Add the directory containing the tools to your shell search path

The following sections assume that the directory into which you will install the cross-development tools (/usr/local/rtems/rtems-4.9/bin) is on your shell search path. For shells like sh, bash, zsh and ksh you can to this with

PATH="$PATH:/usr/local/rtems/rtems-4.9/bin"

For shells like csh and tcsh you can

set path = ( $path /usr/local/rtems/rtems-4.9/bin )
