I’m writing a shell and I want to use execv() and search for the right directory through the $PATH environment variable (Yes, I know I can use execvp() and just pass the name of the file to it).
What I’m thinking about doing is getting a string from getenv("PATH"), breaking it down to separate paths then trying each one. But I was wondering if there is an easier way to do it?
I guess the question is: how does execvp() search for the right path?
Thanks!
What you described is exactly how
execvp()searches the PATH. I don’t think there’s much point in reimplementing this yourself.
