So I agree that the above code will work. What if the file name contains <space>?
You are right - what I posted was thought to be an example/hint on how to improve, not a full blown solution. You'd need to concatenate ALL trailing fields into Ar to account for that, like AR[++n]=$9" "$10... or Ar[++n]=substr($0,50). Neither of these is really satisfying. I'd prefer to use sth. likestat on systems where it is available.
I have 1800 files in a directory. The file name is like out_cpty_XXXX. The "XXXX" vaires from file to file. I want to get the count of files with file name out_cpty_XXXX. How to get the count with just the partial file name?
Any help would be appreciated? (4 Replies)

Hi!
In our current directory there are around 35000 files.
Out of these a few thousands(around 20000) start with, "testfiles9842323879838".

file::stat
File::stat(3perl) Perl Programmers Reference Guide File::stat(3perl)NAME
File::stat - by-name interface to Perl's built-in stat() functions
SYNOPSIS
use File::stat;
$st = stat($file) or die "No $file: $!";
if ( ($st->mode & 0111) && $st->nlink > 1) ) {
print "$file is executable with lotsa links
";
}
if ( -x $st ) {
print "$file is executable
";
}
use Fcntl "S_IRUSR";
if ( $st->cando(S_IRUSR, 1) ) {
print "My effective uid can read $file
";
}
use File::stat qw(:FIELDS);
stat($file) or die "No $file: $!";
if ( ($st_mode & 0111) && ($st_nlink > 1) ) {
print "$file is executable with lotsa links
";
}
DESCRIPTION
This module's default exports override the core stat() and lstat() functions, replacing them with versions that return "File::stat"
objects. This object has methods that return the similarly named structure field name from the stat(2) function; namely, dev, ino, mode,
nlink, uid, gid, rdev, size, atime, mtime, ctime, blksize, and blocks.
As of version 1.02 (provided with perl 5.12) the object provides "-X" overloading, so you can call filetest operators ("-f", "-x", and so
on) on it. It also provides a "->cando" method, called like
$st->cando( ACCESS, EFFECTIVE )
where ACCESS is one of "S_IRUSR", "S_IWUSR" or "S_IXUSR" from the Fcntl module, and EFFECTIVE indicates whether to use effective (true) or
real (false) ids. The method interprets the "mode", "uid" and "gid" fields, and returns whether or not the current process would be allowed
the specified access.
If you don't want to use the objects, you may import the "->cando" method into your namespace as a regular function called "stat_cando".
This takes an arrayref containing the return values of "stat" or "lstat" as its first argument, and interprets it for you.
You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that
this still overrides your stat() and lstat() functions.) Access these fields as variables named with a preceding "st_" in front their
method names. Thus, "$stat_obj->dev()" corresponds to $st_dev if you import the fields.
To access this functionality without the core overrides, pass the "use" an empty import list, and then access function functions with their
full qualified names. On the other hand, the built-ins are still available via the "CORE::" pseudo-package.
BUGS
As of Perl 5.8.0 after using this module you cannot use the implicit $_ or the special filehandle "_" with stat() or lstat(), trying to do
so leads into strange errors. The workaround is for $_ to be explicit
my $stat_obj = stat $_;
and for "_" to explicitly populate the object using the unexported and undocumented populate() function with CORE::stat():
my $stat_obj = File::stat::populate(CORE::stat(_));
ERRORS
-%s is not implemented on a File::stat object
The filetest operators "-t", "-T" and "-B" are not implemented, as they require more information than just a stat buffer.
WARNINGS
These can all be disabled with
no warnings "File::stat";
File::stat ignores use filetest 'access'
You have tried to use one of the "-rwxRWX" filetests with "use filetest 'access'" in effect. "File::stat" will ignore the pragma, and
just use the information in the "mode" member as usual.
File::stat ignores VMS ACLs
VMS systems have a permissions structure that cannot be completely represented in a stat buffer, and unlike on other systems the
builtin filetest operators respect this. The "File::stat" overloads, however, do not, since the information required is not available.
NOTE
While this class is currently implemented using the Class::Struct module to build a struct-like class, you shouldn't rely upon this.
