if i decompose the line in two (under SHELL fish):
>$ hdiutil attach -nomount ram://204800
/dev/disk4
$ diskutil erasevolume HFS+ "RamDisk" /dev/disk4
Started erase on disk4
Unmounting disk
Erasing
Initialized /dev/rdisk4 as a 100 MB case-insensitive HFS Plus volume
Mounting disk
Finished erase on disk4 RamDisk
it's OK then i was hopping doing :
$ set monVolume (hdiutil attach -nomount ram://204800)
>$ diskutil erasevolume HFS+ "RamDisk" $monVolume
Unable to find disk for /dev/disk5
was working correctly, but not.
strange the "Unable to find disk for /dev/disk5" because :
$ lal /dev/disk*
brw-r----- 1 root operator 1, 0 20 fév 15:31 /dev/disk0
brw-r----- 1 root operator 1, 1 20 fév 15:31 /dev/disk0s1
