コマンドラインからUSBストレージをマウントしてマウント解除する

私はあなたがこれをpmount代わりに使用できると信じています。これはDebian 7.7リポジトリにあります。

使用法

$ pmount -h
Usage:

pmount [options] <device> [<label>]

  Mount <device> to a directory below /media/ if policy requirements
  are met (see pmount(1) for details). If <label> is given, the mount point
  will be /media/<label>, otherwise it will be /media/<device>.
  If the mount point does not exist, it will be created.

pmount --lock <device> <pid>
  Prevent further pmounts of <device> until it is unlocked again. <pid>
  specifies the process id the lock holds for. This allows to lock a device
  by several independent processes and avoids indefinite locks of crashed
  processes (nonexistant pids are cleaned before attempting a mount).

pmount --unlock <device> <pid>
  Remove the lock on <device> for process <pid> again.

Options:
  -r          : force <device> to be mounted read-only
  -w          : force <device> to be mounted read-write
  -s, --sync  : mount <device> with the 'sync' option (default: 'async')
  -A, --noatime
                mount <device> with the 'noatime' option (default: 'atime')
  -e, --exec  : mount <device> with the 'exec' option (default: 'noexec')
  -t <fs>     : mount as file system type <fs> (default: autodetected)
  -c <charset>: use given I/O character set (default: 'utf8' if called
                in an UTF-8 locale, otherwise mount default)
  -u <umask>  : use specified umask instead of the default (only for
                file sytems which actually support umask setting)
  --fmask <fmask>
                use specified fmask
  --dmask <dmask>
                use specified dmask
  -p <file>, --passphrase <file>
                read passphrase from file instead of the terminal
                (only for LUKS encrypted devices)
  -d, --debug : enable debug output (very verbose)
  -h, --help  : print this help message and exit successfuly
  -V, --version
                print version number and exit successfully
