Hi,
It is a newbie general question. I want to redirect the result of bdf in a
file.

I tried this.
[%] echo $SHELL
ksh
[%] bdf > toto ; bdf | tee toto ; bdf 2>toto

My Pb is that size of toto is always 0
Why ? How to redirect bdf output into toto file ?
Thanks

Did you see 100% anywhere in the bdf output?

Your last command is redirecting bdf's standard error output to toto.
Assuming bdf is running properly there will be no errors output to toto,
hence a zero length file:

% bdf > toto ; bdf | tee toto ; bdf 2> toto
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 311296 142968 167048 46% /
....etc
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 311296 142968 167048 46% /
....etc

% ll toto
-rw-rw-r-- 1 marsdenj usr 0 Nov 8 17:31 toto


Check each of your commands separately:

% bdf > toto
% ll toto
-rw-rw-r-- 1 marsdenj usr 2261 Nov 8 17:31 toto


% bdf | tee toto
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 311296 142968 167048 46% /
....etc
% ll toto
-rw-rw-r-- 1 marsdenj usr 2261 Nov 8 17:32 toto


% bdf 2> toto
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 311296 142968 167048 46% /
....etc

% ll toto
-rw-rw-r-- 1 marsdenj usr 0 Nov 8 17:32 toto

Is your command line really "bdf > toto ; bdf | tee toto ; bdf
2>toto"?

If so you are running 3 commands 1one after the other, each writing a
new version of toto.

bdf > toto writes the bdf output to toto

bdf|tee toto writes the bdf output to the screen and toto, replaceing
the previous bdf output

bdf 2>toto writes any error messages (usually none) from the bdf
command into toto, replaceing any previous contents

Try the commands 1 at a time.

Of course, I've executed commands seperatly and after each command I've run
ls -l
bdf => gives a correct standard output
bdf > toto => then ls -l toto prints 0
and so on for other commands (bdf | tee toto).

All your answers confirm that there is no syntax error with my command.
I'll try with >> and with tee -a
I'll check also if there is a quota limit with my account.

Many thanks for your answers.
