Question: How to run DIR command programmatically?
Answer: We can use the system( ) function to execute the DIR command along with its options. Following program shows how this can be achieved:// mydir.c main ( int argc, char *argv[ ] ) { char str[30] ; if ( argc < 2 ) exit ( 0 ) ; sprintf ( str, "dir %s %s", argv[1], argv[2] ) ; system ( str ) ; } If we run the executable file of this program at command prompt passing the command line arguments as follows: > mydir abc.c /s This will search the file 'abc.c' in the current directory. |
