Ok it sort of works now, but theres a problem, here what i did
The output is sorta correct, i gave the input command to be ls, the output was
my_prog.c
my_prog
abc
ñà·
EÉ÷·8É÷·*à·
0
The zero come up since ls was successfull, but i dont understand why the files in the directory came up line by line and not all in one line like how normally doing ls would result in, also theres some gibberish lines after the ls command results, why did that show up? Am I missing a \0 anywhere or something?
Also i tried giving a command that would fail like cd ffg, and the WEXITSTATUS number came out to be 2, so what really are the possible outcomes for WEXITSTATUS? i only know so far 0 and 2, shouldnt it be -1 instead of 2?

bdiff(1) General Commands Manual bdiff(1)
Name
bdiff - big file differential comparator
Syntax
bdiff file1 file2 [n] [-s]
Description
The command is used to find lines that must be changed in two files to bring them into agreement. Its purpose is to allow processing of
files that are too large for
The command ignores lines common to the beginning of both files, splits the remainder of each file into n-line segments, and invokes upon
corresponding segments. The value of n is 3500 by default. If the optional third argument is given and if 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 causing it to fail.
The output of the command is the same as the output of the command: line numbers are adjusted to account for the segmenting of the files to
make it look as if the files had been processed whole. Note that because of the segmenting of the files, does not necessarily find the
smallest sufficient set of file differences.
If either file1 or file2 is -, the standard input is read. The optional -s (silent) argument specifies that no diagnostics are to be
printed by However, this does not suppress possible exclamations by If both optional arguments are specified, they must appear in the order
indicated above.
Options
-s Suppresses normal diagnostic messages.
Diagnostics
