Ed at Linux command prompt

Dear All,
I was trying to use ed command to open an editor to update my sql statements on Linux. Please can anyone tell me how I can implement it in Linux command prompt.
Thanks in advance,
Ash

$ ed /etc/hosts
632
5
192.168.1.45 srv001 loghost
s/g/cal
192.168.1.45 srv001 localhost
w hosts
634
q
$ ed at command prompt just works fine. What's your issue? And how is it related to sqlplus?
Do you want to default it to vi?
$ sqlplus /
SQL> def _editor=vi(vi is an editor available on Unix. On Linux, you can get the source on http://ex-vi.sourceforge.net . If you are really lazy you can use the vi clone your linux distribution provides)
If you want to change the default, check for solutions with login.sql/glogin.sql in the doc/forum

OTD Developer Days-Getting a Command prompt in the Linux Shell for DD

Hi,
I've loaded the Virtual Machine (and all the files for Developer Days) and can launch the virtual machine from Windows 7...I get as far as the Linux shell showing that OTN Developer days is [running] in the VM, but I get no command prompt to login in..How do I a command prompt in this Linux shell? (thanks...I know this is a novice question..)
Best Regards,
Dave

On many UNIX systems there's a utility called detach which will launch the following command in such a manner that killing the shell will not kill the process. On systems that lack this command, I'd find an open source implementation and install it.

How can I pass a value to the command prompt?

I was wondering how can I pass a value to the command prompt with Windows and Linux? I'm more interested in Linux's system than Windows though. Is there a way to return info from the command prompt?

Here is a snippet from http://mindprod.com/jglossexec.html that explains how in detail.
Runtime.getRuntime().exec("myprog.exe") will spawn an external process that runs in parallel with the Java execution. In Windows 95/98/ME/NT/2000/XP, you must use an explicit *.exe or *.com extension on the parameter. It is also best to fully qualify those names so that the system executable search path is irrelevant, and so you don't pick up some stray program off the path with the same name.
To run a *.BAT, *.CMD, *.html *.BTM or URL you must invoke the command processor with these as a parameter. These extensions are not first class executables in Windows. They are input data for the command processor. You must also invoke the command processor when you want to use the < > | piping options, Here's how, presuming you are not interested in looking at the output:
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat" );
Runtime.getRuntime( ).exec ("cmd.exe /E:1900 /C MyCmd.cmd" );
Runtime.getRuntime( ).exec ("C:\\4DOS601\\4DOS.COM /E:1900 /C MyBtm.btm" );
Runtime.getRuntime( ).exec ("D:\\4NT301\\4NT.EXE /E:1900 /C MyBtm.btm" );
There are also overloaded forms of exec(),
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat", null);
Runtime.getRuntime( ).exec ("command.com /E:1900 /C MyBat.bat", null, "C:\\SomeDirectory");
The second argument can be a String [], and can be used to set environment variables. In the second case, "C:\\SomeDirectory" specifies a directory for the process to start in. If, for instance, your process saves files to disk, then this form allows you to specify which directory they will be saved in.
Windows and NT will let you feed a URL string to the command processor and it will find a browser, launch the browser, and render the page, e.g.
Runtime.getRuntime( ).exec ("command.com http://mindprod.com/projects.html" );
Another lower level approach that does not require extension associations to be quite as well set up is:
Runtime.getRuntime( ).exec ("rundll32 url.dll,FileProtocolHandler http://mindprod.com/projects.html" );
Note that a URL is not the same thing as a file name. You can point your browser at a local file with something like this: file://localhost/E:/mindprod/jgloss.html or file:///E|/mindprod/jgloss.html.
Composing just the right platform-specific command to launch browser and feed it a URL to display can be frustrating. You can use the BrowserLauncher package to do that for you.
Note that
rundll32.exe url.dll,FileProtocolHandler file:///E|/mindprod/jgloss.html
won't work on the command line because | is reserved as the piping operator, though it will work as an exec parameter passed directly to the rundll32.exe executable.
With explicit extensions and appropriately set up associations in Windows 95/98/ME/NT/2000/XP you can often bypass the command processor and invoke the file directly, even *.bat.
Similarly, for Unix/Linux you must spawn the program that can process the script, e.g. bash. However, you can run scripts directly with exec if you do two things:
Start the script with #!bash or whatever the interpreter's name is.
Mark the script file itself with the executable attribute.
Alternatively start the script interpreter, e.g.
Runtime.getRuntime( ).exec (new String[]{"/bin/sh", "-c", "echo $SHELL"}";

Running a GUI application without holding command prompt

Hi there ,
I have developed a GUI application using Swing. After compiling the same successfully , when I run the same , presently , I am running it like ,
c:\> java xxx
where c:\ is the general command prompt on a Windows machine where I can type in my commands like javac or java and xxx is the class file name . Now till I complete using my GUI application and exit from the same , the command prompt will also be there ( and probably displaying the output of my System.out.println ) . So , two sessions are running , one is just the command prompt and another is the actual GUI application.
How can I avoide this ? e.g. when I type command "notepad" and press enter , notepad is started and the command prompt returns after starting notepad i.e. the notepad and the command prompt are not related now , I can close the command intrepreter and still notepad is running . What should I do to create such a Java GUI application ? Please advice .

If I understand you correctly this is something that happens in linux also. And I believe that you can solve this by creating to shortcut to this program.
And the shortcut or link to application will be the command line that you use to run the Java Application.
i.e.
java c:\javadir\subjavadir\application.class
And I believe that this will allow it to run without the command prompt. Just showing the GUI and no additional command prompt window. Freeing the command prompt is something that I don't know how to do in either OS.
I use the Link To Application method because I ultimately don't need to have multiple windows for one application. Even though it is nice to be able to kill the Application by destroying the command-prompt session (in case your app causes lock-ups during testing).
Post your results . . . I'm not even sure that I'm being clear at all with my explanation to your question.

Is it possible to run a java program without using the command prompt?

Hi,
I was wondering whether it is possible to run a Java program (not an applet) without using a command line in the command prompt?
Basically I want to run a program that will be continually running in the background and hence I don't want to have a command prompt screen loaded up as well - I just want the program to be running in the task bar.
I know how to run the program in the task bar - but I still need to launch the program from the command prompt - is there anyway I can get a program running without having to start it from the command prompt?
Cheers

Or create a desktop shortcut (in Windows) or an application launcher ( in Linux GUI).

How to Get Input from Command Prompt?

How can i get input from command prompt like
C:\
or linux ?
(Here's what I use now)
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String line;
Whlie((line=in.readLine())!= null)
{ System.out.prinln( line) ; }
IS THERE A BETTER WAY?

The main method within a java class accepts command line input through a String array.
In this example args is the String array. You can access the parameters as args[0] for the first parameter, args[1] for the second parameter, etc....
The usage for the example below would be :
c:\EDIFormat file1 file2
Where args[0] would equal file1 and args[1] would equal file2.
public class EDIFormat {
public static void main(String[] args) {
          if (args.length < 0) {
               System.out.println("No Parameters supplied. Exiting....");
               // open input and output files
               EDIFiles(args[0], args[1]);
Hope that helps!

Setting the command prompt...

Can anyone tell me what I would use to set the command prompt?
On HP-UX, I would reset the PS1 variable...
i.e. PS1="
\$ID @ \$HOST | \$PWD
--> "
On Linux, I would reset it as follows:
i.e. PS1="
\u @ \h | \W
--> "
Neither of these seems to work here...
I tried the following, and it give me the correct visual layout, but the values don't change when you change directories:
i.e. PS1="
`whoami` @ `uname -n` | `pwd`
--> "
Any help would be greatly appreciated...

Hi,
Changing Your Command Prompt
The syntax you use to change your command prompt depends on whether you are using the Bourne,
Korn or C shell.
Bourne and Korn Shells
For the Bourne or Korn shells, you redefine your command prompt with the PS1 command. The
following are three examples:
PS1=": "
PS1="`hostname`: "
PS1="`hostname`{`id`}}: "
The first example sets the prompt to a colon (:), followed by a space.
The second example creates a prompt consisting of your machine name followed by a colon and a
space.
The third example sets the prompt to your machine name, followed by your login name in braces
{}, a colon, and a space.
Type any of the examples above to change your current command prompt. The prompt will remain until
you change it again, or logout.
If you want to make your changes more permanent, add one of the above examples (or a prompt of your
own creation) to your .profile file. If you do this, the prompt you specify will appear each time you
login in or start a new shell.
C Shell
For the C shell, you personalize your command prompt with the set prompt command. The following
are three examples:
set prompt="% "
set prompt="`hostname`\!: "
set prompt="`hostname`{`id`}}: "
The first example sets the prompt to the percent sign, followed by a space.
The second example creates a prompt consisting of your machine name followed by the history
number of the command (hostname1, hostname2, hostname3, and so on).
The third example sets the prompt to your machine name, followed by your login name in braces, a
colon, and a space.
Type any of the examples above to change your current command prompt. The prompt will remain until
you change it again, or logout.
If you want to make your changes more permanent, add one of the above examples (or a prompt of your
own creation) to your .cshrc file. If you do this, the prompt you specify will appear each time you login
in or start a new shell.
Revert back.
Thanks.

Problem in executing Linux command from Java Programme.

hi everybody,
can anybody help me to solve one problem i have.
i want to capture the output of linux command "grep" in my java programme.but it is not working properly .(maybe this sub-process doesn't have permission to read files)
here is my code and corresponding outputs.
import java.io.*;
public class BSearch
public static void main(String kj[])
try
Runtime rt=Runtime.getRuntime();
String command="grep \"hello\" -r /usr/MyDir ";
Process rtProc=rt.exec(command);
InputStream is=rtProc.getInputStream();
BufferedReader br =new BufferedReader(new InputStreamReader(is));
String line =null;
while((line=br.readLine()) != null)
System.out.println(br.readLine());
br.close();
catch(Exception e)
System.err.println("Error in command "+e);
it finds "hello" pattern only in BSearch.class file although if i fire this command on LINUX prompt it
shows all the files in /usr/MyDir which contain "hello" pattern.
java programme output :
Binary file /usr/MyDir/BSearch.class matches.
linux command output :
/usr/MyDir/one.txt: hello sdfs
Binary file /usr/MyDir/BSearch.class matches.
/usr/MyDir/two.txt: kjsdf hello sdfsdf
will anybody help me solve this problem.

Oracle BPEL interactive installation in command prompt

Hi All,
I'm trying to install Oracle BPEL Process Manager for OC4J in linux environment at remote.I login to the remote machine through SSH.
I would like to know if there is any guide to install through command line. I mean interactive installer in command prompt, not the silent installation
I know it can be done by 2 ways:
1. Initiating the runInstaller by setting DISPLAY variable and having X-Client running on local machine.
2. Silent Installation.
Can I do interactive installation through command prompt?
Regards
Jude.

Hi,
for first check the relase version for your OS and instead of SLES10 make there SuSe-9.
And set your DISPLAY .

Reading states of usb-6501 kit from command prompt?

Hi all!
I have been planning to use USB-6501 kit as one part of my test bench.
There will be need of checking state of some relays on
tested unit.
I would like to connect 6501 to those relays and read those
states using bare command prompt commands like readDigPort.exe
1. What software in need to install minimum to use writeDigPort.exe or readDigPort.exe commands at command prompt??
Those commands should be included in python script.
2. Is there such Linux commands also included somewhere in installation media/net ?
I am Using Fedora 3 ( Comedi not supporting 6501 ?)
3. I need only easy way to set and read values from 6501 ports which are my possibilities to do it?
Thank you!

String draw size, in a linux command environment

I need to get the string length as it displays on screen (for image generation). First i did this through a simple php script but i discovered that the standard method in php is way off by 200 +pixels. Thus i would like to know if i can get the string draw size through java in the command environment. Or if there are other ways to get the size plz tell me i really need a sollution to this php bug.
Of course i tried to dig into the font class but it uses the X11 graphics which aren't available
any help is welcom

if you install the linux server as command prompt the X11 graphics (windows) arn't installed / started thus the java graphics awt is useless for it uses the X11 server
anyway i'll look into the font measuring for i'm getting wierd deviation in the counts of to scripts:
script 1 php based (first try)
1783 newwidth for str 2064 Fred Tanja
1806 newwidth for str 2064 <|>
1979 newwidth for str 2064 Plaats hier je bericht!
2002 newwidth for str 2064 <|>
2120 newwidth for str 2064 Martijn marcel
script 2 java based
1689 newwidth for str2064 Fred Tanja
1713 newwidth for str2064 <|>
1872 newwidth for str2064 Plaats hier je bericht!
1895 newwidth for str2064 <|>
2009 newwidth for str2064 Martijn marcel
see the wierd deviation of 120 pixels? the lengths where both gotten with php's imagepsbox (in java by calling an exernal script)
i just can't seem to figure out what is wrong it's the same string same font same size (those are read from the same config file ) anyway i'll get a clear head and try again tomorrow maybe its in the derived font
