this is the code you should use from already existing shell i created .
Just gothrough the programand execute that command.and execute in linux. It takes the command from the user and execute.
#include<stdio.h>i
#include<stdlib.h>
#include<string.h>
int main()
{
//cmd1 is the ,hr variable which holds the commands
char cmd1[10];
printf("Enter the command without options like ls or date");
scanf("%s",&cmd1);
printf("%s\n",cmd1);
//system function is used for to run the unix commad, it use
system(cmd1);
return 0;
}
#include<stdlib.h>
int main()
{
//cmd1 is the ,hr variable which holds the commands
char cmd1[10];
printf("Enter the command without options like ls or date");
scanf("%s",&cmd1);
//system function is used for to run the unix commad, it use
system(cmd1);
return 0;
}
Solution: -
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_CMN_LEN 100
int main(int argc, char *argv[])
{
char cmd[MAX_CMN_LEN] = "", **p;
if (argc < 2) /*no command specified*/
{
fprintf(stderr, "Usage: ./program_name terminal_command
...\n");
exit(EXIT_FAILURE);
}
else
{
strcat(cmd, argv[1]);
for (p = &argv[2]; *p; p++)
{
strcat(cmd, " ");
strcat(cmd, *p);
}
system(cmd);
}
return 0;
}
how to run programm:-
1). open up a terminal and compile the program
2). run it (for example in Ubuntu) ./program_name comman_name -anything - anything
example: ./a.out ls
Output:- It will print all current directory folder and file name.

Thanks :)
this is the code you should use from already existing shell i created . Just gothrough...
The original code using the gets() function is written below. You need to do (a) change the provided code so that you now use fgets() function to obtain input from the user instead of gets(), (b) make any other necessary changes in the code because of using fgets() function, and (c) fill in the code for the execute() function so that the whole program works as expected (a simple shell program). Note: part c is already done, and the execute...
Edit the code (shell.c) given to do the tasks asked! will rate for correct answer! Also, include a screen shot of the output and terminal window of each command you used. Read carefully to do this task please. shell.c code given below. #include <stdio.h> #include <unistd.h> #include <stdlib.h> #include <sys/wait.h> #include <string.h> int main() { int PID; char lineGot[256]; char *cmd; while (1){ printf("cmd: "); fgets(lineGot, 256, stdin); // Get a string from user (includes \n) cmd = strtok(lineGot, "\n");...

If you already answer this question, please skip, thanks C Programming. Fill in ... This program will be called with one command line argument that contains a string followed by an asterisk and an integer. Print out the string as many time as indicated by the integer. For example, when called as prog Hi*3, you print HiHiHi. Hint: Look for the '*' starting from the back of the string. len = strlen(arg) gives you the string length. When you have...
Please help run all the examples correctly and only the examples without extra things in or less things in, it should run EXACTLY 100% like the examples. C language ONLY. And please dont reply if you cant run all the examples given. We know the tr command allows you to replace or translate characters in of a stream. It takes in two arguments - a set of characters to be replaced and a set of replacement characters. The full functionality...
Could someone please help me with this C language code I'm confused as to why i'm getting an error every time I run it on command line if some could please help me as soon as possible. #include <stdio.h> #include <stdlib.h> int main() { char *ptr_two = (char *)malloc(sizeof(char)*50); printf("%p\n", ptr_two); ptr_two = "A constant string in C"; printf("%p\n", ptr_two); printf("%s\n", ptr_two); free(ptr_two); return 0; }
