-c --command

-c command or--command command runs one command and exits. This is useful in shell scripts.

Use either:

• A command string that can be completely parsed by the server that does not contain features specific to vsql

• A single meta-command

You cannot mix SQL and vsql meta-commands. You can, however, pipe the string into vsql as shown:

echo "\\timing\\\\select * from t" | ../Linux64/bin/vsql
                Timing is on.
                i | c | v
                ---+---+---
                (0 rows)
