store for environment variables across shell processes
Descriptionenvstore allows you to save environment variables into a separate store, list them, and reload them into the (other) shell again. It therefore provides a way to share them in cases where exporting to child processes is not feasible. Included is envify, a shell script which loads the environment saved with envstore and then executes the command given to it. A classic use case is MPD_HOST for clients of the Music Player Daemon. Commands to control the MPD would be wrapped with envify. If the MPD_HOST were then changed in envstore, it would automatically be used.
Upload new screenshots
Thanks for uploading more screenshots. Please note:
- Your screenshot should contain a typical scene when working with it.
- Take only a screenshot of the respective application and not of your whole desktop (unless the screenshot is meant for a window manager).
- Your screenshots must be in PNG format.
- You can upload multiple images at once.
- Your screenshot need to be approved by the moderators first. You will already see your screenshot but it will not be visible to others instantly. If moderators reject your upload you will get notified next time you visit this site (requires cookies).
- Images larger than 800x600 pixels will automatically be reduced. So don't try to capture too much detail in a screenshot. It may become unreadable. Shrink the applications window if possible.
- Screenshots are made public and can freely be used by anyone.
- Useful programs for making screenshots are shutter, ksnapshot (KDE), gimp, xwd or scrot. See the Debian wiki for more information on how to make screenshots under Debian.
- Please set your language to english so that everybody understands it. If you don't use english by default please start your application from a shell using after setting "export LANG=C".
