Yeah, I know, sorry the code is so huge, I guess I had to post the whole code so the mods don't come down on me for not filling out the whole thread template, but anyway... I wish I had time to simplify the code, now I'm just trying to get this thing going. I changed the code to this (just including the problem area in the "create_command_process" function):
When I run it with "ls | wc", absolute NO output to the shell console comes back (even though it's writing stuff to my logfile). I will work on this some more, but I don't know if this means it's working now? Aren't I like supposed to get a set of numbers back for "ls | wc"? (running it in shell spits out "16 16 150" in my current folder). Then again, the assignment description says this, and I quote:
" The standard output stream is used and used only for printing command execution results. "
So I take this to mean I shouldn't have to worry enough about it printing anything straight to the console?

Oh, really? I didn't know that. I just heard that any non-zero number fed into an exit() call indicated failure so I use 666 to be a wise guy for obvious reasons, bahahaha. I'll change it, though, to be something in that valid range. Thanks.
I've got a c++ program that works fine on Linux, compiles on Solaris fine with g++, but will not write to a fstream correctly in a class object.
And I've run into numerous other bugs in the disk management.

echo "ERROR!"

In the above script, ] is supposed to test the exit code of "grep abc... (3 Replies)

Hi,
I have Solaris-10 OS on T5220. Both local disks were mirrored under SVM. Somehow when one disk gone bad (c0t1d0), other disk (c0t0d0) also got lot of bad block.

OD(1) FSF OD(1)NAME
od - dump files in octal and other formats
SYNOPSIS
od [OPTION]... [FILE]...
od --traditional [FILE] [[+]OFFSET [[+]LABEL]]
DESCRIPTION
Write an unambiguous representation, octal bytes by default, of FILE to standard output. With more than one FILE argument, concatenate
them in the listed order to form the input. With no FILE, or when FILE is -, read standard input.
All arguments to long options are mandatory for short options.
-A, --address-radix=RADIX
decide how file offsets are printed
-j, --skip-bytes=BYTES
skip BYTES input bytes first
-N, --read-bytes=BYTES
limit dump to BYTES input bytes
-s, --strings[=BYTES]
output strings of at least BYTES graphic chars
-t, --format=TYPE
select output format or formats
-v, --output-duplicates
do not use * to mark line suppression
-w, --width[=BYTES]
output BYTES bytes per output line
--traditional
accept arguments in traditional form
--help display this help and exit
--version
output version information and exit
Traditional format specifications may be intermixed; they accumulate:
-a same as -t a, select named characters
-b same as -t oC, select octal bytes
-c same as -t c, select ASCII characters or backslash escapes
-d same as -t u2, select unsigned decimal shorts
-f same as -t fF, select floats
-h same as -t x2, select hexadecimal shorts
-i same as -t d2, select decimal shorts
-l same as -t d4, select decimal longs
-o same as -t o2, select octal shorts
-x same as -t x2, select hexadecimal shorts
For older syntax (second call format), OFFSET means -j OFFSET. LABEL is the pseudo-address at first byte printed, incremented when dump is
progressing. For OFFSET and LABEL, a 0x or 0X prefix indicates hexadecimal, suffixes may be . for octal and b for multiply by 512.
TYPE is made up of one or more of these specifications:
a named character
c ASCII character or backslash escape
d[SIZE]
signed decimal, SIZE bytes per integer
f[SIZE]
floating point, SIZE bytes per integer
o[SIZE]
octal, SIZE bytes per integer
u[SIZE]
unsigned decimal, SIZE bytes per integer
x[SIZE]
hexadecimal, SIZE bytes per integer
SIZE is a number. For TYPE in doux, SIZE may also be C for sizeof(char), S for sizeof(short), I for sizeof(int) or L for sizeof(long). If
TYPE is f, SIZE may also be F for sizeof(float), D for sizeof(double) or L for sizeof(long double).
RADIX is d for decimal, o for octal, x for hexadecimal or n for none. BYTES is hexadecimal with 0x or 0X prefix, it is multiplied by 512
with b suffix, by 1024 with k and by 1048576 with m. Adding a z suffix to any type adds a display of printable characters to the end of
each line of output. --string without a number implies 3. --width without a number implies 32. By default, od uses -A o -t d2 -w 16.
