Dear all,
How can i unset arrays. I mean all the subscripts including the array after using them.
Could you direct me to some links of array memory handling in the korn shell.
Thanks (2 Replies)
PHP question...
I have an SQL query that's pulled back user IDs as a set of columns. Rather than IDs, I want to use their names.
So I have an array of columns $col with values 1,7,3,12 etc and I've got an array $person with values "Fred", "Bert", "Tom" etc
So what I want to do is display the... (3 Replies)

I've noticed something interesting in C++ programming. I've always done tricky stuff with pointers and references to have functions deal with arrays. Doing exercises again out of a C++ book has shown me an easier way, I didn't even know was there. It's weird to me.
When dealing with arrays, it... (4 Replies)

OD(1) User Commands OD(1)NAME
od - dump files in octal and other formats
SYNOPSIS
od [OPTION]... [FILE]...
od [-abcdfilosx]... [FILE] [[+]OFFSET[.][b]]
od --traditional [OPTION]... [FILE] [[+]OFFSET[.][b] [+][LABEL][.][b]]
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, ignoring high-order bit
-b same as -t o1, select octal bytes
-c same as -t c, select ASCII characters or backslash escapes
-d same as -t u2, select unsigned decimal 2-byte units
-f same as -t fF, select floats
-i same as -t dI, select decimal ints
-l same as -t dL, select decimal longs
-o same as -t o2, select octal 2-byte units
-s same as -t d2, select decimal 2-byte units
-x same as -t x2, select hexadecimal 2-byte units
If first and second call formats both apply, the second format is assumed if the last operand begins with + or (if there are 2 operands) a
digit. An OFFSET operand 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, ignoring high-order bit
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, and may have a multiplier
suffix: b 512, kB 1000, K 1024, MB 1000*1000, M 1024*1024, GB 1000*1000*1000, G 1024*1024*1024, and so on for T, P, E, Z, Y. Adding a z
suffix to any type displays printable characters at the end of each output line. Option --string without a number implies 3; option
--width without a number implies 32. By default, od uses -A o -t oS -w16.
