How To Navigate Inside A Directory/Folder In Linux Without CD Command?
As everybody know that we can’t navigate inside a directory in Linux without CD command.
Yes that’s true but we have the Linux built-in command called shopt that help us to solve this issue.
shopt is a shell builtin command to set and unset various bash shell options, which is installed so, we no need to install it again.
Yes we can navigate inside a directory without CD command after enabling this option.
We will show you, how to do this in this article. This is a small tweak but it’s very useful for newbies who all are moving from Windows to Linux.
This is not useful for Linux administrator because we won’t navigate to the directory without CD command, as we had a good practices on this.
If you are trying to navigate a directory/folder in Linux without cd command, you will be getting the following error message. This is common in Linux.
$ Documents/
bash: Documents/: Is a directory
To achieve this, we need to append the following values in a user .bashrc file.
What Is the .bashrc File?
The “.bashrc” file is a shell script which is run every time a user opens a new shell in interactive mode.
You can add any command in that file that you want to type at the command prompt.
The .bashrc file itself contains a series of configurations for the terminal session. This includes setting up or enabling: colouring, completion, the shell history, command aliases and more.
$ vi ~/.bashrc
shopt -s autocd
Run the following command to make the changes to take effect.
$ source ~/.bashrc
We have done all the configuration. Simple do the testing on this to confirm whether this working or not.
$ Documents/
cd -- Documents/
$ daygeek/
cd -- daygeek/
$ /home/daygeek/Documents/daygeek
cd -- /home/daygeek/Documents/daygeek
$ pwd
/home/daygeek/Documents/daygeek
Yes, it’s working fine as expected.
However, it’s working fine in fish shell without making any changes in the .bashrc file.
If you would like to perform this action for temporarily then use the following commands (set/unset). This will go away when you reboot the system.
# shopt -s autocd
# shopt | grep autocd
autocd on
# shopt -u autocd
# shopt | grep autocd
autocd off
shopt command is offering so many other options and if you want to verify those, run the following command.
$ shopt

assoc_expand_once off
cdable_vars off

I had found few other utilities, that are help us to navigate a directory faster in Linux compared with cd command.
Those are pushd, popd, up shell script and bd utility. We will cover these topics in the upcoming articles.
