Hello All,
This question is actually for the service console of VMware ESX 3.5 but is relevant to this forum I think. I have been advised to use the following commands:
for i in `find /vmfs/volumes/Test_VMFS/ -name "*.vmx"`
do
echo "$i"
#sed -i 's/scsi1:0.present =... (3 Replies)
HI
In my script, i am reading the input from the user and want to find the length of the string.
The input may contain leading spaces. Right now, when leading spaces are there, they are not counted.
Kindly help me

Hi
I have an XML file with strings XABCD, XEFGHX and XIJKLX. I would like to replace XABCDX with "This is the first string", XEFGHX with "This is the second string" and XIJKLX with "This is the third string".
What is the best way to implement this? Should I have a file with the data that is... (4 Replies)

Hi there,
I don't understand the following behavior:

Is this possible?
I have a for loop in a shell script reading a list, but I want each line to be a loop, not each thing with a space.
Here is the example:
HOSTLIST="\
1.2.3.4 serverA
1.2.3.5 serverB"
for NBUHOST in `echo $HOSTLIST`
do
ssh ${SERVERNAME} "echo "${NBUHOST}"... (3 Replies)
Hi Guys,
I'm trying to find all files with a particular extension and then loop some actions. The problem is that if the files have spaces in their names I get end up being each word as a separate result rather than the entire file.
ext=".txt"
out=".rtf"
for i in $( find "$1" -name "*$ext" );... (9 Replies)
Hi all,
I've been tangoing with this one for a couple of days now and I'm still not making any progress.
Basically I'm trying to match three numbers in a string from a text file with matching numbers in a jpeg, and then copying the results to another folder.
Data looks like this:

Hi
I'm trying to loop through an array that contains other arrays and these arrays consist of strings with spaces. The problem is that I can't seem to preserve the spacing in the string. The string with spaces are either divided into multiple items if I change IFS to \n or all the elements of... (4 Replies)
I have a folder with files and I have to process them in a loop. However the filenames have space characters, so the list get split.
$ touch "File Number_1"
$ touch "File Number_2"
$ ls "/tmp/File Number"_*
/tmp/File Number_1 /tmp/File Number_2
I tried following (sorry for using the... (3 Replies)

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.
