I am getting the coutput like this as show below in one single line, where as the command is executed is several lines and the output should also be requied in several lines, not in one single line.
Anyone any idea?

Hi all,
For a intro UNIX course I'm taking, I need to use the command "tr" to display a file on standard output without any newlines (all on one line).
I assume I would start with "cat filename | tr" but don't know what to put after tr.
Any ideas would be lovely!
Thanks. (3 Replies)
I've got a log file from automatic diagnostic runs. The log file is appended to each time an automatic log is run.
I'd like to just pull certain lines from each run in the log file, and concatenate them into 1 comma delimited line (for export into excel or an html table).
Each diagnostic run... (3 Replies)
Hi all,
I was wondering if someone could tell me a way to extract from a file lines where you search for a phrase and then also extract the next X lines after it (i.e. take a block of text from the file)?
Example
{
id=123
time=10:00:00
date=12/12/09
{

Hello UNIX experts,
I have 124 text files in a directory. I want to extract the 45678th line of all the files sequentialy by file names. The extracted lines should be printed in the output file on seperate lines.
e.g. The input Files are one.txt, two.txt, three.txt, four.txt
The cat of four... (1 Reply)

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.
