- 3. AOS practical programs 1) Write a C program to find whether a given file is present in current directory or not. 2) Write a C program which blocks SIGOUIT signal for 5 seconds. After 5 second process checks any occurrence of quit signal during this period, if so, it unblock the signal. Now another occurrence of quit signal terminates the program. (Use sigprocmask() and sigpending() ) 3) Write a C program that a string as an argument and return all the files that begins with that name in the current directory. For example > ./a.out foo will return all file names that begins with foo. 4) Write a C program to find file properties such as inode number, number of hard link, File permissions, File size, File access and modification time and so on of a given file using stat() system call. 5) Write a C program to create ‘n’ child processes. When all ‘n’ child processes terminates, Display total cumulative time children spent in user and kernel mode. 6) Write a C program to find file properties such as inode number, number of hard link, File permissions, File size, File access and modification time and so on of a given file using fstat() system call. 7) Write a C program to implement the following unix/linux command (use fork, pipe and exec system call). Your program should block the signal Ctrl-C and Ctrl- signal during the execution. ls -l | wc -l 8) Write a C program to create an unnamed pipe. The child process will write following three messages to pipe and parent process display it. Message1 = “Hello World” Message2 = “Hello SPPU” Message3 = “Linux is Funny” 9) Write a C program to read all txt files (that is files that ends with .txt) in the current directory and merge them all to one txt file and returns a file descriptor for the new file 10) Write a C program to map a given file in memory and display the contain of mapped file in reverse. 11) Write a C program to create a file with hole in it. 12) Write a C program to get and set the resource limits such as files, memory associated with a process. 13) Write a C program which receives file names as command line arguments and display those filenames in ascending order according to their sizes. e.g $ a.out a.txt b.txt c.txt, … 14) Write a C program to display as well as resets the environment variable such as path, home, root etc. 15) Write a C program that will only list all subdirectories in alphabetical order from current directory. 16) Write a C program to display statistics related to memory allocation system. (Use mallinfo() system call). 17) Write a C program to create variable length arrays using alloca() system call. 18) Write a C program that behaves like a shell (command interpreter). It has its own prompt say “NewShell$”. Any normal shell command is executed from your shell by starting a child process to execute the system program corresponding to the command. It should additionally interpret the following command. i) count c - print number of characters in file ii) count w - print number of words in file
- 4. iii)count l - print number of lines in file 19) Write a C program to send SIGALRM signal by child process to parent process and parent process make a provision to catch the signal and display alarm is fired.(Use Kill, fork, signal and sleep system call) 20) Write a C program to display all the files from current directory and its subdirectory whose size is greater than ’n’ Bytes Where n is accepted from user through command line. 21) Write a C program that redirects standard output to a file output.txt. (use of dup and open system call) 22) Write a C program to Identify the type (Directory, character device, Block device, Regular file, FIFO or pipe, symbolic link or socket) of given file using stat() system call. 23) Write a C program that catches the ctrl-c (SIGINT) signal for the first time and display the appropriate message and exits on pressing ctrl-c again. 24) Write a C program to implement the following unix/linux command on current directory ls –l > output.txt 25) Write a C program to display the given message ‘n’ times. (make a use of setjmp and longjmp system call) 26) Write a C program to display the last access and modified time of a given file. 27) Write a C program to move the content of file1.txt to file2.txt and remove the file1.txt from directory. 28) Write a C program which creates a child process to run linux/ unix command or any user defined program. The parent process set the signal handler for death of child signal and Alarm signal. If a child process does not complete its execution in 5 second then parent process kills child process. 29) Write a C program that print the exit status of a terminated child process.
