Shells execute in their own instance of bash (or whatever) - a
subshell. The way to do this is with an alias or function, depending
on your needs (aliases don't except parameters, functions do), so
here's the function for "mdcd":
$ mdcd() {
# additional checks here, per original post
mkdir $1
cd $1
}
Alternatively, you can force a script to run in the current shell by sourcing it
$ . {scriptname}
Note the "." between the prompt and script (you can also use the more
literal "source"):
$ source {scriptname}
Another option, just for completeness, would be to alias sourcing a
script, e.g.:
$ alias mdcd='. {path to script}'
