NAME
nice - invoke a command with an altered scheduling priority
SYNOPSIS
/usr/bin/nice [-increment | -n increment | --adjustment=increment]
command [argument]...
/usr/bin/nice
/usr/xpg4/bin/nice [-increment | -n increment] command
[argument]...
csh Builtin
nice [-increment | +increment] [command]
DESCRIPTION
The nice utility invokes command, requesting that it be run with a dif‐
ferent system scheduling priority. The priocntl(1) command is a more
general interface to scheduler functions.
The invoking process (generally the user's shell) must be in a schedul‐
ing class that supports nice.
If the C shell (see csh(1)) is used, the csh built-in version of nice
will be invoked unless the full path of the nice utility is specified.
See csh Builtin below.
/usr/bin/nice
If nice executes commands with arguments, it uses the default shell
/usr/bin/sh (see sh(1)).
/usr/xpg4/bin/nice
If nice executes commands with arguments, it uses /usr/xpg4/bin/sh (see
ksh88(1)).
csh Builtin
nice is also a csh built-in command with behavior different from the
utility versions. See csh(1) for description.
OPTIONS
With no options, the nice utility reports the nice level of the current
process.
The following options are supported:
-increment | -n increment |
--adjustment=increment
increment is a positive or negative decimal integer that has the
same effect on the execution of the utility as if the utility had
called the nice() function with the numeric value of the increment
option-argument. See nice(2). nice() errors, other than EINVAL, are
ignored. If not specified, an increment of 10 is assumed.
Running commands with priority higher than normal by using a nega‐
tive increment such as -10 requires the {PRIV_PROC_PRIOCNTL} privi‐
lege. A negative increment assigned by an unprivileged user is
ignored.
--help
Displays a usage message and exits.
OPERANDS
The following operands are supported:
command The name of a command that is to be invoked. If command
names any of the special built-in utilities (see
shell_builtins(1)), the results are undefined.
argument Any string to be supplied as an argument when invoking com‐
mand.
ENVIRONMENT VARIABLES
See environ(7) for descriptions of the following environment variables
that affect the execution of nice: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES,
PATH, and NLSPATH.
EXIT STATUS
If command is invoked, the exit status of nice will be the exit status
of command. Otherwise, nice will exit with one of the following values:
1-125 An error occurred.
126 command was found but could not be invoked.
127 command could not be found.

HISTORY
Support for the --adjustment and --help options, as well as for running
nice with no options to print the current level, were added to the
Solaris nice command in Oracle Solaris 11.4.0.
The -n option and /usr/xpg4/bin/nice command were added to Solaris in
Solaris 2.5.
The nice command has been included in all versions of SunOS & Solaris.
