So, I have an expect script (let's call it expect.exp) that takes 3 arguments. It logs into a remote server, runs a set of commands, then hands control over to the user by the "interact" command. If I call this script from the command line, it works properly.
Now I'd like to apply this script... (2 Replies)

umount
UMOUNT(8) Linux Programmer's Manual UMOUNT(8)NAME
umount - unmount file systems
SYNOPSIS
umount [-hV]
umount -a [-dflnrv] [-t vfstype] [-O options]
umount [-dflnrv] {dir|device}...
DESCRIPTION
The umount command detaches the file system(s) mentioned from the file hierarchy. A file system is specified by giving the directory where
it has been mounted. Giving the special device on which the file system lives may also work, but is obsolete, mainly because it will fail
in case this device was mounted on more than one directory.
Note that a file system cannot be unmounted when it is `busy' - for example, when there are open files on it, or when some process has its
working directory there, or when a swap file on it is in use. The offending process could even be umount itself - it opens libc, and libc
in its turn may open for example locale files. A lazy unmount avoids this problem.
Options for the umount command:
-V Print version and exit.
-h Print help message and exit.
-v Verbose mode.
-n Unmount without writing in /etc/mtab.
-r In case unmounting fails, try to remount read-only.
-d In case the unmounted device was a loop device, also free this loop device.
-i Don't call the /sbin/umount.<filesystem> helper even if it exists. By default /sbin/umount.<filesystem> helper is called if one
exists.
-a All of the file systems described in /etc/mtab are unmounted. (With umount version 2.7 and later: the proc filesystem is not
unmounted.)
-t vfstype
Indicate that the actions should only be taken on file systems of the specified type. More than one type may be specified in a
comma separated list. The list of file system types can be prefixed with no to specify the file system types on which no action
should be taken.
-O options
Indicate that the actions should only be taken on file systems with the specified options in /etc/fstab. More than one option type
may be specified in a comma separated list. Each option can be prefixed with no to specify options for which no action should be
taken.
-f Force unmount (in case of an unreachable NFS system). (Requires kernel 2.1.116 or later.)
-l Lazy unmount. Detach the filesystem from the filesystem hierarchy now, and cleanup all references to the filesystem as soon as it is
not busy anymore. (Requires kernel 2.4.11 or later.)
--no-canonicalize
Don't canonicalize paths. For more details about this option see the mount(8) man page.
THE LOOP DEVICE
The umount command will free the loop device (if any) associated with the mount, in case it finds the option `loop=...' in /etc/mtab, or
when the -d option was given. Any pending loop devices can be freed using `losetup -d', see losetup(8).
NOTES
The syntax of external umount helpers is:
/sbin/umount.<suffix> {dir|device} [-nlfvr]
where the <suffix> is filesystem type or a value from "uhelper=" mtab option.
The uhelper (unprivileged umount helper) is possible to used when non-root user wants to umount a mountpoint which is not defined in the
/etc/fstab file (e.g devices mounted by HAL).
FILES
/etc/mtab table of mounted file systems

HISTORY
A umount command appeared in Version 6 AT&T UNIX.
AVAILABILITY
The umount command is part of the util-linux-ng package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
