Zmcgrew writes 'From Daemon News: 'The decision was made to remove Perl from the FreeBSD -current base system [earlier story ]. Perl will be supported as a port that the user can install after the base installation, however it will no longer be required. Mark Murray put out a call to the -current. FreeBSD's binary package manager, pkg, can be used to easily manage the installation of pre-compiled applications—the FreeBSD equivalent Debian and RPM packages. In this tutorial, we will show you how to manage packages on FreeBSD 10.1. Under FreeBSD you can use pkg_add command or ports system. The FreeBSD Ports Collection is a package management system that provides an easy and consistent way of installing software packages on the FreeBSD. Usually ports is located at /usr/ports directory. There are 3 different methods available to search a port name.
FreeBSD install Perl language. Practical Extraction and Report Language or Perl can be installed using FreeBSD ports or binary package system. Perl is a language optimized for scanning arbitrary text files, extracting information from those text files, and printing reports based on that information.

libpkg
pkg is built on top of libpkg, a new library to interface with packageregistration backends.It abstracts package management details such as registration, remoterepositories, package creation, updating, etc.
pkg package format
pkg package format is a tar archive which can be raw, or use the followingcompression: gz, bzip2 and xz, defaulting in xz format.
The tar itself is composed in two types of elements:
- the special files at the beginning of the archive, starting with a '+'
- the data.
The metadata
pkg uses several files for metadata:
- +COMPACT_MANIFEST
- +MANIFEST
COMPACT_MANIFEST
This is a subset of the information included in the main MANIFEST,omitting the lists of files, checksums, directories and scripts.It contains the information used to build the repository catalogue.
MANIFEST
The manifest is in UCL format, it contains all theinformation about the package:
Valid scripts are:
- pre-install
- post-install
- install
- pre-deinstall
- post-deinstall
- deinstall
- pre-upgrade
- post-upgrade
- upgrade
Script MUST be in sh format.Nothing else will work.The shebang is not required.
When the manifest is read by pkg_create files and dirs can use analternate format:
This allows overriding the users, groups and mode of files anddirectories during package creation.So, for example, this allows to creation of a package containingroot-owned files without being packaged by the root user.
Local database
When a package is installed, it is registered in a SQLite database.
The SQLite database allow fast queries and ACID transactions. It alsoallows finding the reverse dependencies reliably without a needing the+REQUIRED_BY hack.
In order to save space the MTREE is only stored once, which save 18K perinstalled package.
pkg supports a
register
command to register packages into the SQLitedatabase from the ports. The register command can execute the install script,show pkg-message, ...Installing packages
pkg add
can install a package archive from the local disk, or from aremote FTP/HTTP server.If only a package name is given, it will search the repository cataloguesand download and install the package if it exists. Any dependencies will bedownloaded and installed first.
This is possible because we have the dependency information in thecatalogue of the remote repository.
pkg add
will check if the user attempts to install a package builtfor another arch or release.Upgrading packages
pkg also supports upgrades of binary packages.
pkg will compare the versions of installed packages and those available inthe repository. It will compute the proper update order and apply them.
Deleting packages
pkg delete
will remove a package, and (depending on the command linearguments) any other packages that depend on what you're trying todelete.Directory leftovers are automatically removed if they are empty andnot in the MTREE.
Installing pkg
Install Perl Centos
There are three ways to install pkg: two for general day-to-day use,and the third if you want to help with pkg development.
Pkg bootstrap
All supported versions of FreeBSD now contain /usr/sbin/pkg a.k.apkg(7). This is a small placeholder that has just the minimumfunctionality required to install the real pkg(8).
To use, simply run any pkg(8) command line. pkg(7) will intercept thecommand, and if you confirm that is your intention, download thepkg(8) tarball, install pkg(8) from it, bootstrap the local packagedatabase and then proceed to run the command you originally requested.
More recent versions of pkg(7) understand
pkg -N
as a test to see ifpkg(8) is installed without triggering the installation, andconversely, pkg bootstrap[-f]
to install pkg(8) (or force it to bereinstalled) without performing any other actions.pkg in Ports
pkg-1.0 release was committed to the the ports tree on 30th August2012, and a series of further releases are planned. To install thelatest release version:
Building pkg using sources from Git [FreeBSD]
In order to build pkg from source, you will need to have Gnuautotools and some other tools installed.
The next thing to do is to get the pkg sources installed on your machine.You can grab a development snapshot of pkg from the pkg GitHub repository
To get the latest version of pkg from the Git repo, just clone it:
or
Or you can take an already tagged release of pkg from the above webpage as well.Just open your browser and download the release you want.
Once you have the pkg sources, installing it is fairly easy:
Now you should have the latest pkg installed on your system. Notethat this build and install procedure does not update the localpackage database at all, so you will get some odd effects due to thepackaging system being misled into thinking an older version of pkg isinstalled.
Note: if you're running anything other than FreeBSD or DragonFly, youwill need to do some porting work. The pkg(8) codebase should bereasonably portable onto anything with a c99 compiler, POSIX compliantsystem and capable of running Gnu autotools. However, various placesin the pkg(8) code make assumptions about OS specific behaviour. Ifyou do try anything like this, we'd be very interested to hear how youget on.
Building pkg using sources from Git [OpenBSD and Bitrig]
A quick usage introduction to pkg
In this section of the document we will try to give a quick and dirtyintroduction on the practical usage of pkg - installing packages,searching in remote package repositories, updating remote packagerepositories and installing from them, etc.
Getting help on the commands usage
In order to get help on any of the pkg commands you should use the
pkg help <command>
command, which will take the man page of the specified command.In order to get the available commands in pkg, just execute
pkg help
Querying the local package database
In order to get information about installed packages use the
pkg info
command.pkg info
will query the local package database and displayinformation about the package you are interested in.To list all install/registered packages in the local database, usethis command:
For more information on querying the local package database, pleaserefer to pkg-info(1) man page.
Installing packages
Packages are installed either from a repository, from the results of alocal compilation of software via the ports or from a pkg tarballindependently obtained from some other source.
A repository is a collection of packages which have been gatheredtogether, had a catalogue created and then published, typically byexposing the repository via HTTP or some other networking protocol.You can also publish a repository from a local or NFS mountedfilesystem (using file:// style URLs) or via SSH (using ssh:// URLs.)
Adding pkg tarballs directly
In order to install the package foo-1.2.3 from a local pkg tarball,use a command similar to the following:
You will need to make sure that all dependencies of foo-1.2.3 areeither also available as tarballs in the same directory, or previouslyinstalled by other means.
You can also install the package foo-1.2.3 tarball from a remotelocation using the FTP/HTTP protocol. In order to do that you coulduse a command similar to the following:
Which works in exactly the same way, except that it fetches thepackage tarballs using the protocol indicated by the URL.

Working with a remote package repository
![Package Package](/uploads/1/2/6/8/126880385/627240511.png)
While pkg(8) can deal with individual package tarballs, the real powercomes from the use of repositories, which publish a 'catalogue' ofmeta-data about the packages they contain.
You can configure pkg(8) to use one or several repositories.Supported versions of FreeBSD now contain a default configuration outof the box:
/etc/pkg/FreeBSD.conf
which is setup to install packagesfrom the official package repositories.To add additional repositories, create a per-repository configurationfile in
/usr/local/etc/pkg/repos
-- it doesn't matter what thefilename is other than it must match '*.conf' and you should add a'priority' setting indicating the preference order. This is just aninteger, where higher values indicate the more preferred repositories.Priority defaults to 0 unless explicitly stated. This is the valuefor the default /etc/pkg/FreeBSD.conf
To disable the default FreeBSD.conf, create a file
/usr%2
