QuiteRSS works on Linux. I set it up today to run on two different Linux machines from the same flash card. So now, I can take RSS with me on the flash card and all the feeds look the same on either computer.

The method: Make symbolic links. The program remains installed on each machine, but the feeds will now be stored on removable media.

1. Copy the database files to the flash drive.


2. Backup original files.

sudo mv /usr/bin/quiterss /usr/bin/quiterss.bak  

3. Create symbolic link so computer will look at flash card for the feeds.

sudo ln -s /media/{your-username}/FLASH1/QuiteRSS/QuiteRss/QuiteRss /usr/bin/quiterss

Note: If I opened QuiteRSS between the two steps, the program creates a new folder automatically and breaks this setup.
