General :: Explanation Of Here Scripts As Well As The "cat" Command
Aug 13, 2011
I am currently in the very early stages of learning how to use the shell and write scripts (and I mean really early- only been at it for 3 days or so). Now I am following a tutorial, and I have reached a section about the so-called "here scripts" or "here documents".
[Code]...
Now what I don't understand is how those two scripts, once run, produce the same output.. I believe this is because I don't understand the "cat"-command (which is not quite useful, considering it seems to be a very practical and widely used command).
So would anyone care to explain to me what it does in this specific script as well as alternative applications? (And please refrain from just quoting the man-pages.. I have read them multiple times, and I still just don't get it - It's probably very simple,

I'm trying to learn to rename files with the command line, and after browsing around a lot of pages I finally found a command that uppercases the first letter of a file, but the problem is that I want to understand the meaning of each command. The command is:
for i in *; do new=`echo "$i" | sed -e 's/^./U&/'`; mv "$i" "$new";done
I understand the 'for' kinda... but not the 'echo' or '`' and especially the sed command.

Back when I was first learning Linux, one of the questions that I kept wondering about was "what are all these files and directories for?" I couldn't find a resource that would explain them in a digestible manner. Specifically, I was looking for one that would allow me to look at a Linux filesystem interactively, collapsing and expanding folders to look at just the ones I was interested in at the moment. So later, when I got the opportunity, I wrote it.
But despite a ton of research, I'm still not totally knowledgeable on the subject. The most important thing I'm looking for right now is for experienced Linux/Unix people to tell me where I got stuff wrong, and for newbies to tell me how useful it is to them and which things need clarification. I'm also interested in technical and graphical ways to improve usability, like better icons, layout, etc. I know I need to be able to collapse long descriptions, but what would you like to see? The Works Cited list and a full introduction are still on the way as of this writing.
Without further ado: Linux Filesystem Hierarchy Explanation. You'll need a fairly recent browser that can handle XSLT; the actual info is stored as XML, and transformed into HTML with an XSLT stylesheet. This is still a work in progress, and I'll be updating it as the thread progresses.
Finally, would people be interested in collaborating with me on this, as an open-source project? I've never done anything like that, and I'm not sure how much time I'll be able to give it in the future, but I really think this should be continued and expanded.
Edit: Works Cited and decent intro are now in place.

My family have three Linux operated ACER ONE netbooks, all of them need the new Firefox 3.6 download as the old format wont be supported supposedly by ..... etc. I have downloaded the SOFTWARE but cant get it to run, the Firefox explanation mentions lots of files etc that are cant access, nor can I excecute any files once they have been extracted. The same happens with any software but Iv ignored it till now, not having a "modern" browser will make things difficult. I need it explaining simply. On another subject can anyone use facebook chat on Linux

So I was trying to remotely access my XP laptop from my Ubuntu laptop. I read up on tsclient and rdesktop and tried both methods. For example, in the terminal, I typed:
rdesktop <host ip>
However, this came back with the following error:
autoselected keyboard map en-us.
ERROR: <host ip>: unable to connect.
After a bit of internet searching, I found the solution to the keyboard problem. I typed:
rdesktop -k en-us <host ip>
This yielded the following error:
ERROR: <host ip>: unable to connect.
No clarification, no explanation. nothing. Does anyone have any ideas?

I know my way around MS Windows much better, but I just don't feel right trying to program something for Android on a Microsoft operating system. I am interested in Android programming so I followed the instructions on [URL] to install the environment on my computer...
I just installed the JDK, SDK, Eclipse successfully (or I assume):
* When I get to Step 4 where I'm supposed to run 'android' it will not run. I get the error message "android: command not found" (I am definitely in the right directory).
** When I double-click it in nautilus, it opens up in gedit. I can set the permissions in nautilus (through the properties - Allow executing file as a program) and get it to work,
My system:
Intel i7
Ubuntu 10.10 Maverick Meerkat
android-sdk-linux-x86
eclipse 3.6.2

I want to be able to use Ctrl+R to have reverse-i search. Also if I press Shift+Up Arrow after typing the first few characters of a recently executed command then the shell should complete the command by finding the most recent commmand having the same first few characters.

Bash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?

When you run the following cp command in the BASH terminal, how does Linux know which files are the source and which are the destination when copying multiple files from one location to another?How does Linux know that the services, motd, fstab, and hosts files are the source and the /home/fred/my_dir is the destination?This question came up in a Linux class and I was not sure of the answer. I was thinking it is based on the source path entered ending with a file path and the destination being a directory, but was not sure.

i'm trying to redirect the output of a command to the input of the next command. not sure if i'm going about this the right way. an easy method would be just to store the output of the previous command in a file and redirect input to read that file, but i'm curious to see if this can be done without writing to any files.

Up until now I've been using plink to remotely compile a project I'm working on. But recently the administrator from the remote server updated the distribution and messed up some configurations. My project has a lot of scripts written for tc shell (tcsh), and now the default shell is bash. There is no way to change this. Another problem is that now I need to run newgrp to change my default user group.
So... to work around this problem I've changed my .bashrc to run newgrp and then tcsh. If I do a normal connection using SSH, everything works as expected, but when using plink, or SSH to remotely execute commands, the shell gets stuck on the newgrp command. I think it's because both applications need a return value from newgrp to send the command I need to execute. Remotely running scripts that call a shell also get stuck like newgrp (newgrp also opens a new shell and that's why it gets stuck) my .bashrc is as follows:
Code:
user_grp=`id -g`
if [ $user_grp != 4919 ]; then
newgrp new_group_id
else
[code]....

I want to scan a particular directory recursively and run a particular command with each file as input. For this I am using "find /dir/path". I dont want to write any long script containing loop on the output of "find". I want a single command which will allow me to run a command on each file of the "find" command output.
