About This Reference

The Utilities Reference describes the utilities, manager processes, and configuration files included with the QNX Neutrino operating system. This reference is intended for everyone from end-users to system administrators.

Here are some links to help you find what you need:

A ¦ B ¦ C ¦ D ¦ E ¦ F ¦ G ¦ H ¦ I ¦ J ¦ K ¦ L ¦ M ¦ N ¦ O ¦ P ¦ Q ¦ R ¦ S ¦ T ¦ U ¦ V ¦ W ¦ X ¦ Y ¦ Z

Your system might not include all of the things that this reference describes, depending on what software you've installed. For example, some utilities are included in the QNX Momentics development suite, and others are included in a specific Board Support Package (BSP) or Technology Development Kit (TDK).

The Utilities Reference also contains:

a section on the Utility Conventions used here
a Utilities Summary that arranges the entries into categories:
- Configuration files
- Managers -- special processes that manage resources
- Utilities
a description of the Commonly Used Environment Variables
a discussion on Selecting the Target System for GNU utilities
a list of relevant Third-Party Copyright Notices
a Glossary of QNX Neutrino terminology.

What's new in QNX Neutrino Core OS 6.3.2

New content

aps: Manage adaptive scheduler partitions

Changed content

devb-ram

Added address, blksize, and nodinit to the list of ram options.

mkifs

Now includes the module attribute for loading optional modules into procnto.

on

Now includes -C, -i, and -R options for specifying the runmask for the new process.

pidin

Now includes H, h, i, and o formatting codes, and extsched, fds, regs, sched, and threads arguments.

procnto

Now includes -m and -c options.

slay

Now includes -C, -i, and -R options for manipulating the runmask, and -T for identifying the thread that you want to send a signal to or whose runmask or priority you want to change. Also includes -m option to restrict the match.

-P without -T now affects all threads in the specified proccess or processes. Previously it affected only thread 1.

This utility now matches process IDs or names; you can use the new -m option to limit which it matches.

startup-*

Now include a -F option to control the flags field in the cpuinfo section of the system page.

qconfig

Added the -a, -b, and -p options.

Errata

dcheck: Corrected the name of the .bad_blks file.
passwd: The second field of entries in the /etc/passwd file is an x. It represents the group password, which Neutrino doesn't support.
psin: A suffix of s appears beside file descriptors that were opened as side channels.

What's new in 6.3.0 Service Pack 2

qcc: The -M option is deprecated as of QNX Momentics 6.3.0 Service Pack 2. The next release will use -M for generating Makefile dependencies.
The -w9 option's behavior specifically documented, with additional options necessary to report all warnings.
qconn: Added more description to the qconn_prio= option to prevent errors when the system is under heavy load.
sendnto: Documented -b option.
su: Documented - userid argument.
tracelogger: Now accepts control commands through its device, devctl() and pulses, and has a new option (-c).

usemsg: %1> and %2> macros fixed (were previously documented as %0> and %1>).
usemsg also uses objcopy by default instead of ldrel.

Errata

io-blk.so: If you don't specify a full path for the device in the automount option, io-blk.so uses the value of its devdir option as a prefix.
