I have a problem with the script below
#!/bin/sh
for vo in `find -maxdepth 1 -type f -regex "^\./*$"`
do
ls -l "$vo"
some other commands
done
It works fine until `find ...` returns files with spaces. I've tryed to change IFS but haven't succeed
Any solutions? (4 Replies)
I'm trying to do something like that:

I have files on my unix boxes that users have created with spaces.
Example: /tmp/project plan
ls -l "/tmp/project plan" works fine.

Hi All,
I see similar problems in past threads but so far no answers have worked for me. I am trying to write a script which parses a txt file that contains one filename per line, then finds those files on the local disk and copies them to a specified directory.

Hi
I hope someone will be able to resolve this little teaser!
I am running a script

I want to ftp all the sh files in the directory. Also if any of the file name
contains spaces in them, it should be converted to underscores before it is ftped. I wrote the following code below:

I have a problem mounting images because of the spaces in the filenames. Does anyone know how to rename files by removing the spaces with the find command?

Hi,
I have files like below, In files coming as spaces. Before transfering those files into ftp server. I want to remove the spaces and then can transfer the files into unix server.
e.g: filenames are
1) SHmail _profile001_20120908.txt
2) SHmail_profile001 _20120908.txt
3) sh... (3 Replies)
I'm trying to handle some files with spaces in their name using "" or \ . Like "file 1" or file\ 1.
My current confusion can be expressed by the following shell script:

echo -n "ls: " ; ls
echo ---

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.
