Can anyone enlighten me as to why simple cli file manipulation command 'cp' won't work on .gvfs mount bluetooth phone? A simple clarification would be greatly appreciated. I found that gvfs-copy worked, after I asked bluetooth to browse the device, (phone). Thank you. Following, some cli stuff I tried.

user@cpu:~$ alias f
alias f='sed "s/$ACCOUNT_NAME/\$USER/g"
user@cpu:~$ cat ~/.bashrc | grep ACCOUNT_NAME
ACCOUNT_NAME=`cat /etc/passwd | grep 1000 | cut -d: -f1` # SET $ACCOUNT_NAME
user@cpu:~$ ls -al ~/.gvfs/LG440G/Audio/ | head -n4 | f

(gvfs-copy:18480): GLib-GIO-CRITICAL **: g_cancellable_release_fd: assertion `G_IS_CANCELLABLE (cancellable)' failed
user@cpu:~$

This last attempt via gvfs-copy, though outputing "'G_IS_CANCELLABLE (cancellable)' failed", worked. What's up with normal 'cp' command?

Why "su -c"? Have you tried:

Same, ( cp: accessing `.gvfs/LG440G/Audio/': Permission denied )
Only gvfs-copy seems to work. Thanks for the reply DL.
