Excerpt from:   bashref.info   >>   Bash Variables   >>   BASH_XTRACEFD variable

BASH_XTRACEFD

If set to an integer corresponding to a valid file descriptor, Bash
will write the trace output generated when 'set -x' is enabled to
that file descriptor. This allows tracing output to be separated
from diagnostic and error messages. The file descriptor is closed
when 'BASH_XTRACEFD' is unset or assigned a new value. Unsetting
'BASH_XTRACEFD' or assigning it the empty string causes the trace
output to be sent to the standard error. Note that setting
'BASH_XTRACEFD' to 2 (the standard error file descriptor) and then
unsetting it will result in the standard error being closed.

Model-Matrix

Daily updated index of the presence and value of this variable for each model. Last update: 2024-03-20 06:41 GMT.
Showing all models using this variable. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom) label in the Model column shows which CPU is meant for models with multiple Linux instances.
Note that this list is merged from Firmware-Probes of all known AVM firmware for a model, including Recovery.exe and Labor-Files.
If the 'Value' column contains '<comp>' the variable is computed at runtime. '<empty>' means the variable is present but empty (rare).
Multiple values typically show a conditional static assignment or different values in different firmware.
