Target-side command-line utilities

QNX SDP8.0Migrating to QNX OS 8.0Developer

Toybox

A number of common command line utilities that run on QNX OS targets and were previously provided as a QNX version have been replaced with equivalent toybox versions. For a full list, see the QNX Software Development Platform 8.0: Discontinuation Notice.

To enable toybox utilities, in the appropriate buildfile, add links to both toybox and each individual command you want to enable. For detailed information and examples, see the toybox entry in the Utilities Reference.

For information on other command line tools that have been deprecated or removed for this release, see the QNX Software Development Platform 8.0: Discontinuation Notice.

For more information on toybox, go to http://landley.net/toybox/about.html.

mount_ifs, mount

The mount_ifs utility no longer daemonizes when mounting an image file system (IFS). The -b option, which controlled the timing of the mount_ifs utility's daemonization, is now deprecated.

The mount_ifs utility now supports the mounting of an in-memory IFS via the -o option, which is used to specify offset and size mount options.

The mount utility now invokes the mount_ifs utility to mount an in-memory IFS. If you used mount for this action on a QNX OS 7.1 or earlier system, you need to add the mount_ifs utility to your QNX system image.
