NAME

       bg - Runs jobs in the background

SYNOPSIS

       bg [job_id...]

									  Note

       The  C shell  has a built-in version of the bg command.	If you are using the C shell, and want to guarantee that you are using the command
       described here, you must specify the full path /usr/bin/bg.  See the csh(1) reference page for a description of the built-in command.

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       bg:  XCU5.0

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

OPTIONS

       None

OPERANDS

       Specifies the job to be resumed as a background job. If no job_id operand is given, the most recently suspended job is used. The format	of
       job_id is described in the Jobs section of the ksh(1) reference page.

DESCRIPTION

       If job control is enabled (see the description of set -m in the ksh(1) reference page), the bg utility resumes suspended jobs from the cur-
       rent environment by running them as background jobs.  If the job specified by job_id is a job already running in  the  background,  the	bg
       utility has no effect and will exit successfully.

       Using  bg  to  place a job into the background causes its process ID to become "known in the current shell execution environment", as if it
       had been started as an asynchronous list.  See the Jobs section of the ksh(1) reference page.

RESTRICTIONS

       If job control is disabled, the bg utility exits with an error and no job is placed in the background.  The bg utility  does  not  work	as
       expected when it is operating in its own utility execution environment because that environment has no suspended jobs.

EXIT STATUS

       The following exit values are returned: Successful completion.  An error occurred.

ENVIRONMENT VARIABLES

       The  following  environment  variables affect the execution of bg: Provides a default value for the internationalization variables that are
       unset or null. If LANG is unset or null, the corresponding value from the default locale is used.  If any of the internationalization vari-
       ables  contain  an  invalid setting, the utility behaves as if none of the variables had been defined.  If set to a non-empty string value,
       overrides the values of all the other internationalization variables.  Determines the locale for the interpretation of sequences  of  bytes
       of  text  data  as  characters  (for  example, single-byte as opposed to multibyte characters in arguments).  Determines the locale used to
       affect the format and contents of diagnostic messages written to standard error.  Determines the location of  message  catalogues  for  the
       processing of LC_MESSAGES.
