Operating Systems Linux How to create file on Linux using environment variable in the dirpath Post 302252036 by patricia1of5 on Tuesday 28th of October 2008 04:19:10 PM

Thanks

Jim,

Yes, I'd thought about System.getevn, but I was expecting to find a way to let the OS do whatever OS-specific translation was appropriate in the directory path on file creation. It's looking like that doesn't fly - maybe a shell is required to get env var translation . . . Well, I switched to using System.getenv to get the env var value and appending the rest of the directory path and that works. Thanks for taking the time to help out,

GNOME-SESSION(1)					      General Commands Manual						  GNOME-SESSION(1)

NAME
gnome-session - Starts up the GNOME desktop environment SYNOPSIS
gnome-session [--autostart=DIR] [--default-session-key=KEY] [--failsafe|-f] [--debug] DESCRIPTION
The gnome-session program starts up the GNOME desktop environment. This command is typically executed by your login manager (either gdm, xdm, or from your X startup scripts). It will load either your saved session, or it will provide a default session for the user as defined by the system administrator (or the default GNOME installation on your system). The default session is defined in the GConf keys under /desktop/gnome/session. When saving a session, gnome-session saves the currently running applications in the $XDG_CONFIG_HOME/gnome-session/saved-session directory. gnome-session is an X11R6 session manager. It can manage GNOME applications as well as any X11R6 SM compliant. OPTIONS
The following options are supported: --autostart=DIR Start all applications defined in DIR, instead of starting the applications defined in /desktop/gnome/session/default_session, or via the --default-session-key option. Multiple --autostart options can be passed. --default-session-key=KEY Sets the GConf key from which applications running a default session should be read to KEY. If not specificed, /desktop/gnome/ses- sion/default_session will be used. --failsafe gnome-session will run in fail-safe mode. User-specified applications will not be started. --debug Enable debugging code. ENVIRONMENT
gnome-session accepts all of the standard environment variables used by gnome programs, other than the SESSION_MANAGER environment vari- able. gnome-session also sets several environment variables for the use of its child processes. SESSION_MANAGER This variable is used by session-manager aware clients to contact gnome-session. DISPLAY This variable is set to the X display being used by gnome-session. Note that if the --display option is used this might be different from the setting of the environment variable when gnome-session is invoked. SEE ALSO
gnome-session-properties(1) gnome-session-save(1) gnome-wm(1) BUGS
