You can use 'ps' to "report a snapshot of the current processes" (the 'man'
page description) and 'grep' to filter the output. On my system:
$ ps x | grep gvfsd
16276 ? Sl 0:00 /usr/lib/gvfs/gvfsd
16299 ? Sl 0:00 /usr/lib/gvfs/gvfsd-fuse /run/user/1000/gvfs -f -o

17763 ? Sl 0:00 /usr/lib/gvfs/gvfsd-trash --spawner :1.11

17771 ? Sl 0:00 /usr/lib/gvfs/gvfsd-burn --spawner :1.11
/org/gtk/gvfs/exec_spaw/1
17962 ? Sl 0:05 /usr/lib/gvfs/gvfsd-metadata
