[Bug-tar] tar and gzip

[christophe . kirch]

Hi Group,
I hope you will be able to help me here...

I am an SQR Report Developer.
My report produces several csv files, which i need to tar, then compress,
and then send by email.
To do so from the SQR, i am calling a unix command.

Here is the syntax i am using :
cd (my directory) ; tar -cvf file.tar *.csv | gzip --best > file.tar.gz;
uuencode file.tar.gz file.tar.gz | mailx -s Subject
address@hidden

=> the TAR command works great
=> The mailx command works great also
BUT the GZIP command does not work at all... the gz file created is
empty... so i guess my syntax is wrong.

I have been trying many many different syntaxes.
Sometimes with the pipe, sometimes with the semi-column, etc..

I have also tried the tar option -z (which invokes gzip) : the gz file was
created, it contained my data, but nothing was compressed !!

Thank you for helping, since i am about to forget about using gzip...
(fyi, i currently use "compress" which works fine, but does not compress as
much as gzip...)

Thanks for your help!
