Good morning,
I would like to find all files of a certain type and display their name as well as their modification date.
In order to do this, I would do the following:
find ./ -name *.csv | ????????
My question: what to put after the pipe instead of the question marks? Is there a basic... (5 Replies)
Hi
I'd like to know if is it possible to find files given a certain modification date (say, 01-05-2006, that's 1st of May 2006)
I can calculate the days backward:
find / -ctime 23
but I wish to search by exact modification day
Thanks (5 Replies)
Goodmorning,
I have a server with solaris 2.6 installed.
Is it possible modify system date only temporary that, automatically, after a reboot, I can have again the date after the temporary mofication?
I don't want to use "date" command after reboot for tidy up date. I only want to find a... (2 Replies)
Hi,
I was very surprised to not be able to find an answer to this question despite my best efforts in Google and elsewhere. Maybe it's a good thing as it forced me to finally become a member in this great forum that i use frequently.
Ok my question:

Hi, I'm executing a script to check if a file has been modified on a shared folder.
I use this to start another script every time the file has been modified.
To do this I use the 'ls' command to get the last modification date of the file.
My problem is that the computer hosting the shared... (5 Replies)
Hi everyone,
I have files like file1_Mod.txt, file2_Mod.txt. I want to rename the old files with the last modification date. I write the below script to rename with current date, but I donīt know how to use "date -r" to get the last modification date with the same format I have below... (5 Replies)
I'm trying to get the date output to be in the form yyyy-mm-dd (e.g. 2013-01-18)
!/bin/sh
modDate=$(stat -c %y $1)
echo $modDate >> $1
When I run this on another file (by typing ./dateScript theFile.txt), I keep getting this message:
stat: illegal option -- c
What's wrong with my code... (2 Replies)
First, oh great Unix gurus, forgive if this is a stupid question.
Unix/Linux is not my main thing but I have been programming in C/C++ for many years. I will do my best to be specific.
I have a program in C/C++ that needs to modify the time of a given file. Currently I do this using utime()... (5 Replies)

Hi,
In a folder, there are files. I have a script which reads the current date and subtract the modification date of each file.
How do I achieve this?

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.
