Now we know that we have to add two functions: Usage() and Search_in_File(). If everything went alright the program will return 0. The results are captured to do some basic error-handling in the if statement that follows. The actual work is done in the next statement where we call a second function called Search_in_File that uses our command-line input. The system() function can execute a system specific command. With the system(“cls”) function on windows and system(“clear”) function on Unix/Linux we can clear our screen, so we can display the results on a fresh screen.

Probably the file types still have to be set up correctly in Advanced Options of Indexing Options'. In Windows Explorer, go to menu Tools/Folder options and select 'Always search file names and contents'. #Search files for text string windows 7 windows 7you may not have the appropriate permissions to access the item. Windows 7 still has the ability to search for strings inside files everywhere (and not in indexed locations). ![]() (Note: that the first command-line parameter is the program itself.) When using the search bar on the start menu, after inputting a string and clicking 'see more results' I get the following popup message: Search:querysearch string Windows cannot access the specified device, path, or file. ![]() We just say if the command-line parameters are smaller or larger than three, display our usage function and exit the program. We also want to make sure that we get a proper usage message, if the command-line options are not inputted correctly. This why we use int main(int argc, char *argv). Result = Search_in_File(argv, argv) īecause we want to write a program that can that can be used over and over, we need to make sure that all the variables we need, such as filename and the search-string, can be inputted at the command-line.
