7843 Directory Management
7843 Directory Management Tired of using existing badly written operating systems, Hieu decided to write his new one. Of course, his new operating system will be awesome, bug-free, fast and easy to use. He has finished most of the work, and now he is asking you to do one lasttask: Implement a directory manager. Initially, Hieu’s computer directory is empty. The current directory is the root directory. The directory manager keeps the directory in a rooted-tree structure. In each directory, the children are sorted in lexicographical order. He can do one of the following actions: • MKDIR s: create a child directory named s inside the current directory where s is a string. – If the current directory already contains a child directory named s, print “ERR” and do nothing. – Otherwise, print “OK” • RM s: remove a child directory named s inside the current directory where s is a string. Figure 1 – If there is no child directory named s, print “ERR”. Otherwise, print “OK”. • CD s: change the current directory to a child directory named s where s is a string. – If s is equal to the string “..” and the current directory is the root directory, print “ERR” and do nothing. – If s is equal to the string “..” and the current directory is not the root direc- tory, then you need to change the current directory to the parent directory Figure 2 and print “OK”. – If there is no child directory named s, print “ERR” and do nothing. – If there is a child directory named s then you need to change the current directory to s and print “OK”. -
Commands to Control Device
Commands to Control Device New OTA firmware upgrade command. To try it via over-the-air update, use these commands: > fwe > fwd B6FMA186 The board will reboot after the first command, this is normal. After the second command wait 1-3 minutes (seems like a long time). After it resets again, go back to BlueFruit and press "info" the software should be 3.0.186 The default wakeup interval is still 4 hours (14400 seconds). To configure a unit for a different wakeup interval: >wakt 600 (this would be 60*10 = 10 minutes) No beeps (Command to turn off the beeps) nvap 6 120000 14400000 15000 5000 0 223 1 3 Command to Restore Beeps nvap 6 120000 14400000 15000 5000 0 223 1 65535 Main Menu commands ---- SubMenus -------------------------- >i - I2C menu >l - Log menu >M - Modem menu ---- Device Control Cmds --------------- >D [n] - set debug level to [n] >info - Show device info >cota - CDMA OTA reprovision >svrm [name] - Set server main >nvmr - Non-volatile memory revert >t - show system uptime >rst - Hard reset ---- General Cmds ---------------------- >c [str] - Execute remote command manually >batq - Query battery state >slp - Go to sleep immediately >slpt [n] - Set sleep timeout to [n] seconds >wakt [n] - Set wake timeout to [n] hours >sus - Suspend immediately >sts - Show statistics and send to server >bt [n] - Bluetooth disable/enable: n=0/1 >dsms [n] - DebugSMS configure 0/1=disabled/enabled >wss [p] [s] - WiMM Server Send [p]ort, [s]tring >wsr - WiMM Server Recv ---- Pos/Log Cmds ---------------------- >pn - Position now >plc {i} {t} - Position log ctrl, [i]nterval, [t]ripId Stop Logging >pla {i} {t} - Position log auto, [i]nterval, [t]ripId >plb {n} - Position log batch [n] records >ple - Position log erase --- Alarm Cmds ------------------------ >alm [m] - Alarm mode: m=0/1/2: Off/On/FireNow ---- Firmware Cmds --------------------- >fwd [v] - Firmware Download (WIMM{v}.hex) >fwl {i} - Firmware Launch (i=0/1: ImgA/B) >fwe - Firmware Erase (ImgB) To change the alarm delay You must be running firmware 145 or later. -
KDE 2.0 Development, Which Is Directly Supported
23 8911 CH18 10/16/00 1:44 PM Page 401 The KDevelop IDE: The CHAPTER Integrated Development Environment for KDE by Ralf Nolden 18 IN THIS CHAPTER • General Issues 402 • Creating KDE 2.0 Applications 409 • Getting Started with the KDE 2.0 API 413 • The Classbrowser and Your Project 416 • The File Viewers—The Windows to Your Project Files 419 • The KDevelop Debugger 421 • KDevelop 2.0—A Preview 425 23 8911 CH18 10/16/00 1:44 PM Page 402 Developer Tools and Support 402 PART IV Although developing applications under UNIX systems can be a lot of fun, until now the pro- grammer was lacking a comfortable environment that takes away the usual standard activities that have to be done over and over in the process of programming. The KDevelop IDE closes this gap and makes it a joy to work within a complete, integrated development environment, combining the use of the GNU standard development tools such as the g++ compiler and the gdb debugger with the advantages of a GUI-based environment that automates all standard actions and allows the developer to concentrate on the work of writing software instead of managing command-line tools. It also offers direct and quick access to source files and docu- mentation. KDevelop primarily aims to provide the best means to rapidly set up and write KDE software; it also supports extended features such as GUI designing and translation in con- junction with other tools available especially for KDE development. The KDevelop IDE itself is published under the GNU Public License (GPL), like KDE, and is therefore publicly avail- able at no cost—including its source code—and it may be used both for free and for commer- cial development. -

Fundamentals of UNIX Lab 5.4.6 – Listing Directory Information (Estimated Time: 30 Min.)
Fundamentals of UNIX Lab 5.4.6 – Listing Directory Information (Estimated time: 30 min.) Objectives: • Learn to display directory and file information • Use the ls (list files) command with various options • Display hidden files • Display files and file types • Examine and interpret the results of a long file listing • List individual directories • List directories recursively Background: In this lab, the student will use the ls command, which is used to display the contents of a directory. This command will display a listing of all files and directories within the current directory or specified directory or directories. If no pathname is given as an argument, ls will display the contents of the current directory. The ls command will list any subdirectories and files that are in the current working directory if a pathname is specified. The ls command will also default to a wide listing and display only file and directory names. There are many options that can be used with the ls command, which makes this command one of the more flexible and useful UNIX commands. Command Format: ls [-option(s)] [pathname[s]] Tools / Preparation: a) Before starting this lab, the student should review Chapter 5, Section 4 – Listing Directory Contents b) The student will need the following: 1. A login user ID, for example user2, and a password assigned by their instructor. 2. A computer running the UNIX operating system with CDE. 3. Networked computers in classroom.

System Calls System Calls
System calls We will investigate several issues related to system calls. Read chapter 12 of the book Linux system call categories file management process management error handling note that these categories are loosely defined and much is behind included, e.g. communication. Why? 1 System calls File management system call hierarchy you may not see some topics as part of “file management”, e.g., sockets 2 System calls Process management system call hierarchy 3 System calls Error handling hierarchy 4 Error Handling Anything can fail! System calls are no exception Try to read a file that does not exist! Error number: errno every process contains a global variable errno errno is set to 0 when process is created when error occurs errno is set to a specific code associated with the error cause trying to open file that does not exist sets errno to 2 5 Error Handling error constants are defined in errno.h here are the first few of errno.h on OS X 10.6.4 #define EPERM 1 /* Operation not permitted */ #define ENOENT 2 /* No such file or directory */ #define ESRCH 3 /* No such process */ #define EINTR 4 /* Interrupted system call */ #define EIO 5 /* Input/output error */ #define ENXIO 6 /* Device not configured */ #define E2BIG 7 /* Argument list too long */ #define ENOEXEC 8 /* Exec format error */ #define EBADF 9 /* Bad file descriptor */ #define ECHILD 10 /* No child processes */ #define EDEADLK 11 /* Resource deadlock avoided */ 6 Error Handling common mistake for displaying errno from Linux errno man page: 7 Error Handling Description of the perror () system call. -

Using the GNU Debugger (Gdb) a Debugger Is a Very Useful Tool for Finding Bugs in a Program
Using the GNU debugger (gdb) A debugger is a very useful tool for finding bugs in a program. You can interact with a program while it is running, start and stop it whenever, inspect the current values of variables and modify them, etc. If your program runs and crashes, it will produce a ‘core dump’. You can also use a debugger to look at the core dump and give you extra information about where the crash happened and what triggered it. Some debuggers (including recent versions of gdb) can also go backwards through your code: you run your code forwards in time to the point of an error, and then go backwards looking at the values of the key variables until you get to the start of the error. This can be slow but useful sometimes! To use a debugger effectively, you need to get the compiler to put extra ‘symbol’ information into the binary, otherwise all it will contain is machine code level – it is much more useful to have the actual variable names you used. To do this, you use: gfortran –g –O0 mycode.f90 –o mybinary where ‘-g’ is the compiler option to include extra symbols, -O0 is no optimization so the code is compiled exactly as written, and the output binary is called ’mybinary’. If the source files and executable file is in the same directory, then you can run the binary through the debugger by simply doing: gdb ./mybinary This will then put you into an interactive debugging session. Most commands can be shortened (eg ‘b’ instead of ‘break’) and pressing ‘enter’ will repeat the last command. -
