The errors are going to stderr (2) Normal output goes to stdout (1)
This makes both streams go to ../engine_output.txt
It won't make both streams go to the file becasue 2 is duplicated to 1 before 1 is redirected to the file. As a result stdout goes to the file and stderr goes to stdout.

/bin/sh -c " . /etc/timezone; exec /test"

bdiff
bdiff(1) User Commands bdiff(1)NAME
bdiff - big diff
SYNOPSIS
bdiff filename1 filename2 [n] [-s]
DESCRIPTION
bdiff is used in a manner analogous to diff to find which lines in filename1 and filename2 must be changed to bring the files into agree-
ment. Its purpose is to allow processing of files too large for diff. If filename1 (filename2) is -, the standard input is read.
bdiff ignores lines common to the beginning of both files, splits the remainder of each file into n-line segments, and invokes diff on cor-
responding segments. If both optional arguments are specified, they must appear in the order indicated above.
The output of bdiff is exactly that of diff, with line numbers adjusted to account for the segmenting of the files (that is, to make it
look as if the files had been processed whole). Note: Because of the segmenting of the files, bdiff does not necessarily find a smallest
sufficient set of file differences.
OPTIONS
n The number of line segments. The value of n is 3500 by default. If the optional third argument is given and it is numeric, it is
used as the value for n. This is useful in those cases in which 3500-line segments are too large for diff, causing it to fail.
-s Specifies that no diagnostics are to be printed by bdiff (silent option). Note: However, this does not suppress possible diagnos-
tic messages from diff, which bdiff calls.
USAGE
See largefile(5) for the description of the behavior of bdiff when encountering files greater than or equal to 2 Gbyte ( 2**31 bytes).
