Commands:
=========
- start Start a new SALOME instance.
+ start Start a new SALOME instance. Start a single SALOME_Session_Server_No_Server
+ process with environment relevant to the application and hosting all servants in it.
context Initialize SALOME context. Current environment is extended.
shell Initialize SALOME context, attached to the last created SALOME
instance if any, and executes scripts passed as command arguments.
User works in a Shell terminal. SALOME environment is set but
application is not started.
- connect Connect a Python console to the active SALOME instance.
- kill <port(s)> Terminate SALOME instances running on given ports for current user.
- Port numbers must be separated by blank characters.
- killall Terminate *all* SALOME running instances for current user.
- Do not start a new one.
test Run SALOME tests.
info Display some information about SALOME.
doc <module(s)> Show online module documentation (if available).
Module names must be separated by blank characters.
help Show this message.
+ remote run command in SALOME environment from remote call, ssh or rsh.
+ withsession Start a new SWS SALOME instance with multiple servers hosting all servants.
+ connect In SWS context, Connect a Python console to the active SALOME instance.
+ kill <port(s)> In SWS context, Terminate SALOME instances running on given ports for current user.
+ Port numbers must be separated by blank characters.
+ killall Terminate *all* SALOME running SWS instances for current user.
+ Do not start a new one.
If no command is given, default is start.
--config=<file,folder,...>
==========================
Initialize SALOME context from a list of context files and/or a list
- of folders containing context files. The list is comma-separated, whithout
+ of folders containing context files. The list is comma-separated, without
any blank characters.
