Does anyone know how to catch the output (I think its stdout) from execvp instead of the system printing it (in c on linux) in the terminal?

execvpreplaces the current running process in memory. There’s no “catching” the output.I suspect you’re trying to run an external process from an existing process, and parse its output. For that you need to use
popen()which does afork()then anexec(), returning aFILE *to read (which will be thestdoutof the process you just ran).
