How to permanently set $PATH on Linux/Unix? [closed]

Answer 1

Add to /etc/profile.d folder script [name_of_script].sh with line: export PATH=$PATH:/dir. Every script within /etc/profile.d folder is automaticaly executed by /etc/profile on login.

Answer 2

Let's say you're running MacOS and you have a binary you trust and would like to make available across your system but don't necessarily want the directory in which the binary is to be added to your PATH, you can opt to copy/move the binary to /usr/local/bin, which should already be in your PATH. This will make the binary executable like any other binary you may already have access to in your terminal.

Answer 3

You may set $PATH permanently in 2 ways.

1. To set path for particular user : You may need to make the entry in .bash_profile in home directory in the user.

   e.g in my case I will set java path in tomcat user profile

   [tomcat]$ echo "export PATH=$PATH:/path/to/dir" >> /home/tomcat/.bash_profile
   

2. To set common path for ALL system users, you may need to set path like this :

   [root~]# echo "export PATH=$PATH:/path/to/dir" >> /etc/profile
   

Answer 4

My answer is in reference to the setting-up of go-lang on Ubuntu linux/amd64.I have faced the same trouble of setting the path of environment variables (GOPATH and GOBIN), losing it on terminal exit and rebuilding it using the source <file_name> every time.The mistake was to put the path (GOPATH and GOBIN) in ~/.bash_profile folder. After wasting a few good hours, I found that the solution was to put GOPATH and GOBIN in ~/.bash_rc file in the manner:

export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOPATH:$GOBIN

and doing so, the go installation worked fine and there were no path losses.

EDIT 1: The reason with which this issue can be related is that settings for non-login shells like your ubuntu terminal or gnome-terminal where we run the go code are taken from ~./bash_rc file and the settings for login shells are taken from ~/.bash_profile file, and from ~/.profile file if ~/.bash_profile file is unreachable.

Answer 5

You can add that line to your console config file (e.g. .bashrc) , or to .profile

Answer 6

One way to add permanent path, which worked for me, is:

cd /etc/profile.d
touch custom.sh
vi custom.sh 
export PATH=$PATH:/path according to your setting/

Restart your computer and here we go; path will be there permanently.
