How to add multiple folders to your PATH ?

[Ghost_Mazal]

Lo Guys , I want to add some folders to my PATH variable in my ~/.bashrc file. It was quite easy by adding this :


PATH=$PATH:/home/backupuser
export PATH

But what must I add if I want to add 3 or 4 other folders as well ?

Thanx

You can abbreviate the command into a single one, as follows.

export PATH=${PATH}:/first/path:/second/path:/third/path

Doesn't work.

When I test with echo $PATH it still only shows just the first folder

[Paddy Landau]

Are you writing the PATH command in the same terminal session as you are using it? If you perform the PATH command, then close the terminal, the change is lost.

If you are using the same session, please post your exact command (cut-and-paste), followed by your echo command showing the results.

It is placed in my ~/.bashrc file and bashrc reloaded with


source .bashrc

Here is the extract from my .bashrc file


export PATH=${PATH}:/home/backupuser:/home/wikusv:/home/barrydk

I have read and write permissions to all those folders.

After I reloaded my .bashrc with


source .bashrc

I test it with


echo $PATH

And it only shows all the system defaults (the bin folders) and the very first folder there in the list. (/home/backupuser)
The other two are not shown at all.

I find this puzzling. I started a terminal session; copied your line into my .bashrc; ran source .bashrc; and it worked perfectly for me.



In your .bashrc file, immediately after your export command, enter the following command:

echo 'Here I am'
Save the file.
Close your terminal.
Open a new terminal. Do you see "Here I am"?

Ok hang on. I completely logged out now and logged back in. Now it shows correctly. So it's the command


source .bashrc

That didn't load the changes correcly :confused:

Strange

[Ghost_Mazal]

That echo of yours works as well.

Anyway , your command in bashrc works thanx a lot.
It was just that I had to log out and log in again and not only run
the source command. ;)

[Paddy Landau]

It's hard to say in retrospect, but you have it now.

Usually, when I change .bashrc, I close the existing terminal and open a new one.

You shouldn't have had to log out and back in; I wonder if there was some error from a previous invocation?

Similar problem. I adjusted the system path on my box to include the Android SDK stuff. This is located on my machine in /opt/google/sdk, with the specific binaries in /opt/google/sdk/platform-tools/.

I edited the master path file, /etc/environment to reflect this:


george@diode:~$ cat /etc/environment
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/google/sdk/platform-tools"


This is then reflected after a reboot:


george@diode:~$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/google/sdk/platform-tools

Running a program, such as the Android Debugger Bridge (/opt/google/sdk/platform-tools/adb) as a normal user (here, "george") works fine


george@diode:~$ adb
Android Debug Bridge version 1.0.26
(... output chopped off ...)


However, this needs to be run as root, and this is where I get problems...


george@diode:~$ sudo adb
[sudo] password for george: <super_secret_password>
sudo: adb: command not found


sudo seems to see the right path, but never finds the application.


george@diode:~$ sudo echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/opt/google/sdk/platform-tools


Can anyone help with this? It's not an issue, as I can sudo -s and set the path up manually, but every time I close the terminal (dropping sudo -s out), I obviously loose it. Driving me mad!

Cheers all

Did you reload:


source /etc/environment
