  • This section describes the additional commands available within the RTEMS Development Environment. Although some of these commands are of general use, most are included to provide some capability necessary to perform a required function in the development of the RTEMS executive, one of its support components, or an RTEMS based application. The commands have been classified into the following categories for clarity:

    Some of the commands are implemented as C programs. However, most commands are implemented as Bourne shell scripts. Even if the current user has selected a different shell, the scripts will automatically invoke the Bourne shell during their execution lifetime.

    The commands are presented in UNIX manual page style for compatibility and convenience. A standard set of paragraph headers were used for all of the command descriptions. If a section contained no data, the paragraph header was omitted to conserve space. Each of the permissible paragraph headers and their contents are described below:

    describes the command syntax
    a full description of the command
    describes each of the permissible options for the command
    lists any special noteworthy comments about the command
    describes all environment variables utilized by the command
    illustrates the use of the command with specific examples
    provides a list of major files that the command references
    lists any relevant commands which can be consulted

    Most environment variables referenced by the commands are defined for the RTEMS Development Environment during the login procedure. During login, the user selects a default RTEMS environment through the use of the Modules package. This tool effectively sets the environment variables to provide a consistent development environment for a specific user. Additional environment variables within the RTEMS environment were set by the system administrator during installation. When specifying paths, a command description makes use of these environment variables.

    When referencing other commands in the SEE ALSO paragraph, the following notation is used: command(code). Where command is the name of a related command, and code is a section number. Valid section numbers are as follows:

    Section 1 of the standard UNIX documentation
    Section 1 of the GNU documentation
    a manual page from this document, the RTEMS Development Environment Guide

    For example, ls(1) means see the standard ls command in section 1 of the UNIX documentation. gcc020(1G) means see the description of gcc020 in section 1 of the GNU documentation.
