INITIALIZATION

If you never run perlbrew before, or you do not have a ~/.perlbrew directory, you should perform the initialization process by running:

    perlbrew init

This step needs to be done only once.

If latter on you need to change $PERLBREW_ROOT, you (and all other users who share the same $PERLBREW_ROOT will have to run this again to make it affective.

COMMAND: INIT

The init command should be manually invoked whenever you (the perlbrew user) upgrade perlbrew.

However, if the upgrade is done with self-upgrade command, or by running the one-line installer manually, this command is invoked automatically.

COMMAND: INSTALL

install [ perl-<version> | <version> ]

Build and install the given version of perl.

Version numbers usually look like "5.x.xx", or "perl-5.xx.x-RCx" for release candidates.

The specified perl is downloaded from the CPAN website, unless mirror setting are present.

install [ perl-blead | blead ]

A special way to install the blead version of perl, which is downloaded from this specific URL regardless of mirror settings:

    http://perl5.git.perl.org/perl.git/snapshot/blead.tar.gz
install /path/to/perl/git/checkout/dir

Build and install from the given git checkout dir.

install /path/to/perl-5.14.0.tar.gz

Build and install from the given archive file.

install http://example.com/mirror/perl-5.12.3.tar.gz

Build and install from the given URL. Supported URL schemes are http://, https://, ftp:// and file://.

COMMAND: UNINSTALL

Usage: perlbrew uninstall <name>

Uninstalls the given perl installation.

COMMAND: USE

Usage: perlbrew use [perl-<version> | <version> | <name>]

Use the given version perl in current shell. This will not effect newly opened shells.

Without a parameter, shows the version of perl currently in use.

COMMAND: SWITCH

Usage: perlbrew switch [ <name> ]

Switch to the given version, and makes it the default for this and all future terminal sessions.

Without a parameter, shows the version of perl currently selected.

COMMAND: LIST

Usage: perlbrew list

List the installed versions of perl.

COMMAND: AVAILABLE

Usage: perlbrew available

List the available versions of perl on CPAN.

COMMAND: OFF

Usage: perlbrew off

Temporarily disable perlbrew in the current shell.

Re-enables the default system Perl, whatever that is.

COMMAND: SWITCH-OFF

Usage: perlbrew switch-off

Permananently disable perlbrew. Use switch command to re-enable it. Invoke use command to enable it only in the current shell.

Re-enables the default system Perl, whatever that is.

COMMAND: ALIAS

Usage: perlbrew alias [-f] create <name> <alias>

    Create an alias for the installation named <name>.

Usage: perlbrew alias [-f] rename <old_alias> <new_alias>

    Rename the alias to a new name.

Usage: perlbrew alias delete <alias>

    Delete the given alias.

COMMAND: MIRROR

Usage: perlbrew mirror

Run this if you want to choose a specific CPAN mirror to install the perls from. It will display a list of mirrors for you to pick from. Hit 'q' to cancel the selection.

COMMAND: EXEC

Usage: perlbrew exec <command> <args...>

Execute command for all perls, one by one.

For example, run a Hello program:

    perlbrew exec perl -e 'print "Hello from $]\n"'

The output depends on your perl installations, and looks like this:

    perl-5.12.2
    ==========
    Hello word from perl-5.012002
    
    perl-5.12.3
    ==========
    Hello word from perl-5.012003
    
    perl-5.13.10
    ==========
    Hello word from perl-5.013010
    
    perl-5.14.0
    ==========
    Hello word from perl-5.014000

Notice that the command is not executed in parallel.

COMMAND: ENV

Usage: perlbrew env <name>

Low-level command. Use this command to see the list of environment variables that are set by perlbrew itself for shell integration.

The output is something similar to this (if your shell is bash/zsh):

    export PERLBREW_ROOT=/Users/gugod/perl5/perlbrew
    export PERLBREW_VERSION=0.31
    export PERLBREW_PATH=/Users/gugod/perl5/perlbrew/bin:/Users/gugod/perl5/perlbrew/perls/current/bin
    export PERLBREW_PERL=perl-5.14.1

You can also ask for the proper variables for a specific perl version.

COMMAND: SYMLINK-EXECUTABLES

Usage: perlbrew symlink-executables <name>

Low-level command. This command is used to create the perl executable symbolic link to, say, perl5.13.6. This is only required for development version of perls.

You don't need to do this unless you have been using old perlbrew to install perls, and you find youself confused because the perl that you just installed appears to be missing after invoking `use` or `switch`. perbrew changes its installation layout since version 0.11, which generades symlinks to executables in a better way.

If you just upgraded perlbrew (from 0.11 or earlier versions) and perlbrew switch failed to work after you switch to a development release of perl, say, perl-5.13.6, run this command:

    perlbrew symlink-executables perl-5.13.6

This essentially creates this symlink:

   ${PERLBREW_ROOT}/perls/perl-5.13.6/bin/perl
   -> ${PERLBREW_ROOT}/perls/perl-5.13.6/bin/perl5.13.6

Newly installed perls, whether they are development versions or not, does not need manually treatment with this command.

COMMAND: INSTALL-CPANM

Usage: perlbrew install-cpanm

Install the cpanm standalone executable in $PERLBREW_ROOT/bin.

For more rationale about the existence of this command, read <http://www.perlbrew.pl/Perlbrew-and-Friends.html>

COMMAND: INSTALL-PATCHPERL

Usage: perlbrew install-patchperl

Install the patchperl standalone executable in $PERLBREW_ROOT/bin. This is automaticall invoked if your perlbrew installation is done with the installer, but not with cpan.

For more rationale about the existence of this command, read <http://www.perlbrew.pl/Perlbrew-and-Friends.html>

COMMAND: SELF-UPGRADE

Usage: perlbrew self-upgrade

This command upgrades Perlbrew to its latest version.

COMMAND: VERSION

Usage: perlbrew version

Show the version of perlbrew.

COMMAND: LIB

Usage:

    perlbrew lib create <lib-name>
    perlbrew lib delete <lib-name>

The `lib` command is used to manipulate local::lib roots inside perl installations. Effectively it is similar to `perl -Mlocal::lib=/path/to/lib-name`, but a little bit more than just that.

A lib name can be a short name, containing alphanumeric, like 'awesome', or a full name, prefixed with a perl installation name and a '@' sign, for example, 'perl-5.14.2@awesome'.

Here are some a brief examples to use them:

    # Create libs by name
    perlbrew lib create nobita
    perlbrew lib create perl-5.12.3@shizuka

    perlbrew list     # See the list of use/switch targets.

    # Activate lib in current shell.
    perlbrew use perl-5.12.3@nobita
    perlbrew use perl-5.14.2@nobita

    # Activate lib in as default.
    perlbrew switch perl-5.14.2@nobita

    # Clean the lib
    perlbrew lib delete nobita
    perlbrew lib delete perl-5.12.3@shizuka

A "lib" is reference by it's name, which can be a short one consists of letters, or a fully-qualified one, prefixed with the perl installation name, and an `@` character in between. Short names are local to current perl. A lib name 'nobita' can refer to 'perl-5.12.3@nobita' or 'perl-5.14.2@nobita', depending on your current perl.

When invoking `use` or `switch` command to a lib, always use the long name for it might be ambigous. A simple rule: the name after `use` or `switch` should be in the output of `list`.

OPTIONS

-h| --help

prints this help.

-f| --force

Force installation of a perl.

-j

Enable parallel make and test (if supported by the target perl)

  perlbrew install -j 5 perl-5.12.3
-n| --notest

Skip the test suite

-q| --quiet

Make perlbrew command quieter.

-v| --verbose

Make perlbrew command say more.

For install command, this prints the building whole process to STDOUT.

--as

Install a given perl under an alias.

    perlbrew install perl-5.6.2 --as legacy-perl
-D, -U, -A

pass through switches to the perl Configure script.

    perlbrew install perl-5.10.1 -D usemymalloc -U uselargefiles

CONFIGURATION

PERLBREW_ROOT

By default, perlbrew builds and installs perls into $ENV{HOME}/perl5/perlbrew directory. To use a different directory, set this environment variable in your bashrc to the directory before running perlbrew.

UPGRADE NOTES

If you upgraded perlbrew from version 0.16 or older, you should do this cleanup your setup. Failure to do so might make the use command to fail.

Note the version of perl currently selected with perlbrew switch. Then turn perlbrew off, and switched back again with perlbrew switch previous-perl-version.
