I've searched the man page for an option for the ls command to print the number of files in a directory. I'm moving files and folders around and thought a count of files would be a quick way to determine if I was missed one somewhere. Some "unix's" shells do this I think... maybe linux...
Anybody know how to do this real quick
System is: SunOS 5.10 Generic sun4u sparc SUNW,Ultra-5_10 KSH
I did this but is comes back with byte count rather than a file count.
ls -l |wc
You can add the -l option to wc, or you can do it in the shell itself, which will be much faster:
Does any one know how to get a recursive directory listing in long format (showing owner, group, permission etc) without listing the files contained in the directories.
The following command also shows the files but I only want to see the directories.
ls -lrtR * (4 Replies)
I've backed up several files to tape using tar, and wish to list those that have backed up.
% tar cvf /dev/rmt/2un /s_1/oradata/pgpub/config.ora
a /s_1/oradata/pgpub/config.ora 2 tape blocks
But when I go to list the files:
% tar tvf /dev/rmt/2un
tar: tape read error

I noticed the other day that after i used the find command to search for some files, the computer listed them twice -- first with just the names of the files (meaning ./(then the individual file names), then with the directory name, followed by the file names (./directory name/file name). I was... (2 Replies)
Hi ,
I am trying to find some files on a remote machine using the find command.
>ssh -q atukuri@remotehostname find /home/atukuri/ -name abc.txt
/home/atukuri/abc.txt
The above command works fine and lists the file, but if I want to do a long listing of files (ls -l) its not working . ... (2 Replies)

Hi,
I want to list all files present in directory those contains one specific word but exclude other.
If possible suggest unix commands instead of script to do so.
e.g.
List all files name from directory which are having "PROMOTION" word but not "LEN_PROMOTION".
Thanks (4 Replies)

devel::refcount
Devel::Refcount(3pm) User Contributed Perl Documentation Devel::Refcount(3pm)NAME
"Devel::Refcount" - obtain the REFCNT value of a referent
SYNOPSIS
use Devel::Refcount qw( refcount );
my $anon = [];
print "Anon ARRAY $anon has " . refcount($anon) . " reference
";
my $otherref = $anon;
print "Anon ARRAY $anon now has " . refcount($anon) . " references
";
DESCRIPTION
This module provides a single function which obtains the reference count of the object being pointed to by the passed reference value.
FUNCTIONS
$count = refcount($ref)
Returns the reference count of the object being pointed to by $ref.
COMPARISON WITH SvREFCNT
This function differs from "Devel::Peek::SvREFCNT" in that SvREFCNT() gives the reference count of the SV object itself that it is passed,
whereas refcount() gives the count of the object being pointed to. This allows it to give the count of any referent (i.e. ARRAY, HASH,
CODE, GLOB and Regexp types) as well.
Consider the following example program:
use Devel::Peek qw( SvREFCNT );
use Devel::Refcount qw( refcount );
sub printcount
{
my $name = shift;
printf "%30s has SvREFCNT=%d, refcount=%d
",
$name, SvREFCNT($_[0]), refcount($_[0]);
}
my $var = [];
printcount 'Initially, $var', $var;
my $othervar = $var;
printcount 'Before CODE ref, $var', $var;
printcount '$othervar', $othervar;
my $code = sub { undef $var };
printcount 'After CODE ref, $var', $var;
printcount '$othervar', $othervar;
This produces the output
Initially, $var has SvREFCNT=1, refcount=1
Before CODE ref, $var has SvREFCNT=1, refcount=2
$othervar has SvREFCNT=1, refcount=2
After CODE ref, $var has SvREFCNT=2, refcount=2
$othervar has SvREFCNT=1, refcount=2
Here, we see that SvREFCNT() counts the number of references to the SV object passed in as the scalar value - the $var or $othervar
respectively, whereas refcount() counts the number of reference values that point to the referent object - the anonymous ARRAY in this
case.
Before the CODE reference is constructed, both $var and $othervar have SvREFCNT() of 1, as they exist only in the current lexical pad. The
anonymous ARRAY has a refcount() of 2, because both $var and $othervar store a reference to it.
After the CODE reference is constructed, the $var variable now has an SvREFCNT() of 2, because it also appears in the lexical pad for the
new anonymous CODE block.
PURE-PERL FALLBACK
An XS implementation of this function is provided, and is used by default. If the XS library cannot be loaded, a fallback implementation in
pure perl using the "B" module is used instead. This will behave identically, but is much slower.
