| # Command Line Options Command line options to automate KeePass tasks.

You can pass a file path in the command line in order to tell KeePass to open this file immediately after startup.

Switches can be either prefixed using a minus (`-`) or two minus characters (`--`). On Windows, a slash (`/`) is another alternative. The prefixes are equivalent; it doesn't matter which one you use.

Database file. The database file location is passed as argument. Only one database file is allowed. If the path contains a space, it must be enclosed in quotes (").

Password. Passwords can be passed using the `-pw:` option. In order to pass 'abc' as password, you would add the following argument to the command line: `-pw:abc`. Note that there must be no space between the '`:`' and the password. If your password contains a space, you must enclose it in quotes. For example: `-pw:"my secret password"`.

Using the `-pw:` option is not recommended, because of security reasons (the operating system allows reading the command line options of other applications).

When passing the `-pw-stdin` option, KeePass reads the password from the StdIn stream.

Key file. For supplying the key file location, the `-keyfile:` switch exists. The same rules as above apply, just that you specify the key file location: `-keyfile:D:\pwsafe.key`. You also need to quote the value, if it contains a space, tab or other whitespace characters.

Pre-selection. In order to just pre-select a key file, use the `-preselect:` option. For example, if you lock your database with a password and a key file, but just want to type in the password (so, without selecting the key file manually), your command line would look like this:

    KeePass.exe "C:\My Documents\MyDatabase.kdb" -preselect:C:\pwsafe.key

KeePass would then show a prompt for the password for the database, but in the key file list, the `C:\pwsafe.key` file is selected already. When using the `-preselect:` switch, KeePass by default activates the key file switch and sets the focus to the password edit window.

Note the difference! The `-preselect:` switch just pre-selects the key file for you and displays the login prompt. In contrast, the `-keyfile:` switch doesn't prompt you for the (maybe missing) password.

Other. The `-minimize` command line argument makes KeePass start up minimized.

The `-auto-type` command line argument makes other already opened KeePass instances perform a global auto-type.

Additionally, the `-useraccount` switch is supported. If specified, the current user account credentials will be used.
The `-iocredfromrecent` switch makes KeePass load file system credentials (not database key) from the most recently used files list. Alternatively, the file system credentials can be specified using the `-iousername:` and `-iopassword:` parameters. The optional `-ioiscomplete` switch tells KeePass that the path and file system credentials are complete (the 'Open URL' dialog will not be displayed then).
The `-pw-enc:` parameter is similar to `-pw:`, but it requires the password to be encrypted. Encrypted passwords can be generated using the `{PASSWORD_ENC}` placeholder.
The `-entry-url-open` option makes other already opened KeePass instances search for an entry and open its URL. The entry is identified by its UUID, which you can pass as `-uuid:` command line parameter.
Analogously to the `-auto-type` option, `-auto-type-selected` performs auto-type for the currently selected entry.
The path of the local configuration file can be changed using the `-cfg-local:` command line parameter.

The order of the arguments is arbitrary.

## Usage Examples

Open the database file 'C:\My Documents\MyDatabase.kdb' (KeePass will prompt you for the password and/or key file location):

    KeePass.exe "C:\My Documents\MyDatabase.kdb"

If you got a database that is locked with a password 'abc', you could open it like this:

    KeePass.exe "C:\My Documents\MyDatabaseWithPw.kdb" -pw:abc

If your USB stick always mounts to drive F: and you've locked your database with a key file on the USB stick, you could open your database as follows:

    KeePass.exe "C:\My Documents\MyDatabaseWithFile.kdb" -keyfile:F:\pwsafe.key

If you've locked your database using a password and a key file, you can combine the two switches and open your database as follows:

    KeePass.exe "C:\My Documents\MyDatabaseWithTwo.kdb" -pw:abc -keyfile:F:\pwsafe.key

You have locked your database using a password and a key file, but only want to have the key file pre-selected (i.e. you want to get prompted for the password), your command line would look like this:

    KeePass.exe "C:\My Documents\MyDatabaseWithTwo.kdb" -preselect:F:\pwsafe.key

## Starting KeePass using a Batch File

Batch files can be used to start KeePass. Mostly you want to specify some of the parameters listed above. You can theoretically simply put the command line (i.e. application path and parameters) into the batch file, but this is not recommended as the command window will stay open until KeePass is closed. The following method is recommended instead:

    START "" KeePass.exe ..\MyDb.kdb -pw:MySecretPw

This `START` command will run KeePass (which opens the `..\MyDb.kdb` file using `MySecretPw` as password). KeePass is assumed to be in the same directory (working directory) as the batch file, otherwise you need to specify a different path.

`START` executes the given command line and immediately exits, i.e. it doesn't wait until the application is terminated. Consequently, the command window will disappear after KeePass has been started.

Please note the two quotes (`"`) after the `START` command. These quotes are required if the application path contains quotes (in the example above, the quotes could also be removed). If you want to learn more about the `START` command syntax, type `START /?` into the command window.

## Closing/Locking KeePass using a Batch File

To close all currently running KeePass instances, call `KeePass.exe` with the `'--exit-all'` parameter:

    KeePass.exe --exit-all

All KeePass windows will attempt to close. If a database has been modified, KeePass will ask you whether you want to save or not. If you wish to save in any case (i.e. a forced exit without any confirmation dialog), enable the 'Automatically save database on exit and workspace locking' option in 'Tools' -> 'Options' -> tab 'Advanced'.

The KeePass instance that has been created by the command above is not visible (i.e. it does not show a main window) and will immediately terminate after sending close requests to the other instances.

The `--lock-all` and `--unlock-all` command line options lock/unlock the workspaces of all other KeePass instances.
