Обсуждение: postgres on the comman line
Hello, I like to automate a daily check and like to run select statement via cron but this seems to be more tricky than I thought.... I tried the following: su postgres -c "select count(*) from TABLE where xxxxxx;" I have the probelm that I am allways asked for the password - I did not find a way how to pass the password. Also I like to direct the result to a file, I assume I can do this via > but not haveing passed the first problem I did not check this. I am happy for every hint Thanks a lot Michael

It should contain lines with colon separated values consisting of host:port:database:user:password and must not be world-readable. | Also I like to direct the result to a file, I assume I can do this via > | but not haveing passed the first problem I did not check this. yes.

So you need something like: su postgres -c "psql -c 'select count(*) from TABLE where xxxxxx'" If you are the only one with an account on the machine then you might try to tweak ~postgres/data/pg_hba.conf and set method 'trust' for local access (no tcpip,psql without the -h option) . Also you could set env variables PGPASSWORD, PGUSER. > > I have the probelm that I am allways asked for the password - I did not > find a way how to pass the password. > > Also I like to direct the result to a file, I assume I can do this via > > but not haveing passed the first problem I did not check this. > > I am happy for every hint > > Thanks a lot > Michael > > > > > ---------------------------(end of broadcast)--------------------------- > TIP 4: Have you searched our list archives? > > http://archives.postgresql.org > -- -Achilleus
