System Commands Output

nasir_qau · 03-21-2002, 02:10 PM

I want to save the output of system command in the memory location.For example the following command will save the output in the file /tmp/lsfile.txt.

system("ls -al > /tmp/lsfile.txt");

Rather than saving it in file is it possible to save it in some string variable or any other data structure?Does any on know?

There probly is, but if you want a temporary solution just load the file.

Yes there is. try this:

Code:

FILE *fp;

fp=popen("ls -al", "r");

/* read from "fp" using f***-functions */

pclose(fp);
