Merge multiple lines to one line when line starts with and ends with
example:
in this example I need to be able to grab the comment as first word and ; as the last word and it might span a few lines. I need it to be put all in one line without line breaks so I can grep for comment and pull the whole line out.
comment Now_TB.table column errac is for error messages 1 - first 2 - second 3 -third ;
also there will be a lot of these in the file and other items between these... but from comment to ; all of that goes in one line.
thank you

I'm sure this will be an easy question for you experts out there, but I have been searching the forum and working on this for a couple hours now and can't get it right.

Hi,
Can anyone help me for merge the following multi-line logs( the black lines) which beginning with time: into one line. For the line with "-", it needs to be deleted. Please see the red color line.

Dear all,
I am new to this community. I need a script that will merge two lines of a text file based on some character. for example-

Hi Experts,
This is my input file.
input.txt

1. If this file has single line, then leave it, print the single line
else
merge the 4 lines above into 1 line as below

I am trying to combine lines with these conditions:

Hi all, I'm relatively new to scripting, I can do pretty basic things. I have a daily log file that looks like:

event status=0;
userid=user1;
authid=user1;
application id=10.10.10.10.11111.12345678901;

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%)
