Copy files listed in a text file - whitespace problem.
Hi,

Say I have this text file <copy.out> that contains a list of files/directories to be copied out to a different location.

Code:
$ more copy.out
dir1/file1
dir1/file2
dir1/file3
"dir1/white space"
dir1/file4

If I do the following:

Code:
$copy=`more copy.out`

$echo $copy
dir1/file1 dir1/file2 dir1/file3 "dir1/white space" dir1/file4

$cp -v $copy ./temp
dir1/file4 -> ./temp/file4
cp: space": No such file or directory
cp: "dir1/white: No such file or directory
dir1/file3 -> ./temp/file3
dir1/file2 -> ./temp/file2
dir1/file1 -> ./temp/file1

All of the files managed to be copied except for the file with a whitespace.

I have tried using for loop, but the same thing happened.

Code:
$ copy=`while read line; do echo "$line"; done < copy.out`

$ echo $copy
dir1/file1 dir1/file2 dir1/file3 "dir1/white space" dir1/file4

$ cp -v $copy ./temp
dir1/file4 -> ./temp/file4
cp: space": No such file or directory
cp: "dir1/white: No such file or directory
dir1/file3 -> ./temp/file3
dir1/file2 -> ./temp/file2
dir1/file1 -> ./temp/file1


I edited copy.out and replace "dir1/white space" with dir1/white\ space but it didn't work. Just by simply removing the double quotes failed to work either. I understand that by using echo, it will flatten any whitespace in $variable into a single space, so I've tried using double quotes $variable, but again, it failed to copy the file with a whitespace.

I don't like whitespace in files/dirs name, but some people seem to like it, so I'd like to know how to fix this problem.

Any advice offered is appreciated.

Thanks.

bundle

BUNDLE(1)						      General Commands Manual							 BUNDLE(1)

NAME

       bundle - collect files for distribution

SYNOPSIS

       bundle file ...

DESCRIPTION

       Bundle  writes  on  its	standard output a shell script for rc(1) or a Bourne shell which, when executed, will recreate the original files.
       Its main use is for distributing small numbers of text files by mail(1).

       Although less refined than standard archives from ar(1) or tar(1), a bundle file is self-documenting and complete;  little  preparation	is
       required on the receiving machine.

EXAMPLES

       bundle mkfile *.[ch] | mail kremvax!boris
	      Send  a  makefile  to Boris together with related and files.  Upon receiving the mail, Boris may save the file sans postmark, say in
	      gift/horse, then do

       cd gift; rc horse; mk

SOURCE

       /rc/bin/bundle

SEE ALSO

       ar(1), tar(1), mail(1)

BUGS

       Bundle will not create directories and is unsatisfactory for non-text files.
       Beware of gift horses.
