ok, it's flush doing the job in my case, many thanks ;-)

also what is the best practice, writing :
xml=""
album_list.each do |k,l|
   xml=xml+"<name first=\"#{l[0]}\" last=\"#{l[1]}\" company=\"#{l[2]}\"
organization=\"#{l[3]}\"/>\n"
end
tmpFile.puts xml
tmpFile.flush
<code>

or that :
<code>
album_list.each do |k,l|
   tmpFile.puts "<name first=\"#{l[0]}\" last=\"#{l[1]}\"
company=\"#{l[2]}\" organization=\"#{l[3]}\"/>\n"
end
tmpFile.flush

that's to say writing to the file the whole result at once or each line
after each line ?

and also, if, after :
<code>
system("iconv -c -s -f MACROMAN -t UTF-8 #{tmpName} >
#{xmlDir}/#{xmlName}")
<code>

i suppress the temporary file like that :
<code>
system("rm -f  #{tmpName}")
<code>

i get a warning :
-----------------
../AddressBook2vCardXml.rb:56: warning: Insecure world writable dir
/Users/yvon/work/Ruby/rubyaeosa-0.2.3/sample/, mode 040777
-----------------
for this latest line
the perms in the working folder being :
-rw-rw-rw-    1 yvon  yvon   12387 Dec 27 08:56 AddressBook.xml
for files
and :
-rwxrwxrwx    1 yvon  yvon    1687 Dec 27 08:56 AddressBook2vCardXml.rb
for ruby scripts.

if i change the perms to :
-----------------
-rwxr--r--    1 yvon  yvon   12387 Dec 27 08:56 AddressBook.xml
-rwxr--r--    1 yvon  yvon    1687 Dec 27 08:56 AddressBook2vCardXml.rb
-----------------
that's to say only user:user as right to write|exec a file in that
folder, i get the same warning with the same "mode 040777" ???


also in the /tmp directory the file perms is only :
-----------------
-rw-r--r--    1 yvon      wheel  12340 Dec 27 09:07
AddressBook-MACROMAN.xml
-----------------

seems to be correct for me ))
i thought it was special methods in ruby, in order to get tmp file name
???
