Обсуждение: Using psql on command line

I would like to run a cron job nightly to vaccuum a few databases, but how
do you execute from just a command line?  I tried like:

psql mydb < vacuum
psql mydb | vacuum

etc.

Thanks.

Brian

One of

   ~$ echo "vacuum" | psql mydb
   ~$ psql mydb -c "vacuum"

Note that you'll have to be careful about the environment of the user
which is running the cron jobs (PGDATA etc).

It's elephants all the way down

you should look at the manual for psql.. thats what I just did.. looks
like it would be something like this..

psql -c vacuum <tablename> -d dbName

if you can't find the man file... try the postgres home page.
(www.postgresql.org) or look in pgsql/man/man1/ on your local system...
