Hi,
Thanx for your guys help. I have also seen this example from Thinking in
Java and i know how to retrieve file information but then my requirement is
just to get :
- [directory name] which will be shown when we execute dir filename /s, this
i am doing programmatically using Runtime class exec command and i some how
get the result of the search in a String. Since i am doing a file search
operation i am using this particular command to retrieve those file
location, once i get that location then i can get all the information of
those files. Code is like this :
String filename = "wherever.mp3";
Runtime r = Runtime.getRuntime();
Process p = r.exec("dir " + filename + " /s");
BufferedReader kbdInput =
new BufferedReader(new InputStreamReader(p.getInputStream()));
String cmdOutput;
while((cmdOutput = kbdInput.readLine()) != null)
System.out.println(line);
now when i print [ String line ] i get output something like this:
Directory of C:\
12/30/01 07:54p 3,174,400 whenever.mp3
1 File(s) 3,174,400 bytes
Directory of C:\mp3
12/30/01 07:54p 3,174,400 whenever.mp3
1 File(s) 3,174,400 bytes
Total Files Listed:
2 File(s) 6,348,800 bytes
959,447,040 bytes free
from this output i just need
1. c:\ - directory name for the first result.
2. c:\mp3 - directory name for the second result.
Since there is no delimiters in the above output and there is no
consistency in spacing i having problem in retrieving the above directory
names.
Guys i am also trying.
Looking forward for your response and wish you all a Happy and
Prosperous New Year 2002.
With Regards,
karthikeyan.
