The syntax of the script suggests the Bourne-shell. If this is the case one
can tell the Shell to ignore the space in the name, i.e. do not treat it as
name separator.

The IFS parameter tells the Bourne-shell which characters use to separate names
(IFS means: internal field separators), so before the "for j in $trashlist"
line, one can insert the declaration :
IFS="
"
(i.e. IFS string, equal sign, double quote, return, and double quote again)
This will tell the Shell to take all names from the trashlist up to the
new line sign.

The manual for sh(1) informs, that IFS is ignored for root, and when the
effective user is different from the real one. I have checked for root and
it still works.
Manual bug ?  :-)

After playing with this for a while, I got the following to work
(Although I used a slightly different command)

Instead of referencing your file to trash as $j,
try referencing it as "${j}". (Include quotes)

This works for direct commands like 
/bin/rm "${j}"

You will have to test it for find.

Regards,

John

I have written a script that 'cleans' hard disks but is more elaborate  
then the one you posted.  Yes, it does handle spaces in the file names but  
doesn't handle some of the special characters such as '?'.  I'm satisfied  
with 95% for now but will eventually rewrite it in perl.

This script not only processes .NextTrash but cleans things like  
uucppublic, uucp, /tmp, and backup files.

The script is copyrighted but I can send it to you as a beta test site.   
Feedback will be required.  The 'clean' script is but one of a suite of  
sysadmin scripts I have written.  Some of the others include:  one that  
cruses through all of the NetInfo domains listing the domains and/or hosts  
under those domains -- useful for multi level domain structures (here at  
Trirex we have a four level);  another gathers all of the passwd entries  
from all of the domains and hosts and submits them to Crack.

We're considering marketing those scripts.  They cost money to develop.   
On the other hand, we might dump them into the public domain for education  
institution use only.  Decisions, decisions...
