You can control scm command line client properties through
the preferences.properties file. By default, this
file is stored here: ~/.jazz-scm, but you can specify
other locations by setting scm –config /path/to/other/location.
The file can contain two values: repository.timeout and password.mask.
repository.timeout
This value controls the
duration of the connection timeout between the scm executable and
the Jazz™ repository. It is set
in seconds.
password.mask
When set to True,
your password is hidden on password prompts; in other words, when -P is
not specified on the command line. If this is set to any other value,
your password is echoed.
