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)
Hi i have a ques in Shell scripting:
ques: accept a filename as a command line argument. Validate the input and display the last modification date for that file.
Help pls. (4 Replies)
hi. I need help my programing friends :p
I need to list all the files with a certain name (for example FileName) by last modification date but only the one with the last date. If there are two files with the same name and same modification date it should print the both.
For example in this set... (6 Replies)
I realize this is basic and probably obvious, but I'm pulling my hair out. I'm guessing this is just some flag on the file command or somesuch, but I can't find it. Help me get unstuck please?
EDIT: I guess what I'm asking is once I've got the ls -l output for a file, what command do I use to... (3 Replies)
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)
How do i get the file modification date in number format (yyyy mm dd hh mm ss)
i used

Hello all !
I have a piece of code that generates the date of one day ago:
/usr/bin/gdate --date='1 day ago' | awk '{print $2 " " $3}'
Nov 3
I want the output to be in the form :

What other operation should I do for that ?

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.
