Overview
Change only the metadata you need
Change only the metadata you mean to change: permissions, date or time, access time and modification time can be selected deliberately.
Syntax
mod <path> [-0755|-m 0755] [-YYYYMMDD] [-HHMMSS] [-o|-s]Reference
mod <path> -0755set octal permissions directly
mod <path> -m 0755set permissions in UNIX mode format through the mode option
mod <path> -20251225set the date
mod <path> -121008set the time in HHMMSS format
mod <path> -20251225 -121008set the date and time
mod <path> ... -ochange only the access time
mod <path> ... -schange only the modification time
Permissions
The short -0755 form and -m 0755 describe the same UNIX permission value. They are kept as two explicit syntaxes so users can choose compact terminal input or a conventional mode option.
Timestamps
Date and time can be supplied together or separately. Without -o or -s, timestamp changes apply to both access and modification time. -o restricts the change to access time; -s restricts it to modification time. ctime is controlled by the filesystem and cannot be set directly.

Run the prepared examples directly on the page. Their results are prebuilt and shown in the browser; no terminal command is executed on the server.
Install and manage
Install the current compatible version. Choose Base for the complete feature set or Minimum for the reduced package; use upgrade to update a module that is already installed.
Base and Minimum are two packages of the same current module release, not separate command versions.
Minimum package
Install the reduced package. Local reference is omitted;
install mod -mExact public version
Install exactly this published version.
install mod -v 1.1.3Check or update
Ask upgrade to check compatibility and replace the installed block only when needed.
upgrade modRemove module
Remove the extension block while leaving the core and unrelated modules intact.

Examples are copyable command lines, not actions executed by this website. Review paths, permissions and destructive flags before running them on a real project.

Commands in the public documentation use this directory for disposable copies,
archives, uploads and files created during examples. Review destructive commands
before running them and restore the sandbox from the release package when needed.
