Hi--
Ok. I have now found that:
find -x -ls
will do what I need as far as finding all files on a particular volume. Now I need to sort the results by the file's modification date/time.
Is there a way to do that?
Also, I notice that for many files, whereas the man for find says ls is... (8 Replies)
I am using th following to get the percentage and have never used bc before:
percent=$(echo "scale=4;(34117/384000)*100" | bc)
8.884600
percent=$(echo "scale=2;(34117/384000)*100" | bc)

Why do I get the results of 8.00 instead of 8.88 when using a scale of 2. I only want 2 decimal... (2 Replies)

Hi all,
I am writing script that returns the size of each disk or partition when called. I am using FDISK -l and parsing the results to get the result I want. When I execute fdisk -l it shows correct results, BUT when I execute the same thing with results to be put in a variable, I get strange... (5 Replies)
Here is the code, but the list is not sorted properly (alphabetically)?

Hi,
I have a problem with a shell script.
The script should find all .cpp and .h files and list them.
With:
for file in `find $src -name '*.h' -o -name '*.cpp'
it gives out this:
H:\FileList\A\E\F\G\newCppFile.cpp
H:\FileList\header01.h
H:\FileList\B\nextCppFile.cpp

Disclaimer, I've been a Linux admin for a while but don't frequently setup rsysnc jobs.
Here's the command I'm running on CentOS 5.5, rsync 2.6.8:

/src has 1.5 TB of data, /dest/ is a new destination and started out empy. Oh ya, both... (4 Replies)
I want to remove any files that are older than 2 days from a directory. It deletes those files. Then it comes back with a message it is a directory. What am I doing wrong here?

Using the 'strings' command and piping the result to 'sort' is producing strange results. I get block of lines that begin with asterisks, then a block that begins with some text, then more lines that begin with asterisks. The actual content is correct - lines beginning with asterisks is the... (5 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.
