how to let the perl script to run for each file
Hi,

I have more than 1 files in the directory. In bash, I can use
Code:
cd /work
 
for x in `ls`
do
:
: 
done

to run for each file in the directory.

How about in perl script?
Code:
filepath="ABC1"
open(FILE, $filepath) or die "$filepath cannot be opened.";
while(<FILE>) {
 :
 :
}
close(<file>)

because the open command just open the file ABC1 only. If I have ABC2, ABC3,ABC4 and ABC5 files.... how to let perl script also can run for the other files?

Thanks for you advise.

Constructor &; Destructor Documentation
   zipios::FilePath::FilePath (const string &path = '', boolcheck_exists = false)
       Constructor. Parameters:
	   path A string representation of the path.
	   check_exists If true is specified the constructor will check the existence and type of the path immidiately, instead of deferring that
	   task until it is needed.

       Definition at line 18 of file filepath.cpp.

Member Function Documentation
   void zipios::FilePath::check () const [protected]
       This function sets _checked to true, stats the path, to see if it exists and to determine what type of file it is. All the query functions
       check if _checked is true, and if it isn't they call check(). This means stat'ing is deferred until it becomes necessary.
