% tpm2(1) tpm2-tools | General Commands Manual

# NAME

**tpm2**(1) - A single small executable that combines the various tpm2-tools
much like a BusyBox that provides a fairly complete environment for any small or
embedded system.

# SYNOPSIS

**tpm2** [*OPTIONS*] [*ARGUMENTS*]

# DESCRIPTION

**tpm2**(1) - To ease installation of tpm2-tools in initrd or embedded systems
where size-optimization and limited resources are important, it is convenient to
have a single executable that can dispatch the various TPM2 functionalities
specified by the argument which is one of the available tool names.

The options and arguments that follow are either the **common options** or those
specific to the **tool name**.

It is important to note that individual tools with prefix **tpm2_** can still be
invoked, however, they are now soft-linked to this **tpm2** executable. And so
unlike BusyBox, full functionality of the individual tools is available in the
executable. For example: **tpm2_getrandom 8** can alternatively be specified as
**tpm2 getrandom 8**.
