Обсуждение: Batch: DB password with ">"

Hi,

i want to modiy the adatabse via batch script. The user has a password that contains symbols like that “g>uAks!”. The problem here is the “greater than”-symbol.

call set PGPASSFILE=%TEMP%\pgpass.conf

echo localhost:5432:postgres:postgres:7Ug^>uAks!{VA > %PGPASSFILE%

"C:\Program Files\PostgreSQL\10\bin\psql" -U postgres

psql will always fail with FATAL: User-Athentification failed. The password was read from ..\Local\Temp\pgpass.conf

If I set a Enviromentvariable and “echo” it, it will not work, because of the >-symbol.

C:\Users\hschenk>set PGPASSWORD=lalal>lala

C:\Users\hschenk>echo %PGPASSWORD%

Lalal

How can I use this with a password like this?

Hi,

single quotes, double quotes, escaping with

\ or

^ or

^\  or

\^

does not work.

echo localhost:5432:postgres:postgres:7Ug^\>uAks!{VA > %PGPASSFILE% does not escape the “>”-symbol.

echo "localhost:5432:postgres:postgres:7Ug^>uAks!{VA" > %PGPASSFILE% does not work, because psql seems not to understand the pgconf-file, does not check the file for a password and give me a pw prompt.

Best regards

Hendrik

There was a space too much between the password and the streaming operator. So the password was extended by a trailing space.

Furthermore you have to escape the >-symbol first with the carret in the windows command shell and then the escape-symbol \ for psql.

echo localhost:5432:postgres:postgres: 7Ug\^>uAks!{VA> %PGPASSFILE%

best regards
