The first line of a file is as follows:
I need to remove the word example.4ge v.45353 from that line. I used the following command to truncate it
But here the version number 45352 may vary. So how can I make it as generic for any numbers?
Can anybody help me out?
Thanks in advance.

Reason: added code tags
what does this command do ? as in
does this command just make sure everything in the file is executed?
or does it flush the file?
Actually this is used on a file in a progress database but I believe it is a unix command? (2 Replies)
Hi People,
I need some Help to write a unix script that asks for a sentence to be typed out then with the sentence. Counts the number of spaces within the sentence and then echo's out "The Number Of Spaces In The Sentence is 4" as a example
Thanks

Hi,
I think my problem is a "simple" one to resolve. What i am looking for is a way in sed/awk to split a long line/paragraph into say 5 words per line.
For example:
Sentence/paragraph contains: 102 103 104 105 106 107 109 110 ....
I would like the output to be (if splitting every 5... (5 Replies)

I have a file that has the words I want to find in other files (but lets say I just want to find my words in a single file). Those words are IDs, so if my word is ZZZ4, outputs like aaZZZ4, ZZZ4bb, aaZZZ4bb, ZZ4, ZZZ, ZyZ4, ZZZ4.8 (or anything like that) WON'T BE USEFUL.

The title pretty much defines the problem. I have text files that are all in caps. I would like to convert them to lowercase, but have the first letter of the first word in each sentence in uppercase.

Hi there,
How I remove the first word of a sentence.
I have tried.
echo '1.1;' ; echo "$one" | grep '1.1 ' | awk '{print substr($0,index($0," ")+1)}'
For the below input.

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.
