Ubuntu – Add custom script to PATH

14.04bashcommand lineenvironment-variablesscripts

I know there are quite some answers about that, but still could not make my way around it. I read all this and tried to follow the example under System-wide environment variables (for my case of course), and also tried to do as the chosen answer here. But didn't work.

So, I have an executable shell script, located in ~/Developer/android-studio/bin and I want to make it so that when I am in the terminal (no matter were) and I write simply android-studio and the script to be executed (the IDE to start).

So, I tried with export AS=$PATH:~/Developer/android-studio/bin and also with

AS="~/Developer/android-studio/bin:${PATH}"
export AS

and then source .bashrc, but after both tries, when I write simply AS I get command not found. How can I make this work?

Another question – is it obligatory that I name the variable with capitals only and no dashes, because I want to name the variable something like android_studio instead of AS, i.e.?

It sounds like you want to do

export PATH="$PATH:~/Developer/android-studio/bin"

Then you'll be able to enter android-studio from anywhere. There's nothing magical about an environment variable named AS

If you want a shorthand, add a function to your .bashrc:

function as() { command android-studio "$@"; }

Ubuntu – Add android-studio/bin/ to PATH environmental variable

It looks like you edited this code snippet:

if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

which is included in ~/.profile by default.

The answer which lead you to do so is confusing IMNSHO.

I'd suggest that you change that code back to what it looked like before, and instead add a new line underneath it:

if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

PATH="$PATH:/usr/local/Android/android-studio/bin"

Then, next time you log in, PATH ought to be altered, whether $HOME/bin exists or not.

Ubuntu – Adding folders to your PATH environment variable

The steps are:

Open a terminal with the keyboard command Ctrl + Alt + T
Open ~/.bashrc in gedit:
```
gedit ~/.bashrc
```
Add this line to the file:
```
export PATH="[path_to_ndless]/ndless-sdk/toolchain/install/bin:[path_to_ndless]/ndless-sdk/bin:${PATH}"  
```
Here the [path_to_ndless] is simply the path to where you droped the ndless-sdk folder when you installed it. Remove that placeholder text and replace it with that path value. Say you placed that git repo in /home/georgek/ndless then your path to add into ~/.bashrc would be:
```
export PATH="/home/georgek/ndless-sdk/toolchain/install/bin:/home/georgek/ndless-sdk/bin:${PATH}"
```
Save the file and close gedit.
Now to get your environmental variables you just added to show in your currently opened terminal run the command:
```
 source ~/.bashrc
```

Please note several things:

This ~/ means /home/$USER, where $USER mean your username, mine being georgek.
So I could have also written /home/georgek/.bashrc
