path.md

The PATH is an important concept when working on the command line. It's a list of directories that tell your operating system where to look for programs, so that you can just write script instead of /home/me/bin/script or C:\Users\Me\bin\script. But different operating systems have different ways to add a new directory to it:

Windows

1. The first step depends which version of Windows you're using:

• If you're using Windows 8 or 10, press the Windows key, then search for and select "System (Control Panel)".
• If you're using Windows 7, right click the "Computer" icon on the desktop and click "Properties".

2. Click "Advanced system settings".
3. Click "Environment Variables".
4. Under "System Variables", find the PATH variable, select it, and click "Edit". If there is no PATH variable, click "New".
5. Add your directory to the beginning of the variable value followed by ; (a semicolon). For example, if the value was C:\Windows\System32, change it to C:\Users\Me\bin;C:\Windows\System32.
6. Click "OK".
7. Restart your terminal.

Mac OS X

1. Open the .bash_profile file in your home directory (for example, /Users/your-user-name/.bash_profile) in a text editor.
2. Add export PATH="your-dir:$PATH" to the last line of the file, where your-dir is the directory you want to add.
3. Save the .bash_profile file.
4. Restart your terminal.

Linux

1. Open the .bashrc file in your home directory (for example, /home/your-user-name/.bashrc) in a text editor.
2. Add export PATH="your-dir:$PATH" to the last line of the file, where your-dir is the directory you want to add.
3. Save the .bashrc file.
4. Restart your terminal.

Oh, nice. Thankyou :)

I would just like to say that you should consider using export PATH="$PATH:your-dir" instead. This will append the new path to the variable. Adding the absolute path to the beginning of the file will make the system search that directory first every time. This is not recommended as it can cause problems with system programs and it adds unnecessary delay.

am facing this error when trying to add a path

use nano instead of gedit, gedit has issues when trying to run from tty

small correction use PATH instead of $PATH in the first parameter after export:
export PATH="$HOME/appl/code/leap-demo-app:$PATH"

think about why using one instead of the other.

• assign
• expand
  that is why, they are different.

I tried following these instructions on my Mac, edited my .bash_profile and appended the line:
export PATH="/Users/.../dart-sass:$PATH" (where ... is the rest of the absolute path of the dart-sass directory)
However, when I run sass --version in terminal, I get the error -bash: sass: command not found.

Am I doing anything wrong? It is very frustrating and confusing.

Edit: Problem was fixed when I tried the line: export PATH="$PATH:/Users/.../dart-sass". I am still confused as to how this fixed the problem though.

for me: on .bashrc
I just added
PATH=$PATH:/directory

You do not have to restart terminal. You can use source command
source ~/.bashrc

@kjcaputa
Thanks!, source command is awesome!
example

Thank you, dude!!
in my case (Ubuntu Desktop 20.10) I just ran the following command in the Terminal PATH="/directory:$PATH"

For those using Z-Shell (zsh) don't forget it's .zshrc instead of .bash_profile

thanks

This worked for me using zsh, thanks!

why do we need to append ":$PATH" at the end?

@davidliu611 This is a simple concatenation of the string in the bash scripting language. You allow the original PATH string to be concatenating with the dir that you specified. check this out using
echo $PATH (in terminal)
you will see that your dir has been added at the beginning of the PATH.
PATH is the location where the system will look for other apps, scripts, env. .etc.

worked great, thank you so much

It is not working for me. I am using kali linux. Do you know what is the problem?

Life saver 👍

Excellent work. Thank you for this upload.

I love you, I forget that and spent 3 hours trying all solutions, till I read your comment.
