Need help with UNIX command to get the latest file from list of files with timestamp
Hi All,
I have list of files like below with name abcxyz.timestamp. I need a unix command to pick the latest file from the list of below files. Here in this case the lates file is abcxyz.20190304103200. I have used this unix command "ls abcxyz*|tail -1" but i heard that it is not the appropriate one which may not be successful all the time.I was told to use a command by sorting the files based on the timestamp. Please do the needful.
Thanks
Rakesh

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.
