Hi all,
Have the following code(1) producing the results(2 & 3).
Would like to know if there is a way to format the two reports created in a similar fashion.
IE - The first is formatted nicely as a result of the echo "$xmpbdate $xavgs" >> $xmpbrpt
However when I attempt to do the same on... (7 Replies)
Hi need some advice..

Now I need to format the above output as below.

Hi
I tried running the below
awk 'BEGIN { printf ("%s %-51s %s %-7s %s",$var1,$var2,$var3,$var4,$var5)}'
from the command prompt and it is not working.
Getting the error
awk: Field $() is not correct.

Actually my requirement is to form a string based on... (6 Replies)

Sorry for being a n00b, but I'm having a lot more trouble than I should with formatting the output to the program I finally completed. I'm basically looking for the linux equivalent to setw( ) from c++ so that I can print things in columns like this (but without the underlines lol):

I am using FORTRAN 90 on AIX 5.3 and need to output my data to a tab-delimited file. It must have actual tabs, and I cannot figure out a way to make it work. The resulting file will be imported into another application (quickbooks) as an .iif file....for some reason, it needs the tabs; spaces do... (2 Replies)
Hi,
I am trying to use printf command and format certain output in a specific format as under:

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.
915 of 1612581 (0.057%)
