ifp
IFP(1) General Commands Manual IFP(1) NAME
ifp - access iRiver iFP audio devices SYNOPSIS
ifp command [arguments ...] DESCRIPTION
ifp lets you manage your music on an iRiver iFP music player acting in "Manager Mode". If your player is using "UMS Mode", then you don't need this program; it will appear as new drive when you plug it in. This manual page documents the version of ifp included as an example application for the libifp library. The interface is intended to mimic the ifp binary found in the ifp-line binary package. ifp can upload or download files or directories, delete or make directories on the device, format the device, or upgrade your firmware. COMMANDS
ls [directory] List the files and directories on the device. The root directory is /. Directories are preceded with 'd' and other files with 'f'. df Display total and free space on the device. upload localfile remotefile Copy the file named localfile to the iFP device, and name it remotefile. (This is like cp.) upload localfile remotedir Copy the file named localfile to the iFP device, into remotedir. (This is like cp.) upload localdir remotedir Copy the entire directory localdir to the device, into remotedir. This copies into a subdirectory, so upload foo / puts files from the directory foo info /foo on the device. (This is like cp -R.) This uploads the entire directory, not just audio files. put localfile | localdir Upload the file or directory to the device, with the same name it has locally. If a directory is given, it is put in /. download remotefile localfile download remotefile localdir download remotedir localdir Like upload, but copies from the iFP device to your system. Some proprietary file types may not be downloaded. get remotefile | remotedir Like put, but copies files or directories from the device to your current working directory. rm [-r] file Delete (recursively) a file (or directory) on the device. rmdir dir Delete an empty directory on the device. mkdir dir Create a directory on the device. battery Display battery status of the device. typestring Display the model number of the device. firmversion Display the firmware revision currently on the device. format Reformat the device's memory. This will delete all your music. firmupdate FIRMWARE.HEX Upload the file FIRMWARE.HEX as new firmware for the device. This will not delete your music, but may have many other detrimental effects. Don't turn the device off or unplug it while the firmware is updating, and don't attempt to upload new firmware with a low battery. AUTHORS
