how to list all databases?

We used to write an esql/c program to do an update statistics medium every night.But we have to support a lot of different platforms now and so I wrote a ksh-script, that does the same job. I use oncheck -pc to get a list of all all databases and use this list to do an update statistics with dbaccess. But oncheck is very slow! Who knows a faster method, I don't know much about the system tables, but maybe there is a better method using dbschema etc.. Should be something like <command> |grep [-v ] xxx | awk '{print $i}' or dbaccess <<EOF SQL-COMMANDS EOF Thankx, Erik
