NAME

       nice - invoke a command with an altered scheduling priority

SYNOPSIS

       /usr/bin/nice [-increment | -n increment] command
	    [argument]...

       /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 different 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 scheduling class that supports nice.

       If the C shell (see csh(1)) is used, the full path of the command must be specified. Otherwise, the csh built-in version of  nice  will	be
       invoked. 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 ksh(1)).

   csh Builtin
       nice is also a csh built-in command with behavior different from the utility versions.  See csh(1) for description.

OPTIONS

       The following options are supported:

       -increment | -n 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.

				    The  super-user may run commands with priority higher than normal by using a negative increment such as -10. A
				    negative increment assigned by an unprivileged user is ignored.

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 command.

ENVIRONMENT VARIABLES

       See  environ(5)	for descriptions of the following environment variables that affect the execution of nice: LANG, LC_ALL, LC_CTYPE, LC_MES-
       SAGES, 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 val-
       ues:

       1-125	An error occurred.

       126	command was found but could not be invoked.

       127	command could not be found.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:
