And because any programs you run from a bash prompt are called by bash, the new path is in force for anything you run from the bash prompt.The bottom line is that to add a new directory to the path, you must append or prepend the directory to the $PATH environment variable within a script included in the shell, and you must export the I can't speak for other distributions, but Ubuntu has a file, /etc/environment, that is the default search path for all users.# see /usr/share/doc/bash/examples/startup-files for examples. #umask 022 # if running bash if [ -n "$BASH_VERSION" ]; then # include .bashrc if it exists if [ -f "$HOME/.bashrc" ]; then .$PATH is nothing but an environment variable on Linux, OS X, Unix-like operating systems, and Microsoft Windows.You can specify a set of directories where executable programs are located using $PATH.The $PATH variable is specified as a list of directory names separated by colon (:) characters.To print the current settings, open the Terminal and then type: The path_helper utility reads the contents of the files in the directories /etc/paths.d and /etc/manpaths.d and appends their contents to the PATH and MANPATH environment variables respectively.(The MANPATH environment variable will not be modified unless it is already set in the environment.)Files in these directories should contain one path element per line.
I simply would like to add an Environment variable to a Windows machine (desktop or server) and be able to use it without rebooting that machine. Changes to environment variables should take effect immediately, if you make the change via the main Properties dialog for the computer in question (go to My Computer | Properties | Advanced | Environment Variables).Say you have a production server which hosts a variety of apps and a new app needs a particular Environment variable to run. After the changes are saved, Explorer broadcasts a message to all windows to inform them of the change.You do not want to reboot it while users are connected to your other apps. I don't like the wait-until-a-good-time-to-reboot option. Any programs spawned via Explorer after this should get the updated environment, although already-running programs will not, unless they handle the setting change message.# ~/.profile: executed by the command interpreter for login shells.# This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login # exists. # the default umask is set in /etc/profile; for setting the umask # for ssh logins, install and configure the libpam-umask package.
