My requirement is to seperate the email id's into 2 groups.. emailid1@blh.comemaild2@blh.comemailid3@blh.com should come in one group and asdf@blah.com should come in another group, so that i can call email functionality twice. Currently, i am using below code to achive this:
So, no matter what may appear in any file somewhere, what you want is:
or with your changes since then:
We all mistakenly assumed that you were trying to read a list of email addresses from a file and split them into groups based on some criteria derived from the addresses themselves. And since you had three addresses ending with "@blh.com" and one address ending with "@blah.com", we all assumed that that was the criteria to be used to determine which group should contain an address.
It could have been that you wanted addresses starting with "a" in one list and addresses starting with "e" in the other list. It could have been that you wanted addresses with a digit before the "@" in one list and addresses with an alphabetic before the "@" in the other list. It could have been that you wanted the 3rd address in one list and the other addresses in the other list. It could have been some other pattern none of us saw.
But, since you just want two lists containing exactly those names, why did you give us the red herring talking about a file containing your list of names??? The file is irrelevant.
I have a variable with data in this format
field1;field2;field3
I wanted to split the variable like this
field1
field2
field3
this statement was working fine echo $key_val | awk '{gsub(";" , "\n"))'
but sometimes we get the data in the variable in this format... (3 Replies)

Hello;
I have a file consists of 4 columns separated by tab. The problem is the third fields. Some of the them are very long but can be split by the vertical bar "|". Also some of them do not contain the string "UniProt", but I could ignore it at this moment, and sort the file afterwards. Here is... (5 Replies)

In the tab-delimited input below I am trying to use awk to -10 from $2 and +10 to $3. Something like
awk -F'\t' -v OFS='\t' -v s=10 '{split($4,a,":"); print $1,$2-s,$3+s,a,$5,$6} | awk {split(a,b,"-"); print $1,$2-s,$3+s,b-s,b+s,$5,$6}' input
should do that. I also need to -10 from $4... (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.
