Hi
When im listing (ls -al ) its listing directories without / at the end of directories
dir1 dir2 dir3
and i need to list directories with
dir1/ dir2/ dir3/ and this should not be made by command ls -F
/ should be embedded at the last
since one of the scripts reads directories... (1 Reply)
The called program gets as parameters two or more integers and
and returns 0 if all pairs of two are relatively primes, and 1
otherwise. The callee shall read a sequence of numbers and tell
whether they two by tworelatively primes. (1 Reply)
Hi All,

The above is my script, which writes the large file into a file called bigfile.txt. My script contains only the above two lines.
after execution i am getting the output like

1) when user login to the server the session got colosed. How will resolve?
2) While firing the command ls -l we are not able to see the any files in the director. but over all view the file system using the command df -g it is showing 91% used. what will be the problem?
Thanks in advance. (1 Reply)
Hi All ,
I am having a set of file, when i list like ls -l *filename* it is listing all file. If is do ls -l filename.ext it is not listing the file. I dodnt know what will be the cause
Example:

Hello,
In my directory i have got a list of files like below

I have done ls -lrt unix1.csv, how can i get my unix1y.csv also get listed along with this.. (5 Replies)
Hello,
I can't figure out how to solve this problem. I know that is not something very difficult, but it doesn't work for me. Any help is important for me, thank you!

Each such process will establish if the assigned... (1 Reply)

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.
