All right I am currently writing a c function in unix... and is trying to create a child shell to execute various command along with its arguments such as

ls

cd "directory name"

yeah it is a bit redundant, but I am just beginning and this seemed like a good exercise


but for some reason every command work except for my

cd command....

no matter what I remain in the root directory instead of going to the destrination directory....

I am using execvp if I successfully create a fork... and have the parent pid wait until the child pid has finished it functions before proceeding....

I am guessing so far now is that whenever I close the child directory, any non-permanent (such as mkdir) are ignored as I close that child thread and open a new one....

again I am only guessing at this... is there anyone who might see me through this.... Thanks....

You might consider looking at your environmental variable
and how they are passed to the child process. For example,
the child process may read the environmental variables
during the fork/exec process. If they do and you have
not set them correctly, the old environmental variables
may be used. This could be causing your grief
