I'm using the UNIX csh and i wish to use recursion to nav my way up (or down as it is) a given folder.
My little test script is called "r" and takes a folder as argv (or $1)
#!/bin/tcsh -f
set allFiles = `ls -A $argv`
cd $argv
while ($#allFiles)
if (-d... (1 Reply)
I am running a korn shell script which has a recursive function.
The script ran for 117 iterations and ended up with the following error
"recursion too deep".
what should be done to avert this?
Thanks in advance

Hello everyone. I'm not sure if I should allow recursion on our external DNS server. I just finished configuring the server and this is the last parameter I'm pondering over. We are an internet company and we rely on customers going to our website and our website is referred to on our external... (1 Reply)
Hello every body. I am trying to find the factorial using the following code. But it is giving the syntax error. I tried very much but in vain. Thanks in advance for helping me

I want to halt a tail recursive function after certain validation. I want to come out of entire recursion without unwinding phase. How can i achieve that . The coding is done in C language. (5 Replies)
Hi,
Question: how come the output is like that? Can explain to me abit. I am learning C.
Thanks!
#include <stdio.h>
#include <string.h>
void printit(char line_of_char, int index);
int main()
{
char line_of_char;
int index = -1;
strcpy(line_of_char, "This is a string.");

Can someone please explain me why the following script calls it self recursively:
#!/bin/bash
echo Called
$0
while this not:
#!/bin/bash
echo Called
$($0)

bup-margin
bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
