Linux program to transfer file from/to an android device? Do you know if there is a linux program (possibly nautilus plugin) to transfer file from/to an android device? What is in my mind is a program which does "adb push", "adb pull", and "adb shell ls" in the background and has a GUI.

Thanks,
There's QtADB which uses adb.

You can also install an SSH or ftp server on the phone and then use Nautilus with ssh://ip-or-name-of-your-phone/ or ftp://ip-or-name-of-your-phone/ URLs (you can create bookmarks in Nautilus). The cool thing about a standard SSH or ftp server on your phone is that you don't have to install anything special on the computer.

I use QuickSSHd on the phone, but there are also other SSH servers available (search the market, please).

Ftp servers I know are SwiFTP and FTPServer. I didn't test these with Nautilus yet, but they should work.
