Description:

#       Just that the following commands (when pasted to command-line) can be 
easier read...
                clear
#
#       Imagine the folder '/tmp/bla' whith the follwowing contest:
#               2 files named: "a aaaaa aaa.mp3" and "c - c.mp3"
#       (
                mkdir /tmp/bla;     touch "/tmp/bla/a aaaaa aaa.mp3";       
touch "/tmp/bla/c - c.mp3"
#       )
#
#       Now try to process all these files in a bash-script with the following 
commands:
#
                for a in `find /tmp/bla -iname "*.mp3" -printf "\"%f\" "`; do   
        echo "'$a'";            done
#               
#       It gives you:
#               '"a'
#               'aaaaa'
#               'aaa.mp3"'
#               '"c'
#               '-'
#               'c.mp3"'
#               
#       But I think it SHOULD BE:
#               'a aaaaa aaa.mp3'
#               'c - c.mp3'
#               
#       Because:
                tmp=`find /tmp/bla -iname "*.mp3" -printf "\"%p\""`;            
echo "tmp='$tmp'"
#       gives you:
#               tmp='"a aaaaa aaa.mp3" "c - c.mp3"'
#       And:
                for a in "a aaaaa aaa.mp3" "c - c.mp3"; do          echo 
"'$a'";            done
#       gives you:
#               'a aaaaa aaa.mp3'
#               'c - c.mp3'
#
#   And to clear it up at finish:
        rm -R /tmp/bla

#
#       Is this a bug or a feature?
#
#       Or (if it's NOT a bug): How is it possible to get the "SHOULD 
BE"-result ??? 
#       (Help would be VERY APRECIATED! - although I KNOW, that this is NOT the 
bash-help-line! 
#       - because I really think this is/should-be a bug...)
#
#
#       If it is NOT a bug, then please give me at least a short remark on that!
#   ( email: address@hidden )
#       This would be nice.
#
#   Thanks right now!
