SUSE笔记：eject的使用

wandering 发表于 2007-03-29 23:22:49

正好要看一张备份了mp3的DVD光盘，想到在命令行下如何把光驱弹出呢？弹出光驱用英文表示是eject，在很多软件的菜单中可以看到。于是，直接在shell下键入eje+<Tab>，哇，真的有eject命令啊～

shell> eject --help
Eject version 2.1.0 by Jeff Tranter ([email protected])
Usage:
  eject -h                              -- display command usage and exit
  eject -V                              -- display program version and exit
  eject [-vnrsfq] [<name>]              -- eject device
  eject [-vn] -d                        -- display default device
  eject [-vn] -a on|off|1|0 [<name>]    -- turn auto-eject feature on or off
  eject [-vn] -c <slot> [<name>]        -- switch discs on a CD-ROM changer
  eject [-vn] -t [<name>]               -- close tray
  eject [-vn] -T [<name>]               -- toggle tray
  eject [-vn] -x <speed> [<name>]       -- set CD-ROM max speed
Options:
  -v    -- enable verbose output
  -n    -- don't eject, just show device found
  -r    -- eject CD-ROM
  -s    -- eject SCSI device
  -f    -- eject floppy
  -q    -- eject tape
  -p    -- use /proc/mounts instead of /etc/mtab
  -m    -- do not unmount device even if it is mounted
Long options:
  -h --help   -v --verbose       -d --default
  -a --auto   -c --changerslot  -t --trayclose  -x --cdspeed
  -r --cdrom  -s --scsi  -f --floppy
  -q --tape   -n --noop  -V --version
  -p --proc   -m --no-unmount -T --traytoggle
Parameter <name> can be a device file or a mount point.
If omitted, name defaults to `/dev/cdrom'.
By default tries -r, -s, -f, and -q in order until success.

用 eject -vn 可以看到有哪些移动设备，很方便。

shell> eject -vn
eject: using default device `/dev/cdrom'
eject: device name is `/dev/cdrom'
eject: expanded name is `/dev/cdrom'
eject: `/dev/cdrom' is a link to `/dev/hda'
eject: `/dev/hda' is mounted at `/media/New'
eject: device is `/dev/hda'
eject: exiting due to -n/--noop option

弹出光驱：

shell> eject -v /dev/cdrom
