Dear Elixir,
I tried in the same way.But it didn't work.Another thing that I suspect is original strings that I posted were like below :-
But actual strings that are coming are like below:-
I suspect about special character "_"(underscore) that comes in string.
Do we need to make any change in sed command to handle this ?
Hi Everyone!
I am trying to extract records between date makers in a log file. My selection string doesn't work, though. Please help.
This test works, if I manually enter the two date-strings (output=28 lines):
# sed -n '/\/,/\/p' ./access_log
But if the date string is a variable, it will... (2 Replies)
I have read many threads, but I still didn't find the right answer. May be i didn't find the right thread, though are so many threads for the same question.

I am trying to use the below sed command to replace all "|" to ^, in a folder had 50 dat files. when i tried with 1 file it worked but when i tried with wild card, is not working.

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.
