The why of it:
When you execute a script it inherits the environment of the shell, and runs.
It does not affect the environment of the shell.
You can change this by using "." or 'source'. If you typed:
$ . go-bin
(assuming go-bin contains "cd /usr/local/bin"), your directory would change.
You can combine this with an alias. Name your script "chdir-bin", then in your
.bashrc put:
alias go-bin=". $HOME/scripts/chdir-bin" # Or wherever you keep it.
Then you just type "go-bin" at the shell, and bingo! You can also have these
scripts accept parameters to give you greater flexibility.
