16.5. Wyznaczanie wartości $CDPATH
Problem
Chcemy ułatwić sobie przechodzenie między kilkoma katalogami zapisanymi w różnych miejscach systemu plików.
Rozwiązanie
Należy wyznaczyć odpowiednią wartość zmiennej $CDPATH. Nazwy często wykorzystywanych katalogów zazwyczaj nie powtarzają się, więc jako przykład możemy rozważyć pracę z kilkoma katalogami skryptów startowych.
/home/marek$ cd rc3.d -bash: cd: rc3.d: Nie ma takiego pliku ani katalogu /home/marek$ export CDPATH='.:/etc' /home/marek$ cd rc3.d /etc/rc3.d /etc/rc3.d$ cd rc5.d /etc/rc5.d /etc/rc5.d$ /etc/rc5.d$ cd games -bash: cd: games: Nie ma takiego pliku ani katalogu /etc/rc5.d$ export CDPATH='.:/etc:/usr' /etc/rc5.d$ cd games /usr/games /usr/games$
