A shell for fast switching directories under UNIX operating systems

If your directory level is very deep, this shell will be very convenient to switch directly to the destination directory, such as

Current directory/usr/home, and directory Desdir in/usr/home/app/local/opp/william/desdir

Direct penetration

$ CD Desdir, you can switch directly from the current directory/use/home to/usr/home/app/local/opp/william/desdir

Configure. Profile, add two lines

. ./bin/chdir

Alias cd= ' ChDir '

File:chdir

# Auto Find your directory

# Writer:william 2006 Beijing

# Add the following two line in $HOME/.profile

# . ./bin/chdir

# alias cd= ' ChDir '
