I need to write a C program (not a C++ program) that allows some tasks to be preformed automatically from a menu-driven interface. Automate the following tasks:
1. Rename a file
2. Delete a file or a directory
3. Output Process Information
4. Execute “mode 644 ls -l”
5. Exit
I need to know what steps should I follow to achieve the result. is it possible to ask the user to enter all the names and commands in 1 line or I should ask him one by one.
thank you
open, creat, read, write, lseek and close
Are they all primitive?
:confused:

Hi,
I'm new to UNIX system calls. Can someone share your knowledge as to how exactly system calls should be executed?
Can they be typed like commands such as mkdir on the terminal itself? Also, are there any websites which will show me an example of the output to expect when a system call like... (1 Reply)

Hi friends,
I have three questions.
1) What are system calls?
2) Is it necessary that system calls be in c language (in unix operating system)?
3) Importance of c language when programming in unix environment???
Looking forward to your wonderful replies!

Hi friends,
I hope everyone is fine and doing well. I queried in my previous thread about the low-level qualities of C/C++ languages.I really thank you people for explaining, it was really helpful. One more ambiquity that I have in my mind is regarding the unix system calls like open, creat,... (1 Reply)

sysman_menu
sysman_menu(8) System Manager's Manual sysman_menu(8)NAME
sysman_menu - Graphical interface to run system management tasks
SYNOPSIS
/usr/sbin/sysman [-ui cui | gui] [-display displayname] [-menu]
/usr/sbin/sysman [-accel] <accelerator> [arguments]
/usr/sbin/sysman [-menu] <name> [arguments]
/usr/sbin/sysman [-menu] -list
/usr/sbin/sysman [-menu] -help | -h
/usr/sbin/sysman -focus hostname
OPTIONS
Specifies the user interface to be invoked. The choices are: Specifies command line interface. Specifies graphical user interface. Speci-
fies the display screen on where sysman_menu displays its window. If the display option is not specified, sysman_menu uses the display
screen specified by your DISPLAY environment variable. The display option has the format hostname:server.number. The default is :0.0. For
more information, see the X(1X) reference page. In a TruCluster environment, some management tasks effect the cluster as a whole and some
are local to a specific cluster member. If a task requires focus, the "Choose a host to manage" dialog box will be displayed. To launch
the task directly, bypassing this dialog box, you can specify the -focus option. Directly invokes the task with that accelerator. Any
arguments are passed on to the task itself. Use sysman -list for a list of the accelerators.
If the accelerator is for a branch of the menu and not an executable task, then the menu hierarchy is expanded to display the con-
tents of the specified branch. Same as -accel option but the name of the task as displayed in the SysMan Menu is specified. For
example, sysman -menu "Manage local users". Any arguments are passed on to the task itself.
The name is for a branch of the menu and not an executable task, then the menu hierarchy is expanded to display the contents of the
specified branch. Displays a list of all the tasks that can be run from the SysMan Menu and their accelerators. Displays help for
the SysMan Menu.
DESCRIPTION
SysMan Menu is used by the system administrator to obtain system management data and run selected system management tasks. SysMan Menu pro-
vides a menu of system management tasks in a tree type display, with branches of management categories and leaves of actual tasks. Select-
ing a leaf or tasks invokes a task, which displays a dialog for performing the task.
SysMan Menu and its associated tasks can be run on an X Windows display, a terminal with curses capability, locally on a PC, or from a Web
browser. For detailed information in running SysMan Menu from a PC or a Web browser, please use your Web browser and go to:
http://your_machine_name:2301/SYSMAN/index.html.
Online help is available for the SysMan Menu. To get help, select the Help button.
RESTRICTIONS
You must have root privileges to perform most tasks with this application. You can grant root privileges for specific users or groups of
users using the Division of Privileges (DOP) application. See the dop(8) reference page and the online help in the sysman dopconfig appli-
cation for additional information.
You must have the root privileges to execute some of the tasks on the SysMan Menu.
EXAMPLES
The following example shows how to launch the Manage local users task from the command line using an accelerator name: sysman -accel users
The following example shows how to invoke SysMan Menu in curses mode: sysman -ui cui The following example shows how to get a listing of
tasks and their accelerators: sysman -list The following example, displays the status of the NFS related daemons on a remote cluster mem-
ber: sysman -focus nfs_config_status
