Sure, you can use psql for that, here a simple example:
,----[ my script ]
| kretschmer(at)tux:~$ cat test.sh
| #!/bin/bash
|
| d=`date`
|
| psql test -c "select 'today is ' || '$d' || ', and the database says ' || now()"
`----
,----[ running the script ]
| kretschmer(at)tux:~$ ./test.sh
| ?column?
| ---------------------------------------------------------------------------------------------
| today is Sa 10. Jul 08:40:25 CEST 2010, and the database says 2010-07-10 08:40:25.248636+02
| (1 Zeile)
|
| kretschmer(at)tux:~$
`----
You got it?
