The `cd` program

cd changes the current working directory to a given directory, then executes a program.

Interface

     cd dir prog...

cd performs a chdir() system call on dir, then execs into prog....

cd is a standard shell builtin. Be careful if you want to use the cd command outside of an execline script
When execline has been configured with the --enable-pedantic-posix option, the cd binary is actually a symbolic link to the posix-cd binary.
