NAME

Sah::Schemas::Unix - Various Sah schemas for Unix

VERSION

This document describes version 0.018 of Sah::Schemas::Unix (from Perl distribution Sah-Schemas-Unix), released on 2021-07-29.

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).

• 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.

• unix::local_gid

  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::local_groupname

  Unix group name that must exist on the system.

  Support coercion from GID.

• unix::local_uid

  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::local_username

  Unix user name that must exist on the system.

  Support coercion from UID.

• 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).

• 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.
