting Help

« Last post by Chris4610 on November 09, 2012, 04:18:02 AM »

Hello Everyone,

I am looking for help in figuring out exactly what I need to do and if someone can help me figure it out, it would get me out of a huge jam. I am including what i'm being asked to do and will show an example I was given, I was told that the example could be altered to do what is asked below, I just don't understand this script stuff at all.

Ty,

Chris

Case – switch 2, 9 points (3 if it runs correctly, 5 if all components are included and 1 for
comments) and yes we live in a partial credit world.
This project is an extension of the case and switch assignment from last week. We have
used all the elements of this script in prior homework projects, puzzles and/or scripts.
This time around everything is a choice in a case switch script.
Your shell script will use case and switch and should include the following elements:
some kind of conditional test to proceed (date, verify users is logged, etc)
request the user’s name (save as a variable to be used at exit)
a counter that counts the number of total choices made by the user
a use of the cut command (cut a field from you friends list or some other file)
an option to run 5 different commands (ls, who, ping etc) and
on exiting the script, echo the user’s name, user inputs (you will want to save
these as varialbes and how many choices the user made).
Comments MUST be included in the script! Your script should be easy for anyone to run
without the need of prompting from you, the developer.
Email a copy and leave an executable copy in the appropriate homework directory.
Remember, by reading your comments I should be able to see exactly what your script is
doing (or suppose to do). Why use comments? Comments force you to think through the
scripting process. Scripting could be considered a mechanical process of converting your
comments into UNIX commands.
*** READ the following paragraph to help you with your puzzle!!
Trouble shooting your script (in case you need it)…. This script has more elements and
more potential to bonk, crash, not work. What you should do is start with the BASIC C-S
script and start adding elements to the known to work script. If the script bonks and
before you declare yourself “lost”(remember lost is a television show!), comment out newly
added lines until the script works again. Now you have a block of code that needs to be
carefully reviewed. If we were sitting in a face-to-face class this is exactly the process we
[YOU] would be asked to do. Start with a simple script (the frame work from last week is
a good starting point) and develop it from there, don’t forget to make copies of your work
along the way!!
