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][1] 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
|
||
autocd on
|

|
||
|
||
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.
