This is about getting all output to stderr and stdout localized. Nothing to do with redirecting output to a file (there already are some interesting threads about that issue on this forum).

In bash, I need to send the STDOUT and STDERR from a command to one file, and then just STDERR to another file. Doing one or the other using redirects is easy, but trying to do both at once is a bit tricky. Anyone have any ideas? (9 Replies)

bg(1) General Commands Manual bg(1)
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.
