Adding linux commands to C programs

Hi Guys,

I'm currently working on a program which sorts a file and returns all the words in a file together with their frequencies, I'm thinking of using linux commands like "wc" "sort" and others which I know can do the Job I'm thinking of a way of integrating these commands directly into the c program including 'probably' the necessary header files and libraries, without actually calling the commands with argv. Could some one please help me out here?

Thanks,
Nyah

I'm thinking probably of using 'getopt' and optarg here, but not sure how.

look at the exec family of functions, and popen. popen is probably the best choice for what you want to do.
