NAME

Setup::Unix::Group - Setup Unix group (existence)

VERSION

This document describes version 0.14 of Setup::Unix::Group (from Perl distribution Setup-Unix-User), released on 2017-07-10.

FUNCTIONS

addgroup

Usage:

 addgroup(%args) -> [status, msg, result, meta]

Add group.

This function is not exported.

This function is idempotent (repeated invocations with same arguments has the same effect as single invocation). This function supports transactions.

Arguments ('*' denotes required arguments):

  • etc_dir => str (default: "/etc")

    Location of passwd files.

  • gid => int

    Add with specified GID.

    If not specified, will search an unused GID from min_new_gid to max_new_gid.

    If specified, will accept non-unique GID (that which has been used by other group).

  • group => str

    Group name.

  • max_gid => int (default: 65534)

    Specify range for new GID.

    If a free GID between min_gid and max_gid is not available, an error is returned.

    Passed to Unix::Passwd::File's max_new_gid.

  • min_gid => int (default: 1000)

    Specify range for new GID.

    If a free GID between min_gid and max_gid is not available, an error is returned.

    Passed to Unix::Passwd::File's min_new_gid.

Special arguments:

Returns an enveloped result (an array).

First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

delgroup

Usage:

 delgroup(%args) -> [status, msg, result, meta]

Delete group.

Fixed state: group does not exist.

Fixable state: group exists.

This function is not exported.

This function is idempotent (repeated invocations with same arguments has the same effect as single invocation). This function supports transactions.

Arguments ('*' denotes required arguments):

  • etc_dir => str (default: "/etc")

    Location of passwd files.

  • group => str

    Group name.

Special arguments:

Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)

setup_unix_group

Usage:

 setup_unix_group(%args) -> [status, msg, result, meta]

Setup Unix group (existence).

On do, will create Unix group if not already exists. The created GID will be returned in the result ({gid => GID}). If should_already_exist is set to true, won't create but only require that group already exists. If should_exist is set to false, will delete existing group instead of creating it.

On undo, will delete Unix group previously created.

On redo, will recreate the Unix group with the same GID.

This function is not exported by default, but exportable.

  • group => str

    Group name.

  • max_new_gid => int (default: 65534)

    Passed to Unix::Passwd::File's max_new_gid.

  • min_new_gid => int (default: 1000)

    Specify range for new GID.

    If a free GID between min_gid and max_gid is not available, an error is returned.

    Passed to Unix::Passwd::File's min_new_gid.

  • new_gid => int

    Add with specified GID.

    If not specified, will search an unused GID from min_new_gid to max_new_gid.

    If specified, will accept non-unique GID (that which has been used by other group).

  • should_already_exist => bool

    Whether group should already exist.

  • should_exist => bool (default: 1)

    Whether group should exist.
