mysqldump problems too

[jaco]

I'm having problems with mysqldump too.

I'm trying it on a Suse Linux 6.2 system, from the /usr/bin directory as root, typing 
./mysqldump --all-databases > backup.sql

as is explained on  http://www.mysql.com/doc/m/y/mysqldump.html

The response is :   ./mysqldump: unrecognized option `--all-databases'


I tried almost all different permutations of the --all-databases option, what am I 
doing wrong?


Thanks in advance

Jaco
