How to set env variable in shell

General
1

Hi,

The below “myusernam” has a password in PostgreSQL.
By using a shell object, I wanted to set PGPASSWORD env variable to avoid password authentication in Windows.

– Sync Shell
ShellCommand::::: set PGPASSWORD=mypassword & psql.exe -p 5433 -U myusername -s postgres

However, it seems that the above ‘set’ command doesn’t work.
I got “psql: FATAL: password authentication failed for user” error. It says that the env variable is not set correctly.

When I run the below command first in Windows prompt and then run “psql.exe” command, it works though.

set PGPASSWORD=mypassword

How can I set the PGPASSWORD env variable in this situation?

Thanks in advance.

Can you ‘pipe’ this like commandA | commandB?

set PGPASSWORD=mypassword | psql.exe -p 5433 -U myusername -s postgres

Sorry to say that: it is the same result.

this works:

  dim s as new Shell
  s.execute "export TEST=mytest;echo $TEST"

you will get “mytest” in the message box, meaning the “echo” command recognized it.

btw, pipe is meant to redirect A output to B input, while in this case are two different commands.

Great!!

I could manage to set env variable with following code.
System.EnvironmentVariable(“PGPASSWORD”) = “mypasswd”

Otherwise, you may want to use ‘pgpass.conf’ file to avoid password authentication but your password can be seen.

Thank you so much.

My environment is Windows. Thanks.

On Windows, use an ampersand (&) and on Linux / OS X, use a semi-colon (:wink: between the two commands instead of the pipe (|).
