In a variable so that I can use it in a later computation. This is all a huge script that uses ssh to do a bunch of remote work. I need a single remote invocation to print some junk to stdout, and start a long running process that I will wait on. The goal is to pull the junk out of stdout, and on the basis of that, figure out what data I will send the long running process (it is listening on a seperate port).

fg(1)							      General Commands Manual							     fg(1)

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. SEE ALSO
Commands: bg(1), csh(1), jobs(1), kill(1), ksh(1), sh(1p), wait(1) Standards: standards(5) fg(1)
