Hello, I am new to this forums. I need help with shell, and ksh in particular. I have a case statement that does something if -k. So it looks like:

-k) PUT=y, SEND=1
Thats all good and dandy. But now I want to change it where whether or not the user puts -k or not, it will do... (2 Replies)
Hi All,
The means I use to ignore case, as an example is the following snippet:
It should accept any oof the following y|Y|YES|Yes|n|N|NO|No
echo "Enter Y/N to continue: "

Folks - I found this code on the forums to extract a paragraph for a matching pattern but I don't know how to make it ignore case.
grep "-ip" is not an option for me as I am on SUSE LINUX.
Thanks for ur help.

If I'm using a program that is expecting certain filenames and directories to be all CAPS, isn't there a way to ignore this in linux/cshell scripting? I.e., similiar to ignoring spaces with " (i.e., directory is directory 1, can ignore by typing "directory 1".) ?? (2 Replies)
Hi,
I have a Python unit test cases source code file which contains more than a hundred test case methods. In that, some of the test case methods already have prefix 'test' where as some of them do not have. Now, I need to add the string 'test' (case-sensitive) as a prefix to those of the... (5 Replies)
I have a bi-lingual database of a large number of dictionaries. It so happens that in some a given string is in upper case and in others it is in lower case. An example will illustrate the issue.

toll tax=टोल
I want to treat all three instances of toll tax... (3 Replies)

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.
