hi all,
suppose a string:
abc/def/ghi/jkl/mn.txt
and i want to get the file name without the path.
however, different files have different paths, therefore the number of delimiter is uncertain.
thanks so much! (3 Replies)

I have the following script working fine, and need to generate a file delimiter (with tab or special character) for Excel data import.

Hi;
I want to write a shell script that will split a string with no delimiter.
Basically the script will read a line from a file.
For example the line it read from the file contains:
99234523
These values are never the same but the length will always be 8.
How do i split this... (8 Replies)

Hi ,
I need to get the delimiter "-" count in a particular string.
string= SYS_NAME-123-S5-2008-10-20.LOG
the delimit "-" count is 5 .
Using sed or awk can I know the count ?
I have seen how to get the count for delimiter in a file but not a string :(
Thanks,

Hi,
I'm wondering what is the best way to parse out a long string that has a specific deliminator and outputting each token between the delim on a newline?
i.e. input
text1,text2,text3,tex4
i.e. output
text1
text2
text3
text4 (8 Replies)

Hi,
I need to split a string, either using awk or cut or basic unix commands (no programming) , with a multibyte charectar as a delimeter.
Ex:
abcd-efgh-ijkl
split by -efgh- to get two segments abcd & ijkl
Is it possible?
Thanks

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%)
