I have a property file which contains a string
It has be to replaced with another string, and value of that string should be initialized at runtime. So I use placeholder there. My substituted string should look like
where
So after substitution it should look like
I am using sed command
But only placeholder is coming there, not the values are populated. After running the SED it apprears
it seems sed is not getting the values
Any ideas where I am going wrong? I am happy to use any other substitution commands as well
I am writing a script that looks for files. I need to know if there is a placeholder character when doing this. I know that you can user a wildcard (*) character, but I would prefer to be a bit more specific. When I get files in a specific directory, I know part of the name, but not the rest and... (7 Replies)
Hi
I have the following file that i need to run a sed command on

I want to be able to replace a line i.e the second one with '2<tab>failed'. As the first number is unique that can be used to search for the relevant line (using ^2 i... (5 Replies)

Hi
Can anyone provide me the replacement of sed with xargs perl syntax for the below

This should be without looping has to take minimal time for search (0 Replies)
Hi all,
Thanks in advanced.
This question really bothered me much. What i want is to replace any times of repeated 'TB' to 'T', below is example.
It can be fullfil by AWK and perl, but my desire is using SED to realize it.
So here means we treat TB as a whole part, which means 's/TB*/T/'... (4 Replies)
This seems like it should be an easy problem, but I'm a noob and I can't figure it out. I'm trying to use sed, but would be happy to use anything that does the job.

Hi,
i have a file with lines,

Hello,
I'm using Bash and Sed to replace text within a text file (1.txt) twice in one script. Using a for loop I'm initially replacing any 'apple' words with the variable 'word1' ("leg). I'm then using another for loop to replace any 'apple' words with the variable 'word2' ("arm"). This task is... (2 Replies)

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.
