How to search for files using wildcards * and ?.

Hi All,
I've been searching the forum for a couple of hours now and have been unable to find a good example of how to search a directory (Windows OS) for a file using wildcards * and/or ?. Does anyone out there have a good example that they can share with me?
Thanks

Hi All,
First of all I want to thank everyone for taking the time to respond to my question. All of your responses where greatly appreciated.
I took the example code that was posted by rkconner, thanks rkconner, and modified it to allow me to search for files in a directory that contain * and/or ?. Yes, I said and/or! Meaning that you can use them both in the same file name, example: r??d*.t* would find readme.txt.
I've posed my complete and thoroughly document code below. I hope it is very helpful to other as I have searched many forums and spent many hours today trying to resolve this problem.
Enjoy
* File Name: WildcardSearch.java
* Date: Jan 9, 2004
* This class will search all files in a directory using the
* asterisk (*) and/or question mark (?) as wildcards which may be
* used together in the same file name. A File [] is returned containing
* an array of all files found that match the wildcard specifications.
* Command line example:
* c:\>java WildcardSearch c:\windows s??t*.ini
* New sWild: s.{1}.{1}t.*.ini
* system.ini
* Command line break down: Java Program = java WildcardSearch
*                          Search Directory (arg[0]) = C:\Windows
*                          Files To Search (arg[1]) = s??t*.ini
* Note: Some commands will not work from the command line for arg[1]
*        such as *.*, however, this will work if you if it is passed
*        within Java (hard coded)
* @author kmportner
import java.io.File;
import java.io.FilenameFilter;
public class WildcardSearch
     private static String sWild = "";
      * @param args - arg[0] = directory to search, arg[1] = wildcard name
     public static void main(String[] args)
          String sExtDir = args[0]; // directory to search
          sWild = args[1];   // wild card to use - example: s??t*.ini
          sWild = replaceWildcards(sWild);
          System.out.println("New sWild: " + sWild);
          File fileDir = new File(sExtDir);
          File[] arrFile = fileDir.listFiles(new FilenameFilter()

               System.out.println(arrFile.getName());
     }     // end main
     * Checks for * and ? in the wildcard variable and replaces them correct
     * pattern characters.

Please answer. how to search for files

Hi,
We need an integration with SAP. They send us files in the format: yyyymmddhhmiss.atv
For example we receive following files:
20050503101115.atv
20050504101115.atv
20050505101115.atv
So, we dont know how to search for all files with extensions ".atv" in the directory.
We are using PLSQL. Is there some way to resolve with UTL_FILE?
Any other suggestion?

A possibility:
In sqlplus, issue a HOST command to list the files to a file:
ls *.atv > atv_dir.txt
Then use utl_file to read atv_dir.txt and parse it for the file names.
You could put the filenames in a pl/sql table and use that as loop control.

How to search for file in a directory or subdirectories?

I need ur help urgently. I'm currently doing a java project in which the program should be able to do file searching.
For eg. if I key in a.jpg, it should display C:\pictures\a.jpg (a.jpg is stored in a folder called "pictures")
But the problem is that my program is only able to search in the C drive only.
If I move the file into a folder in the C drive, my program cannot detect this.
Can you help me to solve this problem? I'm really looking forward for your reply.
Thanks. Here are the codes.
import java.io.*;
import java.awt.*;
class FindFile
     public static void main(String args[]) throws IOException
          //reads the user input
          BufferedReader userInput;
          while(true)
                    userInput = new BufferedReader(new InputStreamReader(System.in));
                    String s = userInput.readLine();
                    //quits the system
                    if(s.equals("/quit"))
                         System.exit(0);
                    //if user does not key in anything, prompt msg appear
                    else if(s.equals(""))
                         System.out.println("Command Syntax: java ListFiles <filename>");
                         System.out.println("<filename> - The full name of a file and extension (i.e., test.txt)");
                    else if(userInput != null)
                         String t = "c:";
                         File f = new File(t);
                         String[] files = f.list();
                         char[] qwet;
                         boolean test = false;
                         //check for the file name and compare with the user input
                         for (int i = 0; i < files.length; i++)
                              if(files.equals(s))
                                   System.out.println("");
                                   System.out.println("File Found");
                                   System.out.print("The File Found at This Path: ");
                                   //display the path
                                   System.out.print(f.getAbsolutePath());
                                   System.out.println(files[i]);
                                   test = true;
                                   break;
                         //if file does not exist
                         if(test == false)
                              System.out.println("File Not Found");

well, i think the best solution would be make a recursive search through the directory tree. I don't know if you are familiar to this, but the functions that searches for the file would look like this:
public String searchFile(String name) {
File[] roots = File.listRoots();   // List all file roots (in windows the different units, c:, d:, etc.)
for (int i = 0 ; i < roots.length() ; i++) {
    String aux = recursiveSearch(roots, name);
if (aux != null) {   // If the "recursiveSearch" returns something different than null is that the file is founded, so we return the path.
return aux;
return null; // If we get there nothing has been found
private String recursiveSearch(File f, String name) {   // f is the directory to search for the file with name "name"
File[] childs = f.listFiles();
for (int i = 0 ;i < childs.length ; i++) {
if (childs[i].isDirectory()) { // If that is a directory we search inside
String aux = recursiveSearch(childs[i], name);
if (aux != null) {   // We have found it inside this directory
return aux;
} else { // Is a regular file
if (name.compareTo(childs[i].getName()) == 0) {   // If the file is what we want we return his path
return childs[i].getCanonicalPath();
// If we get here is because the file is not inside the directory or any subdirectory on it
return null;
You should just call the function searchFile(name) with the name of the file you want to search. If it finds one with this name it will return his absolute path, and if he doesn't the desired file he will return null.
If you don't understand anything just ask.
(Note: i have not tested this code, so can be some mistakes, but it think it is almost correct. mmmhh don't now why, but [ & ] appear in my code as < & >. Just replace them.).
Hope that helps.

How to search for file within compressed file

I hope i can explain this correctly, I apologize in advance.
What is the command to search for a file that may/may not exist within another compressed file?
Situation is that I have a cron job that compresses the files in a folder on a scheduled date. I now need to search for a file that may exists in one of the several compressed files, which was a result of the cron job.
Thanks in advance

There's an open source utility called zgrep. You can probably get it from http://www.sunfreeware.com/ .

How to search for folders using jsp ( or any other way)?

Hey All,
It's my first time writing here and i hope i can get some help ... i have created a payroll system using java and jsp techniques and mysql as the database, i want to create a backup page that will let the use to choose the destination folder for the back up, the backup is basically a mysqldump command that will get the destination folder as an argument and create the sql file there. the problem is i couldn't find anyway to let the user browse his local machine and choose the folder , which in returns return the folder path to be used in mysqldump....
I know that html have <input type=file> but it's used for selecting file not folder...
can someone come up with a solution for me coz it's urgent and i have to finish the project by the end of this week.,.
peace!

Also you can use an OUTPUT clause ( need to modify your DML operations)
create table itest ( i int identity not null primary key, j int not null unique )
create table #new ( i int not null, j int not null)
insert into itest (j)
output inserted.i, inserted.j into #new
select o.object_id from sys.objects as o
select * from #new
drop table #new, itest;
go
The example below shows code that uses OUTPUT clause in UPDATE and DELETE statements to insert rows into an audit table.
create table t ( i int not null );
create table t_audit ( old_i int not null, new_i int null );
insert into t (i) values( 1 );
insert into t (i) values( 2 );
update t
set i = i + 1
output deleted.i, inserted.i into t_audit
where i = 1;
delete from t
output deleted.i, NULL into t_audit
where i = 2;
select * from t;
select * from t_audit;
drop table t, t_audit;
go

How to search for files everywhere?

When I use Apple-F to find files, apparently only some folders are searched, even when I have "This Mac" selected. For example, I cannot seem to find anything in ~/Library. Can I force it to search all folders that I have permission to view? Thanks for any help!

to search those folders you need to include system files in your search.
After you enter command+f to bring up a search window, click on "Kind" and scroll to "other". You'll get a popup window will all possible search parameters. Choose "system files" and set it to "include". To see even more items, select "Spotlight items" and include those.

How can i render a dynamic html file in jsp page

Hi everybody,
i am trying to render a dynamic html file in jsp page with the result of querying a database.
The response of the query is a xml document. And i have a stylesheet to transfer it to html.
How can i render the html in a jsp file?

I am using below code for HTML files
private var appFile:String="index.html";
if (StageWebView.isSupported)
                    currentState = "normal";
                    webView.stage = stage;
                    webView.viewPort = new Rectangle( 10, 130, (stage.stageWidth)-20, 750 );
                    var fPath:String = new File(new File("app:/assets/html/aboutus/"+ appFile).nativePath).url;
                    webView.loadURL(fPath);
                    addEventListener(ViewNavigatorEvent.REMOVING,onRemove);
                else {
                    currentState = "unsupported";
                    lblSupport.text = "StageWebView feature not supported";
above code is working fine for me.

How do I exclude directories from Finder search results? I'm trying to find the biggest FILES on my computer and it keeps showing me "Macintosh HD" as the biggest, how can I search for files of type "NOT folder/directory"?

Basically I've lost 10GB of free space over the last few weeks so my plan was to search for files modified in the last 2 weeks in order to figure out which ones are big and where that space went.
So I open finder, go to "File > Find", and enter a search:
Modified > In the last 2 weeks
All fine so far.
Problem is, it's showing whole directories as results. Which essentially means that when I order the list by size, Macintosh HD is at the top, followed by "Users", then "Applications", then one of my bigger movie files, then "Library", etc.
How can I do a search which will ignore folders? I want individual files. Knowing that Macintosh HD is the biggest item on my computer and was modified in the last 2 weeks is utterly useless to me.
Older versions of Finder in OS 9 had a feature where you could search for "files, whose type "IS NOT" folder", but OS X doesn't seem to have such a feature.
Can anyone help?

How much free space is on the HD, where has all the space gone?
OmniDiskSweeper is likely the easiest/best, and is now free...

Trouble searching for files in Pages

For some reason, when I go to open a file in Pages '09, some of them will not show up if I type in the file name in the search in the upper right hand corner of the window. I know for 100% certainty I have the file name correct - to make sure it is a search problem and not my memory having issues I would search for a file and while looking at the file name, type it in... and I would get 0 search results. I clicked for it to search by file name. The files it does not seem to be able to recognize are file names with Japanese as part of the file name that were saved using my Mac (MacBook Pro - OS X 10.6.8). Files with Japanese in the file name saved on windows computers and transfered via my flashdrive have no issues being found. I can open the files, so that is not the problem. And, if I scroll through all the files I can find it. The problem is that sometimes I don't remember the full file name - especially which word I put first - so having to scroll through all my files to find the one I want is rather annoying. I would prefer to be able to search for any of my Pages files. Is there anyway to fix this? Or is the Pages search just not made to be compatible with any language other than English? (I am not sure if it is relavant, but if I search for the files via Spotlight, I can find them using the English or Japanese portion of the file name. Even though Finder does not allow me to use the Japanese portion of the file name in a search, the files do show up if I use the English portion of the file name.)
Any help of why this problem exists and if there is any way to fix would be very much appreciated.

Hi KJ,
in the search in the upper right hand corner of the window.
The Pages window? I can't see a search box.
Do you mean Spotlight? (The magnifying glass icon?)
System Preferences > Personal > Spotlight > Search Results.
Make sure there is a tick next to Documents.
Spotlight will find file names (partial or complete match) or a word or phrase within files.
Regards,
Ian

When importing files, my view window to search for files is really small, how do I make it bigger so I can actually search for files?

When importing files, my view window to search for files is really small, how do I make it bigger so I can actually search for files?

How big this is depends on the size of your screen. On a 13" it is really small. But you can improve things a bit. Click the green button to make the import window fill the screen.
Drag the area between the file list and the preview area up or down to increase one or the other:

I have a external hard drive connected, Finder will not let me search for files in the external hard drive how do i search in a hard drive

i have a external hard drive connected, Finder will not let me search for files in the external hard drive how do i search in a hard drive

What are you using to search? You should be able to search any drive in from the Finder. If you're having trouble, try "EasyFind" from the App Store (free). You can search any volumes with it.
