[tien ho]

Hi Terry,
Thank you for your explication. Can we change this behaviour? I'm not sure 
but, I don't think I have the same behaviour with korn shell or c- shell, do 
I?
Can I have other shell (korn shell or c-shell), which runs on cygwin?
Thanks,
Tien

ctl-d, bash and java

[tien ho]

Hi everybody,
I'm a newbie in bash. I'm testing some examples of javacc. I'm using cygwin 
b20.1 (bash and make) on NT4.0, SP4, english version and jdk 1.2 to test 
javacc simple examples. I do need EOF (ctl-d) to shows the results.
Ctl-d is using to stop the cat in the command cat>myfile. It works fine in 
cygwin.

The behaviour of bash on ctl-d is quite special (nothing set in IGNOREEOF). 
If I'm right, it was defined the following:
If ctl-d is the first character, then it returns EOF, else delete the 
character under the cursor.

To test it:
I type the command abcd<ctl-d>, I will received the following message:
bash: abcd: command not found
If ctl-d is the first character, bash disappears.

To test with java, I wrote a very simple test program, which calls the 
function System.in.read(b[]). Following is the code:
public class sysIn {
    public static void main (String args[]) {
      int i;
      byte b[]= new byte[256];
      try
      {
        i = System.in.read(b);
      }
      catch (IOException ioEx)
      {
        System.err.println(ioEx);
        return;
      }
      System.out.println(i);
      for (int j=0; j < i; j++)
        System.out.print(b[j]+" ");
      System.out.println();
    }
  }

It displays 1 13 (code of ctl-d), when ctl-d is keyed.
Bash disappers, when "abcd<ctl-d>" were keyed. How can I explain it?

How it reacts with fgets()?
#include <stdio.h>
int main(int argc, char** argv)
{
  char s[256];
  if (fgets(s,256, stdin ))
  {
    printf("\nlen: %i\n", strlen(s));
    printf("text: %s\n", s);
  }
  else
    printf("\nempty\n");
  return (1);
}
When I start the test and gave abcd<ctl-d>, I recieved:
len: 4
text: abcd
bash-2.02$
I gave <ENTER>, bash treats the command abcd and returns
bash: abcd: command not found

How can I changed the behaviour of bash, so that I can received ctl-d key 
stroke and input buffer will be flushed?

Thank you for helps
Tien

IOW, bash (or readline) is using c-d as a way of copying the line to the keyboard buffer; or *not clearing it out*. Then when the next key is pressed the earlier text reappears!

ctl-d, bash and java

[tien ho]

Hi everybody,
I'm a newbie in bash. I'm testing some examples of javacc. I'm using cygwin 
b20.1 (bash and make) on NT4.0, SP4, english version and jdk 1.2 to test 
javacc simple examples. I do need EOF (ctl-d) to shows the results.
Ctl-d is using to stop the cat in the command cat>myfile. It works fine in 
cygwin.

The behaviour of bash on ctl-d is quite special (nothing set in IGNOREEOF). 
If I'm right, it was defined the following:
If ctl-d is the first character, then it returns EOF, else delete the 
character under the cursor.

To test it:
I type the command abcd<ctl-d>, I will received the following message:
bash: abcd: command not found
If ctl-d is the first character, bash disappears.

To test with java, I wrote a very simple test program, which calls the 
function System.in.read(b[]). Following is the code:
public class sysIn {
    public static void main (String args[]) {
      int i;
      byte b[]= new byte[256];
      try
      {
        i = System.in.read(b);
      }
      catch (IOException ioEx)
      {
        System.err.println(ioEx);
        return;
      }
      System.out.println(i);
      for (int j=0; j < i; j++)
        System.out.print(b[j]+" ");
      System.out.println();
    }
  }

It displays 1 13 (code of ctl-d), when ctl-d is keyed.
Bash disappers, when "abcd<ctl-d>" were keyed. How can I explain it?

How it reacts with fgets()?
#include <stdio.h>
int main(int argc, char** argv)
{
  char s[256];
  if (fgets(s,256, stdin ))
  {
    printf("\nlen: %i\n", strlen(s));
    printf("text: %s\n", s);
  }
  else
    printf("\nempty\n");
  return (1);
}
When I start the test and gave abcd<ctl-d>, I recieved:
len: 4
text: abcd
bash-2.02$
I gave <ENTER>, bash treats the command abcd and returns
bash: abcd: command not found

How can I changed the behaviour of bash, so that I can received ctl-d key 
stroke and input buffer will be flushed?

Thank you for helps
Tien
