Linux tools: Quickly return to a level parent directory--BD

When we switch the parent directory on a Linux server, the CD is usually used. /.. /, there are several levels of directories to enter a few times ". /"If the directory is too deep to nest, it will be a bit of a dizzy dish ... Therefore, this introduction of the tool, you can quickly return to the specified parent directory.

1. Installation

# Download sudo wget --no-check-certificate-o/usr/bin/bd https://RAW.GITHUB.COM/VIGNESHWARANR/BD/MASTER/BD  # Modify Permissions sudochmod +rx/usr/bin/bd# Add alias, ignore case Echo'  Alias bd= ". Bd-si "' >> ~/~/.BASHRC

2. Use

# Assuming the current path is as follows /home/hadoop/medis/data/program/books/learn/scala/test# Use the following command to tune to /home/hadoop/ medis/data/program/Books directory BD Books

You can also use ' BD < start several letters > ' to move directly to the directory that starts with that letter. Note: When the hierarchy has the same name directory,BD will move to the nearest directory instead of the parent directory that first appears :

# Assuming the current directory /home/hadoop/medis/data/program/books/learn/scala/test/extra/scala/play/structure# Jump to /home/hadoop/Medis in BD me# with the same name as the Scala directory, current path /home/hadoop/medis/data/program/books/learn/scala/test/ extra/scala/play/structurebd Scala/home/hadoop/medis/data/program/books/learn/scala/test/extra/scala/

Finally, in conjunction with other commands, note that the BD command in the command line quotes is used only to list the switched directories and does not perform a switchover, so the current path does not change

#当前路径/home/hadoop/medis/data/program/books/learn/scala/test/extra/echo  ' BD Lea ' /home/hadoop/medis/data/program/books/learn/ls -4 drwxrwxr  34096: Scala
