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.

my pleasure :)
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

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

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

Works on Command prompt. But not in Bash? can anyone help?.

it still says unknown command lvim

RapidEE is an outstanding alternative to the Windows built-in control panel dialog box for environment variable management and viewing, including the PATH variable, of course. For those who like text walls, read on! xP

BTW, thanks nex3. Cool tips!

TL;DR Version:

Although it's not necessary in the slightest, and for the standard non-hacker end-user probably smacks of overkill, if you are like me in meeting the following two criteria:

• A. Are forced to use Windows due to its popularity or your own masochistic tendencies; and furthermore
• B. Make use of environment variables (esp. PATH) fairly often, like most developers,

then you should find in RapidEE a beautiful tool to replace the tiny control panel dialog box. The native Windows method is fine for simple, "one-off" changes to PATH or a different variable, for a more comprehensive, "bird's eye" view of both system and user variables and the ability to add/delete or modify them—all quickly and easily, without the confusion the regular dialog can entail—the handy, small program called Rapid Environment Editor (or RapidEE) is more than sufficient. Although it's closed-source (afaik), it's free, up-to-date and even supports operations on variables via command-line arguments.

I'm fully aware there are other apps that fill the same need, many of them FOSS, but when I use Windows RapidEE has served me very well, and its features continue to save me many headaches from confusion, tedium and their ilk. Anyway, happy hacking, guys, and thanks again nex3!

i tried for lunarvim and its not working
export PATH="$PATH: ~/.local/bin/"

i tried for lunarvim and its not working export PATH="$PATH: ~/.local/bin/"

use this export PATH="your-dir:$PATH"

In my experience , used : export PATH=/.cargo/bin:/.local/bin:$PATH In file .bashrc appended last line
ps. DIST. ARCH

Still helpful. tks

for those using fish on macOS,

1. go to /Users/account-name/.config/fish

2. open config.fish and paste the following line inside the file

export PATH="/Users/account-name/.local/bin:$PATH"

Sometimes, I noticed modifying the .bashrc file doesn't work instead,
Adding the new PATH in .zshrc file (which is the default shell for MacOs) works for me.
add a new line in the file $HOME/.zshrc:

#for example
export PATH="your-bin-dir:$PATH"

then run
source $HOME/.zshrc

to reflesh the file

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

Thank you!! This worked for me too

for fish terminal users use this

fish_add_path export '/home/$USER/.local/bin' 

for fish terminal users use this

fish_add_path export '/home/$USER/.local/bin' 

Ok but how does this work? I'm not on my computer rn so I can't check, I am very new and have never seen a fish config file. Could you please explain how this works? Especially because I've seen the path to lunarvim in every other solution.

Create an alias and happy coding.
In ~/.config/fish/config.fish add:

alias lvim="~/.local/bin/lvim"

But, to use correctly export from fish use:

fish_add_path -m ~/.local/bin

Thank you. I'm new in linux and thats was driving me crazy.
