Hi,
I am having trouble converting a text file. I have been working for this whole day now, still i couldn't make it.
Here is how the text file looks:

I am new to unix and awk/sed etc... using C-Shell.
Basically, I have a fixed length file that has 4 different record types on it, H, D, V, W all in column 1. I need to change all the W's in column 1 to D's. in the entire file. The W's can be anywhere in the file and must remain in the same... (3 Replies)
Hello,
A basic query. How can I remove a string from a specific column.
For example, remove "abcd" just from column 2 in example file:
abcd abcd1
abcd abcd2
abcd abcd3
to get output:
abcd 1
abcd 2
abcd 3
Thank you!:) (4 Replies)

Hi,
I have two input files as
File1 :
ABC:client1:project1
XYZ:client2-aa:project2
DEF:client4:proj
File2 :
client1:W-170:xx
client2-aa:WT-04:yy
client4:L-005A:zz
Also, array of valid values can be hardcoded like
Output :
ABC:W:project1

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.
