kwalletcli - command line interface to the KDE Wallet
kwalletcli [-q] -hV
kwalletcli [-q] -f folder -e entry [-P | -p password]
The kwalletcli utility is a command line interface to KWallet. It will
only work if KDE is running (DCOP). kwalletcli can be used to get
password entries from the Wallet, or to write them there.
The options are as follows:
-e entry Define the key (entry) to use when accessing the Wallet.
-f folder Set the folder to use when accessing the Wallet. Mandatory.
-h Display the usage.
-P Read the password to write from standard input.
-p password Write password into the designated location in the Wallet.
-q Be more quiet. In combination with -V, do not display
-V Display the kwalletcli version information.
Default mode of operation, that is, unless -P or -p are used, is to read
the password from the Wallet and print it to standard output as-is,
without any trailing newline.
All input and output is assumed to be in UTF-8.
The kwalletcli utility exits 0 on success or >0 if an error occurred:
1 The entry specified cannot be found (read access).
2 The usage was shown.
3 The Wallet could not be opened. May be a missing DCOP connection.
Perhaps DISPLAY is not set.
4 The folder specified cannot be found (read access).
5 The folder specified cannot be opened.
6 The value to the key specified could not be retrieved.
8 An error occured trying to write the value.
The exit codes 1 and 4, on reading, are not fatal; they merely indicate
that the folder or entry specified does not exist. The other errors are
fatal and may be used to indicate the user that the KWallet should not be
used any more during the current session.

Do not use -p password to store it, unless you absolutely must. It is a
security risk, because the command line invocation is public information
in a normal Unix environment. Use -P instead and provide the password on
Beware of trailing newlines, especially outside of mksh(1) scripts!
If DISPLAY is not set, not valid, or kdeinit or kdeinit4 cannot start for
other reasons, kwalletcli may not recover gracefully. In KDE 4 versions,
this may even result in a Segmentation fault. The author does not know
of a way to catch this early; patches are welcome.
There is no way (yet) to set a wallet other than the default wallet.
While this is a possible enhancement to the kwalletcli CLI, there is no
feasible way to expose this functionality to the various front-ends, such
as pinentry-kwallet(1), anyway, so the priority of fixing this is low.
