LISTING OF FILES USING UNIX COMMAND
AIM:
To write a c program to list the files using UNIX commands.
ALGORITHM:
STEP 1: Start the program
STEP 2: Create the new child process using the fork ( ) in UNIX
STEP 3: List the files available in specified directory using execl function.
STEP 4: The list of available files are displayed in the terminal.
STEP 5: Stop the program.
PROGRAM:
#include<stdio.h>
#include<unistd.h>
main()
{
int pid;
pid=fork();
if(pid==0)
{
printf("execution starts\n");
execl("/bin/ls","ls","-1",(char*)0);
printf("execution did not work\n");
}
else
{
wait(0);
printf("parent:is completed in child");
}
}
OUTPUT:
$cc list.c
$./a.out
Execution starts
a.c
child.c
tharu.sh
sam.sh
y.tab.h
parent is completed in child
