hey guys i need our help for my assignment to be passed tomorrow.

good day to all. im just a new member. since im a newbie in UNIX, im having trouble learning.

problem #1

Quote:

MONITORING A USER'S LOGIN TIME
DUE DATE=APRIL 26, 2011

Create a script called USERLOGTIME that computes for the total
number of hours and minutes a particular user has been logged on to the
system. The script accepts one parameter, the user id.

Sample run:
[prompt]$ LOGTIME it2015678 <enter>

User it2015678 is CRUZ Tommy H
And has logged on to the system for:
8 hours
12 minutes
from the time this script was run.

problem # 2

Quote:

RECYCLE BIN
DUE DATE=APRIL 27, 2011

Write a script called RECYCLEBIN that will follow the given
syntax:
RECYCLEBIN [-l -p ] filename/s

The specific action of each parameter in the script is
as follows:

filename/s moves the filename/s into a hidden directory called
".recyclebin" in your home directory
-l it will list the current contents of the recycle bin
or it will list the specified filename/s
-p it will purge(clean) all the contents of the recycle bin
or it will remove the specified filename/s

The script will act like a recycle bin in that instead of removing
files permanently, it moves them into a hidden folder called,".recyclebin"
in your home directory. If ".recyclebin" doesn't exist, it should be
automatically created.

Sample Runs:
a. [prompt]$ RECYCLEBIN hello.txt <enter>

Do you want the file/s to be moved to recycle bin y/n? y <enter>

[prompt]$

b. to verify if hello.txt was moved to " .recyclebin "
[prompt]$ RECYCLEBIN -l <enter>

OUTPUT: -rw-r--r-- 1 it2003456 stud .... hello.txt

[prompt]$

c. to purge
[prompt]$ RECYCLEBIN -p

Do you want all files in the recycle bin to be deleted y/n? y <enter>

[prompt]$

MACHINE PROBLEM 5
FAMILIARIZATION WITH PROCESSES
DUE DATE=APRIL 28, 2011

Create a menu-driven script called PROCESSES that will perform each of
the given requirement upon choice of a letter by a user:

[A/a]. Display all user processes and their total
[B/b]. Display all your account's processes and its total
[C/c]. Display a process or set of processes given a user id
or the a user's real world name
[D/d]. Halts a particular process given its pid
[E/e]. Exit

thank you guys. take good care!

vfs_recycle

VFS_RECYCLE(8)						    System Administration tools 					    VFS_RECYCLE(8)

NAME

       vfs_recycle - Samba VFS recycle bin

SYNOPSIS

       vfs objects = recycle

DESCRIPTION

       This VFS module is part of the samba(7) suite.

       The vfs_recycle intercepts file deletion requests and moves the affected files to a temporary repository rather than deleting them
       immediately. This gives the same effect as the Recycle Bin on Windows computers.

       The Recycle Bin will not appear in Windows Explorer views of the network file system (share) nor on any mapped drive. Instead, a directory
       called .recycle will be automatically created when the first file is deleted and recycle:repository is not configured. If
       recycle:repository is configured, the name of the created directory depends on recycle:repository. Users can recover files from the recycle
       bin. If the recycle:keeptree option has been specified, deleted files will be found in a path identical with that from which the file was
       deleted.

       This module is stackable.

OPTIONS

       recycle:repository = PATH
	   Path of the directory where deleted files should be moved.

	   If this option is not set, the default path .recycle is used.

       recycle:directory_mode = MODE
	   Set MODE to the octal mode the recycle repository should be created with. The recycle repository will be created when first file is
	   deleted. If recycle:subdir_mode is not set, MODE also applies to subdirectories.

	   If this option is not set, the default mode 0700 is used.

       recycle:subdir_mode = MODE
	   Set MODE to the octal mode with which sub directories of the recycle repository should be created.

	   If this option is not set, subdirectories will be created with the mode from recycle:directory_mode.

       recycle:keeptree = BOOL
	   Specifies whether the directory structure should be preserved or whether the files in a directory that is being deleted should be kept
	   separately in the repository.

       recycle:versions = BOOL
	   If this option is True, two files with the same name that are deleted will both be kept in the repository. Newer deleted versions of a
	   file will be called "Copy #x of filename".

       recycle:touch = BOOL
	   Specifies whether a file's access date should be updated when the file is moved to the repository.

       recycle:touch_mtime = BOOL
	   Specifies whether a file's last modified date should be updated when the file is moved to the repository.

       recycle:minsize = BYTES
	   Files that are smaller than the number of bytes specified by this parameter will not be put into the repository.

       recycle:maxsize = BYTES
	   Files that are larger than the number of bytes specified by this parameter will not be put into the repository.

       recycle:exclude = LIST
	   List of files that should not be put into the repository when deleted, but deleted in the normal way. Wildcards such as * and ? are
	   supported.

       recycle:exclude_dir = LIST
	   List of directories whose files should not be put into the repository when deleted, but deleted in the normal way. Wildcards such as *
	   and ? are supported.

       recycle:noversions = LIST
	   Specifies a list of paths (wildcards such as * and ? are supported) for which no versioning should be used. Only useful when
	   recycle:versions is enabled.

EXAMPLES

       Move files "deleted" on share to /data/share/.recycle instead of deleting them:

		   [share]
		path = /data/share
		vfs objects = recycle
		recycle:repository = .recycle
		recycle:keeptree = yes
		recycle:versions = yes

VERSION

       This man page is correct for version 3.0.25 of the Samba suite.

AUTHOR

       The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open
       Source project similar to the way the Linux kernel is developed.
