propset

propset

Synopsis
propset [ -s | --shell ] <name> [ <value> ] Set or remove a property
Details
The propset command sets and removes properties in either the System property space or (if -s or --shell is used) Shell property space. If both <name> and <value> are supplied, the property <name> is set to the supplied <value>. If just <name> is given, the named property is removed.

The System property space consists of the properties returned by "System.getProperty()". This space are currently isolate-wide, but there are moves afoot to make it proclet specific. The Shell property space consists of properties stored by each Shell instance. This space is is separate from an shell interpreter's variable space, and persists over changes in a Shell's interpreter.

The 'set' command is an alias for 'propset', but if you are using the 'bjorne' interpreter the 'set' alias is obscured by the POSIX 'set' builtin command which has incompatible semantics. Hence 'propset' is the recommended alias.
