Actually,I think "AB" and "BA" should be treat as two different conditions.If so,my code shows how to do this(produce 2 words from 3 words).While if not,before doing the count(),you can sort the oss.str() to make sure there is only "AB" or "BA" in the set.
Is anyone know some scripts to generate random number without repetition using bash; for example generate 10 different random numbers.

Hi all,
I have a scenario, like consider a file abc.txt,
inside abc.txt, the contents is
value1 = aaa,
value2 = bbb,
value3 = ccc,
value1 = ddd.
In this situation i need to throw an error for the repeatation of keys like "value1" is repeating twice.
how to handle this using bourne... (1 Reply)
Hi,
Thanks for keeping such a help-full platform active and live always.
I am new to this forum and to unix also.
Want to know how to count the repetition of a field in a file. Anything of awk, sed, perl, shell script, solution are welcomed.

Hello,
This is my first post so, Hello World! Anyways, I'm learning how to use unix and its quickly become apparent that a strong foundation in regular expressions will make things easier. I'm not sure if my syntax is messing things up or my logic is messing things up.

Suppose I have a word which is repeating in a string continuously. I have a set of intervals. Then how do I find the number occurrences of that word in those intervals and their location of occurrences. For example - Suppose there is a huge string anfie.......sirn of 10000 letters.

So, I have this command:
mkdir rolled
for %%x in (*gif) do convert %%x -roll +2+6 %%x|move %%x rolled
I'd like to have the +2 and +6 accumulate here.
In each new gif tackled, it should increase by the amount: +2 (for x) and +6 (for y)
Is this possible?

mincore
MINCORE(2) Linux Programmer's Manual MINCORE(2)NAME
mincore - get information on whether pages are in core
SYNOPSIS
#include <unistd.h>
#include <sys/mman.h>
int mincore(void *start, size_t length, unsigned char *vec);
DESCRIPTION
The mincore function requests a vector describing which pages of a file are in core and can be read without disk access. The kernel will
supply data for length bytes following the start address. On return, the kernel will have filled vec with bytes, of which the least signif-
icant bit indicates if a page is core resident.
For mincore to return successfully, start must lie on a page boundary. It is the caller's responsibility to round up to the nearest page.
The length parameter need not be a multiple of the page size. The vector vec must be large enough to contain length/PAGE_SIZE bytes. One
may obtain the page size from getpagesize(2).
RETURN VALUE
On success, mincore returns zero. On error, -1 is returned, and errno is set appropriately.
ERRORS
EAGAIN kernel is temporarily out of resources
EINVAL start is not a multiple of the page size, or len has a non-positive value
EFAULT vec points to an invalid address
ENOMEM address to address + length contained unmapped memory, or memory not part of a file.
BUGS
mincore should return a bit vector and not a byte vector. As of Linux 2.4.5, it is not possible to gain information on the core residency
of pages which are not backed by a file. In other words, calling mincore on an region returned by an anonymous mmap(2) does not work and
sets errno to ENOMEM. Unless pages are locked in memory, the contents of vec may be stale by the time they reach userspace.
CONFORMING TO
mincore does not appear to be part of POSIX or the Single Unix Specification.
HISTORY
The mincore() function first appeared in 4.4BSD.
AVAILABILITY
Since Linux 2.3.99pre1 and glibc 2.2.
