kdb_env(1)

Usage

env

set environment-variable=value

Overview

The kernel debugger contains an environment which contains a series of name-value pairs. Some environment variables are known to the various kernel debugger commands and have specific meaning to the command; such are enumerated on the respective reference material.

Arbitrary environment variables may be created and used with many commands (those which require an address-expression).

The env command is used to display the current environment.

The set command is used to alter an existing environment variable or establish a new environment variable.

Limitations

There is a compile-time limit of 33 environment variables.

There is a compile-time limit of 512 bytes (KDB_ENVBUFSIZE) of heap space available for new environment variables and for environment variables changed from their compile-time values.

Environment

These commands explicitly manipulate the environment.

SMP considerations

None.

User settings

You can include "set" commands in kdb/kdb_cmds (see kdb.mm) to define your environment variables at kernel startup.

Examples

`env`	Display current environment settings.
`set IDCOUNT=100`	Set the number of lines to display for the `id` command to the value 100.
