sharesec

Given that sharesec is not a standard Linux command, a precise synopsis does not exist. However, based on its inferred purpose, a hypothetical synopsis might resemble commands used for security management:

sharesec [options] <share_name>
sharesec --list [options]
sharesec --get <share_name>
sharesec --set <share_name> [options] [<user>] [<permissions>]
sharesec --add <share_name> <user> <permissions>
sharesec --remove <share_name> <user>

<share_name>
    The name of the network share to operate on. (Hypothetical)

--list
    Lists all configured network shares and their basic security attributes. (Hypothetical)

--get
    Displays the detailed security settings (e.g., users, groups, permissions) for a specified share. (Hypothetical)

--set
    Modifies or sets new security attributes for a specified share. Requires additional parameters like user and permissions. (Hypothetical)

--add
    Adds a new user or group with specified permissions to a share's access list. (Hypothetical)

--remove
    Removes a user or group's access entry from a specified share. (Hypothetical)

--user <username>
    Specifies the user for whom to apply or query security settings. (Hypothetical)

--group <groupname>
    Specifies the group for whom to apply or query security settings. (Hypothetical)

--perms <permissions>
    Defines the access permissions (e.g., read, write, execute, or numeric modes) for the specified user or group. (Hypothetical)

--verbose
    Provides more detailed output regarding the command execution or share settings. (Hypothetical)

The sharesec command is not a standard utility found in typical Linux distributions. Its name strongly suggests a function related to managing 'share security,' which would involve controlling access permissions, users, and groups for network shares (e.g., Samba, NFS). If such a command existed as a standalone tool, it would likely provide functionalities for viewing, adding, modifying, or removing security configurations on shared directories or resources.

In standard Linux environments, share security is typically managed through a combination of file system permissions (chmod, chown), Access Control Lists (setfacl), and specific configuration files for network sharing services like Samba (/etc/samba/smb.conf) or NFS (/etc/exports). It is possible that sharesec could be a custom script, an alias, or a command specific to a proprietary system or appliance (like a Network Attached Storage device) that simplifies these underlying configurations.

The sharesec command is not a standard component of most Linux distributions. Information provided here is largely based on inference from its name and common network share management practices. If you encountered this command, it is likely part of a specific appliance's operating system (e.g., a NAS device's custom Linux-based OS), a bespoke internal utility, or a script developed for a particular environment. Its availability, syntax, and functionality would be entirely dependent on that specific context and not generally applicable across all Linux systems.

In standard Linux, managing security for network shares (Samba, NFS) involves several layers:

1. File System Permissions: Basic Linux permissions (owner, group, others) and extended permissions (setuid, setgid, sticky bit) managed by chmod and chown.
2. Access Control Lists (ACLs): Granular permissions beyond standard owner/group/other, allowing specific permissions for multiple users and groups. Managed by setfacl and getfacl.
3. Service-Specific Configurations: For Samba, access is controlled via smb.conf settings (e.g., 'valid users', 'read list', 'write list', 'create mask', 'directory mask', 'security = user/domain/ads'). For NFS, access is controlled via /etc/exports settings (e.g., host restrictions, 'rw', 'ro', 'sync', 'no_root_squash').
4. User and Group Management: Users and groups must exist on the system (or be authenticated via a directory service like LDAP/AD) for permissions to be effective.

As sharesec is not a standard Linux command, there is no documented public history of its development or widespread usage within the general Linux ecosystem. It does not appear in historical Unix or Linux command archives. If it exists, its history would be confined to the development and evolution of the specific product or system it is part of, which is outside the scope of general Linux command documentation.
