I'm new to powershell. I need to write a script which will import data for each table into separate text file.For sample table, I tried with below script:

```
    bcp -u sa por.dbo.audit out D:\tbackup\audit.dat

```

and I received below error:

```
Copy direction must be either 'in', 'out' or 'format'.
usage: C:\Program Files\Microsoft SQL Server\Client SDK\ODBC\130\Tools\Binn\bcp.exe {dbtable | query} {in | out | queryout | format} datafile

  [-m maxerrors]            [-f formatfile]          [-e errfile]
  [-F firstrow]             [-L lastrow]             [-b batchsize]
  [-n native type]          [-c character type]      [-w wide character type]
  [-N keep non-text native] [-V file format version] [-q quoted identifier]
  [-C code page specifier]  [-t field terminator]    [-r row terminator]
  [-i inputfile]            [-o outfile]             [-a packetsize]
  [-S server name]          [-U username]            [-P password]
  [-T trusted connection]   [-v version]             [-R regional enable]
  [-k keep null values]     [-E keep identity values]
  [-h "load hints"]         [-x generate xml format file]
  [-d database name]        [-K application intent]  [-l login timeout]

```

Might be it's a silly question. But, any immediate help will be appreciated
