NAME
       fg - Runs jobs in the foreground

SYNOPSIS
       fg [job_id...]

									  Note

       The  C shell  has a built-in version of the fg 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/fg.  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:

       fg:  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 run as a foreground job. If no job_id operand is given, the job_id for the job that was	most  recently	suspended,
       placed in the background or run as a background 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 fg utility moves a background job from the cur-
       rent environment into the foreground.

       Using  fg  to  place a job into the foreground removes its process ID from the list of those "known in the current shell execution environ-
       ment"; see the Jobs section of the ksh(1) reference page.

RESTRICTIONS
       If job control is disabled, the fg utility exits with an error and no job is placed in the foreground.  The fg utility  does  not  work	as
       expected when it is operating in its own utility execution environment because that environment has no applicable jobs to manipulate.

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

ENVIRONMENT VARIABLES
       The  following  environment  variables affect the execution of fg: 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.
