UP Shell Script – Quickly Navigate To A Specific Parent Directory In Linux
|
||
======
|
||
|
||
Recently we had written an article about **[bd command][1]** , which help us to **[quickly go back to the specific parent directory][1]**.
|
||
|
||
Even, the [up shell script][2] allow us to perform the same but has different approach so, we would like to explore it.
|
||
|
||
This will allow us to quickly navigate to a specific parent directory with mentioning the directory name.
|
||
|
||
Instead we can give the directory number. I mean to say that number of times you’d have to go back.
|
||
|
||
Stop typing `cd ../../..` endlessly and navigate easily to a specific parent directory by using up shell script.
|
||
|
||
It support tab completion so, it’s become more convenient.
|
||
|
||
The `up.sh` registers the up function and some completion functions via your `.bashrc` or `.zshrc` file.
|
||
|
||
It was completely written using shell script and it’s support zsh and fish shell as well.
|
||
|
||
We had written an article about **[autocd][3]**. It’s a builtin shell variable that helps us to **[navigate to inside a directory without cd command][3]**.
|
||
|
||
### How To Install up Linux?
|
||
|
||
It’s not based on the distribution and you have to install it based on your shell.
|
||
|
||
Simple run the following command to enable up script on `bash` shell.
|
||
|
||
```
|
||
$ curl --create-dirs -o ~/.config/up/up.sh https://raw.githubusercontent.com/shannonmoeller/up/master/up.sh
|
||
|
||
$ echo 'source ~/.config/up/up.sh' >> ~/.bashrc
|
||
```
|
||
|
||
Run the following command to take the changes to effect.
|
||
|
||
```
|
||
$ source ~/.bashrc
|
||
```
|
||
|
||
Simple run the following command to enable up script on `zsh` shell.
|
||
|
||
```
|
||
$ curl --create-dirs -o ~/.config/up/up.sh https://raw.githubusercontent.com/shannonmoeller/up/master/up.sh
|
||
|
||
$ echo 'source ~/.config/up/up.sh' >> ~/.zshrc
|
||
```
|
||
|
||
Run the following command to take the changes to effect.
|
||
|
||
```
|
||
$ source ~/.zshrc
|
||
```
|
||
|
||
Simple run the following command to enable up script on `fish` shell.
|
||
|
||
```
|
||
$ curl --create-dirs -o ~/.config/up/up.fish https://raw.githubusercontent.com/shannonmoeller/up/master/up.fish
|
||
|
||
$ source ~/.config/up/up.fish
|
||
```
|
||
|
||
### How To Use This In Linux?
|
||
|
||
We have successfully installed and configured the up script on system. It’s time to test it.
|
||
|
||
I’m going to take the below directory path for this testing.
|
||
|
||
Run the `pwd` command or `dirs` command to know your current location.
|
||
|
||
```
|
||
daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256/apps$ pwd
|
||
or
|
||
daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256/apps$ dirs
|
||
|
||
/usr/share/icons/Adwaita/256x256/apps
|
||
```
|
||
|
||
How to up one level? Quickly go back to one directory. I’m currently in `/usr/share/icons/Adwaita/256x256/apps` and if i want to go one directory up `256x256` directory quickly then simple type the following command.
|
||
|
||
```
|
||
daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256/apps$ up
|
||
|
||
daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256$ pwd
|
||
/usr/share/icons/Adwaita/256x256
|
||
```
|
||
|
||
How to up multiple levels? Quickly go back to multiple directory. I’m currently in `/usr/share/icons/Adwaita/256x256/apps` and if i want to go to `share` directory quickly then simple type the following command.
|
||
|
||
```
|
||
daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256/apps$ up 4
|
||
|
||
daygeek@Ubuntu18:/usr/share$ pwd
|
||
/usr/share
|
||
```
|
||
|
||
How to up by full name? Quickly go back to the given directory instead of number.
|
||
|
||
```
|
||
daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256/apps$ up icons
|
||
|
||
daygeek@Ubuntu18:/usr/share/icons$ pwd
|
||
/usr/share/icons
|
||
```
|
||
|
||
How to up by partial name? Quickly go back to the given directory instead of number.
|
||
|
||
```
|
||
daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256/apps$ up Ad
|
||
|
||
daygeek@Ubuntu18:/usr/share/icons/Adwaita$ pwd
|
||
/usr/share/icons/Adwaita
|
||
```
|
||
|
||
As i told in the beginning of the article, it supports tab completion.
|
||
|
||
```
|
||
daygeek@Ubuntu18:/usr/share/icons/Adwaita/256x256/apps$ up
|
||
256x256/ Adwaita/ icons/ share/ usr/
|
||
```
|
||
|
||
This tutorial allows you to quickly go back to a specific parent directory but there is no option to move forward quickly.
|
||
|
||
We have another solution for this, will come up with new solution shortly. Please stay tune with us.
