在批处理文件中运行命令

Question

I am trying to create a batch file to run start some micro services and database

   1 FOR /F "tokens=4 delims= " %%P IN ('netstat -a -n -o ^| findstr :1000') DO @ECHO TaskKill.exe /PID %%P
   2 FOR /F "tokens=4 delims= " %%P IN ('netstat -a -n -o ^| findstr :1001') DO @ECHO TaskKill.exe /PID %%P
   3 FOR /F "tokens=4 delims= " %%P IN ('netstat -a -n -o ^| findstr :5432') DO @ECHO TaskKill.exe /PID %%P
   4 start cd "C:\Program Files\PostgreSQL\10\bin\" & pg_ctl.exe -D "c:\Program Files\PostgreSQL\10\data" start 
    @REM to start service
   5 start javaw -jar -Dserver.port=1000 text-annotation-tool-1.0-SNAPSHOT.jar

Line 1 to 3 and Line 5 execute correctly when executed by commenting line 4.

Line 4 is to start a Postgres server in a new prompt (beacuse of the Dir change). I think the problem is with the way I have used quotes. The 'start' at the beginning and ending of line 4 serve different purpose.

Also, if I execute line 4 in different prompt, How do I close the prompt after execution (nohup equivalent)

Answer 1

There are two errors: You can't "pass" cd to the start command. And start has the quirk to interpret the first quoted parameter as the new window's title. So start "C:\\Program Files\\PostgreSQL\\10\\bin\\" ... wouldn't work, you need to supply a dummy window title. The & also seems wrong

So you need:

start "Postgres Server" "C:\Program Files\PostgreSQL\10\bin\pg_ctl.exe" -D "c:\Program Files\PostgreSQL\10\data" start

As the full path to pg_ctl.exe is supplied, there is no need for a cd . But if you want to define the default directory for the new process, you have to use the /D parameter:

start "Postgres Server" /D "C:\Program Files\PostgreSQL\10\bin" pg_ctl.exe -D "c:\Program Files\PostgreSQL\10\data" start

Unrelated, but: putting the Postgres data directory into c:\\Program Files\\ is a very bad idea. That directory has special permissions for a purpose. You should use %ProgramData% or %AppData% instead
