If you ask to override your chdir() built-in function, then your +PWD environment variable will be kept up to date. (See +L<perlsub/Overriding builtin functions>.) + +The fastgetcwd() function looks the same as getcwd(), but runs faster. +It's also more dangerous because you might conceivably chdir() out of a +directory that you can't chdir() back into. |
