Shebang for psql

问题

I'm trying to write PostgreSQL script(s) but having a problem with shebang line

#! /usr/bin/psql [ psql_args_here ] -f

select now();

This gives me error as if I just entered psql without any arguments in command line. How do I do it right?

回答1:

The problem is that psql don't skip the first line of the file.

You could try

#! /bin/sh
exec sh -c "tail -n +3 $0 | psql -f -"

select now();

or simply

#! /bin/sh
psql << E_O_SQL

select now();

E_O_SQL

There is a even better solution. The first line should be:

--() { :; }; exec psql -f "$0"

It works as a regular shebang #!
