file list

[Xiao Ma]

I want to create a list of all the .java files in one directory and all
the subdirectories in one line. I can use "dir /s /b *.java" but it's in
multiple lines.

The goal is to use this list when I compile all the .java files with
javac. I am new to this, so please feel free to give me some suggestion.

Thanks!

How many files do you expect to be returned by this directory command?
Which version of Windows are you running? The length of the command
prompt command line in Win 95 and Win 98 cannot exceed 127 bytes. So
if you align all the filenames from the directory command into a single
line, will your compile command plus all the filenames exceed 127 bytes?

If you are using Win NT then you are not subject to this limitation.

Here is a batch file that will put all the filenames output from a directory

command into one environment variable. Hopefully, it will be run with
a restrictive enough argument so that the output will not overflow the
command line.
