NAME Sah::Schemas::Unix - Various Sah schemas for Unix VERSION This document describes version 0.021 of Sah::Schemas::Unix (from Perl distribution Sah-Schemas-Unix), released on 2022-09-08. SAH SCHEMAS The following schemas are included in this distribution: * unix::dirname Directory name (with optional path) on a Unix system. This is just a convenient alias for dirname::unix. * unix::filename File name (with optional path) on a Unix system. This is just a convenient alias for filename::unix. * unix::gid Group identifier (GID). Note that this schema does not check whether the GID exists (has record in the user database e.g. "/etc/group"). To do that, use the "unix::gid::exists" schema. * unix::gid::exists Group identifier (GID) that has to exist on the system. Existing means having a group name associated with this GID, i.e. "getgrgid" returns a record. Support coercion from an existing group name. * unix::groupname Unix group name. The checking follows POSIX rules: does not begin with a hyphen and only contains [A-Za-z0-9._-]. The above rule allows integers like 1234, which can be confused with GID, so this schema disallows pure integers. The maximum length is 32 following libc6's limit. Note that this schema does not check whether the group name exists (has record in the user database e.g. "/etc/group"). To do that, use the "unix::groupname::exists" schema. * unix::groupname::exists Unix group name that must exist on the system. Support coercion from GID. * unix::pathname Path name (filename or dirname) on a Unix system. This is just a convenient alias for pathname::unix. * unix::pid Process identifier (PID). * unix::signal Unix signal name (e.g. TERM or KILL) or number (9 or 15). * unix::uid User identifier (UID). Note that this schema does not check whether the UID exists (has record in the user database e.g. "/etc/passwd"). To do that, use the "unix::uid::exists" schema. * unix::uid::exists User identifier (UID) that has to exist (has associated username) on the system. Existing means having a user name associated with this UID, i.e. "getpwuid" returns a record. Support coercion from an existing user name. * unix::username Unix account name. The checking follows POSIX rules: does not begin with a hyphen and only contains [A-Za-z0-9._-]. The above rule allows integers like 1234, which can be confused with UID, so this schema disallows pure integers. The maximum length is 32 following libc6's limit. Note that this schema does not check whether the user name exists (has record in the user database e.g. "/etc/group"). To do that, use the "unix::username::exists" schema. * unix::username::exists Unix user name that must exist on the system. Support coercion from UID.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me. COPYRIGHT AND LICENSE This software is copyright (c) 2022, 2020, 2019 by perlancar .
