$ mv ~/some/complicated/long/path

Then, a “cd M-.” becomes:

$ cd ~/some/complicated/long/path

Tada, lots of typing saved, which is why in the end of the day we use the shell — to be faster.

There is maybe simpler way how to hide Terminal.app, use handy DockLess utility!

cd() {
[ $EUID -ne 0 ] &*)
. .cdoutrc
;;
esac
}
}
case $# in
0)
builtin cd
;;
1)
builtin cd “$@”
;;
2)
builtin cd “${PWD%${1}*}${2}${PWD#*${1}}”
;;
*)
builtin cd “$@”
;;
esac
[ $? -eq 0 ] &*)
. .cdinrc
;;
esac
}
}
# restore $? to 0 for use with “cd xxx && yyy”
true
}
}
export -f cd

As an added bonus if you invoke “cd” with two arguments the first string in the current directory will be replaced by the second argument and the resulting directory will be switched to. If for example I’m in a directoy called “/Users/mg/version1″ and I type “cd 1 2″ I will find myself in the directory “/Users/mg/version2″.

Note that any .cdinrc and .cdoutrc files must be executable, they must be in a sub-directory of your $HOME, and you cannot be root (EUID 0). Of course you can change all that.
