+.SH NAME
+bg
+\(em run jobs in the background
+.SH SYNOPSIS
+.LP
+.nf
+bg \fB[\fIjob_id\fR...\fB]\fR
+.fi
+.SH DESCRIPTION
+If job control is enabled (see the description of
+.IR set
+.BR \-m ),
+the
+.IR bg
+utility shall resume suspended jobs from the current environment (see
+.IR "Section 2.12" ", " "Shell Execution Environment")
+by running them as background jobs. If the job specified by
+.IR job_id
+is already a running background job, the
+.IR bg
+utility shall have no effect and shall exit successfully.
+.P
+Using
+.IR bg
+to place a job into the background shall cause its process ID to become
+``known in the current shell execution environment'', as if it had been
+started as an asynchronous list; see
+.IR "Section 2.9.3.1" ", " "Examples".
+.SH OPTIONS
+None.
+.SH OPERANDS
+The following operand shall be supported:
+.IP "\fIjob_id\fR" 10
+Specify the job to be resumed as a background job. If no
+.IR job_id
+operand is given, the most recently suspended job shall be used. The
+format of
+.IR job_id
+is described in the Base Definitions volume of POSIX.1\(hy2017,
+.IR "Section 3.204" ", " "Job Control Job ID".
+.SH STDIN
+Not used.
+.SH "INPUT FILES"
+None.
+.SH "ENVIRONMENT VARIABLES"
+The following environment variables shall affect the execution of
+.IR bg :
+.IP "\fILANG\fP" 10
+Provide a default value for the internationalization variables that are
+unset or null. (See the Base Definitions volume of POSIX.1\(hy2017,
+.IR "Section 8.2" ", " "Internationalization Variables"
+for the precedence of internationalization variables used to determine
+the values of locale categories.)
+.IP "\fILC_ALL\fP" 10
+If set to a non-empty string value, override the values of all the
+other internationalization variables.
+.IP "\fILC_CTYPE\fP" 10
+Determine the locale for the interpretation of sequences of bytes of
+text data as characters (for example, single-byte as opposed to
+multi-byte characters in arguments).
+.IP "\fILC_MESSAGES\fP" 10
+.br
+Determine the locale that should be used to affect the format and
+contents of diagnostic messages written to standard error.
+.IP "\fINLSPATH\fP" 10
+Determine the location of message catalogs for the processing of
+.IR LC_MESSAGES .
+.SH "ASYNCHRONOUS EVENTS"
+Default.
+.SH STDOUT
+The output of
+.IR bg
+shall consist of a line in the format:
+.sp
+.RS 4
+.nf
+
+"[%d] %s\en", <\fIjob-number\fR>, <\fIcommand\fR>
+.fi
+.P
+.RE
+.P
+where the fields are as follows:
+.IP "<\fIjob-number\fR>" 10
+A number that can be used to identify the job to the
+.IR wait ,
+.IR fg ,
+and
+.IR kill
+utilities. Using these utilities, the job can be identified by
+prefixing the job number with
+.BR '%' .
+.IP "<\fIcommand\fR>" 10
+The associated command that was given to the shell.
+.SH STDERR
+The standard error shall be used only for diagnostic messages.
+.SH "OUTPUT FILES"
+None.
+.SH "EXTENDED DESCRIPTION"
+None.
+.SH "EXIT STATUS"
+The following exit values shall be returned:
+.IP "\00" 6
+Successful completion.
+.IP >0 6
+An error occurred.
+.SH "CONSEQUENCES OF ERRORS"
+If job control is disabled, the
+.IR bg
+utility shall exit with an error and no job shall be placed in the
+background.
+.LP
+.IR "The following sections are informative."
+.SH "APPLICATION USAGE"
+A job is generally suspended by typing the SUSP character
+(<control>\(hyZ on most systems); see the Base Definitions volume of POSIX.1\(hy2017,
+.IR "Chapter 11" ", " "General Terminal Interface".
+At that point,
+.IR bg
+can put the job into the background. This is most effective when the
+job is expecting no terminal input and its output has been redirected
+to non-terminal files. A background job can be forced to stop when it
+has terminal output by issuing the command:
+.sp
+.RS 4
+.nf
+
+stty tostop
+.fi
+.P
+.RE
+.P
+A background job can be stopped with the command:
+.sp
+.RS 4
+.nf
+
+kill -s stop \fIjob ID\fR
+.fi
+.P
+.RE
+.P
+The
+.IR bg
+utility does not work as expected when it is operating in its own
+utility execution environment because that environment has no suspended
+jobs. In the following examples:
+.sp
+.RS 4
+.nf
+
+\&... | xargs bg
+(bg)
+.fi
+.P
+.RE
+.P
+each
+.IR bg
+operates in a different environment and does not share its parent
+shell's understanding of jobs. For this reason,
+.IR bg
+is generally implemented as a shell regular built-in.
+.SH EXAMPLES
+None.
+.SH RATIONALE
+The extensions to the shell specified in this volume of POSIX.1\(hy2017 have mostly been based
+on features provided by the KornShell. The job control features
+provided by
+.IR bg ,
+.IR fg ,
+and
+.IR jobs
+are also based on the KornShell. The standard developers examined the
+characteristics of the C shell versions of these utilities and found
+that differences exist. Despite widespread use of the C shell, the
+KornShell versions were selected for this volume of POSIX.1\(hy2017 to maintain a degree of
+uniformity with the rest of the KornShell features selected (such as
+the very popular command line editing features).
+.P
+The
+.IR bg
+utility is expected to wrap its output if the output exceeds the number
+of display columns.
+.SH "FUTURE DIRECTIONS"
+None.
