Filenames with blanks

Command like this:
    rsync  -rxlupogtSvve ssh
$src_host:"/home/wss_disk/calendar.data/'Conference Calls'"
$targ_dir
works fine with blanks embeded in the file name.
When I try to script it like this:
    COM='`find '$src_dir'  -mtime -'$days' -type f `'
    rsync  -rxlupogtSvve ssh  $src_host:"$COM" $targ_dir
works fine on regular filenames, but does not see the ones with blanks
in the middle.

I changed my COM to pipe through little script to produce the same
output where either the whole filepath or just the file name will be
quoted (as in the first example). That breakes it complitely and this
version does not work even for single word files. Output looks like
this:
.......................
receiving file list ...
link_stat /home/wss_disk/calendar.data/'Conference : No such file or
directory
link_stat Calls' : No such file or directory
link_stat /home/wss_disk/calendar.data/'Economic' : No such file or
directory

I probably am missing something simple, but could not figure what is it.
Please advise. Thank you.

Filenames with blanks

The output of the file list is treated as a list.  The easiest solution 
would be to iterate through the list.
Now, you understand that as you have constructed this, you create a 
commandline in a variable.  In the "$COM" you are executing that 
commandline, and putting its contents as a part of the $src_host: token. 
The find is NOT being executed on the remote, so what you are doing is 
asking the remote for its copy of each file you have a file in $src_dir 
that is less than $days old.  Is that actually what you want?

A better solution to the spaces problem is
++++++++++++++++++++++++++++++++++++++++++++++++++++++
find $srcdir -print |
grep ' ' |
while read item
  do
    mv $item `echo $item |tr ' ' _`
  done
++++++++++++++++++++++++++++++++++++++++++++++++++++++

Yeah, I know you CAN have spaces in filenames, but it's such a pain in the 
ass, just to satisfy some luser who wants to use them.

As Tim pointed out scanning $dest_host for files that
were recently modified to overwrite them if they were
changed on the $src_host makes very little sense.

rsync handles file names with spaces just fine if you let
it.  Why do you think you need to create this file list in
the first place when you are using the -r option?

Based on your design decisions i doubt that you quite
understood  understood what Tim meant by a list so i'll
illustrate.  Your find operation means that $COM is set to
something like
	/home/wss_disk/calendar.data/Conference foo
	/home/wss_disk/calendar.data/Economic bar

The result being this command line
	rsync  -rxlupogtSvve ssh
$src_host:"/home/wss_disk/calendar.data/Conference foo
/home/wss_disk/calendar.data/Economic bar" $targ_dir

Putting quote marks inside $COM won't protect the spaces.
The quotes have to be outside of $COM.

If you can explain why you need the find instead of doing
	rsync  -rxlupogtSvv -e ssh $src_host:$src_dir/ $targ_dir
I'll be glad to show you how.

Not so. If you look carefully at Ivan's quoting, you'll note that
he put the backticks inside single quotes, which saves them for the
$src_host. For instance:

COM='`ls -1d f*`'
rsync -av $src_host:"$COM" /tmp

That command would work just like this simpler command:

rsync -av $src_host:f\* /tmp

Ivan Kovalev wrote:> COM='`find '$src_dir' -mtime -'$days' -type f `'

The quoting problem is a shell problem due to the backticks. Backticks
split the string at spaces, regardless of the quoting or backslashing
that you may attempt to use in the output (which is ignored because the
shell isn't doing parsing there, just word-splitting). To fix this,
you'll have to affect how the backticks split the output. I can't
figure out a way to get rsync to set IFS in the right spot to affect
just the backtick expansion, so perhaps the only solution is to use a
different command-running syntax.

If your login shell is zsh, you could use this command:

COM='${(f)"$(find '$src_dir' -mtime -'$days' -type
f)"'

This quotes the find command's output (so that it doesn't get split),
and then explicitly splits the output based on newlines. I don't know
if bash has something similar (since I don't use bash).
