c/c++ running a shell script?

thermalpants · 05-12-2002, 06:48 AM

Hi,
I am trying to write a small c/c++ program as a wrapper for a bash script. I need the wrapper to take some input args, call the bash script with the supplied args and then return the output of the bash script.

As far as I can see system() will call the script ok, but it will only return an int , not the actual output of the script, unless I've got that wrong.

Can anyone help me out here?

thanks

man fork
man pipe
man wait

HTH,

Easy way will be write output to file from bash and then read that file from c++ program.

Yeah, its looking that way at this point. unfortunately my knowledge of c doesn't stretch to forking and piping and I am under time pressure right now.

thanks for the suggestions.
