Using the filenames as the ONLY time reference:
Using file mtimes (last time written to, the default for ls -l )
The inode time ls -c abcd* is another internal time kept. This is almost always the file creation time. File creation time (birth time) is not universal, older UNIXes filesystems do not support it.
Since your question vague this is about the best we can do for you. We need your shell and your OS (uname -a shows this) to do better.

I was wondering if there was a command to move files from one directory to another subdirectory based on the timestamp, i.e. moving from directory A files that have a timestamp of before the year 2005 into directory B. Directory B is a subdirectory located in directory A. I was advised to... (4 Replies)

we want to fetch the latest file in a given directory and also the file name should match the below pattern
Example file name ->hrdata-2015-10-13-16-45-26.xml(2015-10-13-16-45-26- it is not current timestamp, we just need to check for the pattern)
We expect the file will have the... (3 Replies)

inc::latest
inc::latest(3pm) User Contributed Perl Documentation inc::latest(3pm)NAME
inc::latest - use modules bundled in inc/ if they are newer than installed ones
SYNOPSIS
# in Build.PL
use inc::latest 'Module::Build';
DESCRIPTION
The "inc::latest" module helps bootstrap configure-time dependencies for CPAN distributions. These dependencies get bundled into the "inc"
directory within a distribution and are used by Build.PL (or Makefile.PL).
Arguments to "inc::latest" are module names that are checked against both the current @INC array and against specially-named directories in
"inc". If the bundled version is newer than the installed one (or the module isn't installed, then, the bundled directory is added to the
start of <@INC> and the module is loaded from there.
There are actually two variations of "inc::latest" -- one for authors and one for the "inc" directory. For distribution authors, the
"inc::latest" installed in the system will record modules loaded via "inc::latest" and can be used to create the bundled files in "inc",
including writing the second variation as "inc/latest.pm".
This second "inc::latest" is the one that is loaded in a distribution being installed (e.g. from Build.PL). This bundled "inc::latest" is
the one that determines which module to load.
Special notes on bundling
The "inc::latest" module creates bundled directories based on the packlist file of an installed distribution. Even though "inc::latest"
takes module name arguments, it is better to think of it as bundling and making available entire distributions. When a module is loaded
through "inc::latest", it looks in all bundled distributions in "inc/" for a newer module than can be found in the existing @INC array.
Thus, the module-name provided should usually be the "top-level" module name of a distribution, though this is not strictly required. For
example, Module::Build has a number of heuristics to map module names to packlists, allowing users to do things like this:
use inc::latest 'Devel::AssertOS::Unix';
even though Devel::AssertOS::Unix is contained within the Devel-CheckOS distribution.
At the current time, packlists are required. Thus, bundling dual-core modules may require a 'forced install' over versions in the latest
version of perl in order to create the necessary packlist for bundling.
USAGE
When calling "use", the bundled "inc::latest" takes a single module name and optional arguments to pass to that module's own import method.
use 'inc::latest' 'Foo::Bar' qw/foo bar baz/;
Author-mode
You are in author-mode inc::latest if any of the Author-mode methods are available. For example:
if ( inc::latest->can('write') ) {
inc::latest->write('inc');
}
loaded_modules()
my @list = inc::latest->loaded_modules;
This takes no arguments and always returns a list of module names requested for loading via "use inc::latest 'MODULE'", regardless of
whether the load was successful or not.
write()
inc::latest->write( 'inc' );
This writes the bundled version of inc::latest to the directory name given as an argument. It almost all cases, it should be '"inc"'.
bundle_module()
for my $mod ( inc::latest->loaded_modules ) {
inc::latest->bundle_module($mod, $dir);
}
If $mod corresponds to a packlist, then this function creates a specially-named directory in $dir and copies all .pm files from the
modlist to the new directory (which almost always should just be 'inc'). For example, if Foo::Bar is the name of the module, and $dir
is 'inc', then the directory would be 'inc/inc_Foo-Bar' and contain files like this:
inc/inc_Foo-Bar/Foo/Bar.pm
Currently, $mod must have a packlist. If this is not the case (e.g. for a dual-core module), then the bundling will fail. You may be
able to create a packlist by forced installing the module on top of the version that came with core Perl.
As bundled in inc/
All methods are private. Only the "import" method is public.
