Portability
When you change the priority of a process group, the priority of all processes in
that group are changed.
If the string -- appears in the arguments, renice does not interpret it as the end of
command-line arguments. This is an exception to the usual POSIX syntax rules.
–g Treats all following IDs (or just pgrps in the obsolescent versions) as
process group IDs.
–n increment
Adjusts the system scheduling priority of the specified processes by
increment. Positive increments lower the priority while negative increments
result in a higher priority.
Note: Negative increments may require appropriate privileges.
–p Treats all following IDs (or just pids in the obsolescent versions) as process
IDs.
–u Treats all following IDs (or just users in the obsolescent versions) as either
user names or numeric user IDs.
priority A number that indicates an absolute priority value (higher numbers reflect
higher priorities).
If no –p, –g, or –u option appears on the command line, renice assumes –p.
renice uses the following localization environment variables:
v LANG
v LC_ALL
v LC_CTYPE
v LC_MESSAGES
v NLSPATH
See Appendix F for more information.
0 Successful completion
1 Failure due to one of the following:
v Incorrect command-line argument
v The wrong number of command-line arguments
v A priority that is outside the range
v An incorrect priority argument
v An incorrect ID argument
v Missing arguments following one of the options
2 Failure because the system does not recognize the ID in a –u option
POSIX.2 User Portability Extension, UNIX systems.
POSIX considers all but the first form of the renice command to be obsolescent.
