Hello everyone,
I want get numbered lines from a file. and i can do it with: sed = file.txt | sed "/./N; s/\n/ /" | sed -n "5,7p"
but the output that i get is something similar to:
5 line5
6 line6
7 line7
and i want something like this (with 2points after the number):

Is there a way to number lines and use something other than ":" to separate the number from the line?
Or can anyone recommend a way to replace the ":" with a tab?
Here's what I'm working with:

16860:46
16861:39.63
16862:33.88

Running into a little problem with blank lines.
My file is of this format:
To number each line of the file i would use:
n=1
echo "$FILE" |
while read line
do
echo "$n) $line"
n=`expr $n + 1`
But really, i dont want to number the blank lines.
What i've tried is to use sed... (13 Replies)
hello again guys,
I tried to make a script but due to array's limitations I didn't succeed...so I'm asking you :)
I need numbering the lines according to date (everyday I need to restart the counter)
for example:
ABCBD 20080101 XXX 1
FSDFD 20080101 BBB 2
FSDFD 20080102 HHH 1
and so... (3 Replies)

I am using ghostscript to convert a multi-page pdf file to individual jpg files. I am wondering if there is a way to get ghostscript to start numbering the output jpg files from zero? What i am trying to convey is that it starts naming my files from page_001.jpg, page_002.jpg, etc., and would like... (0 Replies)
Hi,

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.
915 of 1612581 (0.057%)
