你也可以永久地设置它，编辑这些文件之一:

/etc/profile(针对所有用户)

~ /。Bash_profile(用于当前用户)

~ /。Bash_login(用于当前用户)

~ /。配置文件(适用于当前用户)

也可以使用/etc/environment设置永久的PATH环境变量，但不支持变量展开。

提取自:Linux: Añadir ruta al PATH

我昨天在寻找一种方法将包含我自己的脚本的文件夹添加到PATH时偶然发现了这个问题-并且惊讶地发现我自己的~/。配置文件(在Linux Mint 18.1上)已经包含这个:

# set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
    PATH="$HOME/bin:$PATH"
fi

因此，我所要做的就是创建文件夹~/bin并将脚本放在那里。

修改“/etc/profile”文件: vi / etc / profile 按“I”键进入编辑模式，将光标移至文件末尾。额外的条目: 导出路径= $路径:/道路/ / dir; 按“Esc”键退出编辑模式，并按“:wq”保存文件。 使配置有效 源/ etc / profile 解释: 配置文件适用于所有用户。如果希望它仅对活动用户有效，请更改“。bashrc”(文件。

假设你运行的是macOS。您有一个信任的二进制文件，并希望在整个系统中可用，但不一定希望将二进制文件所在的目录添加到PATH中。

您可以选择复制/移动二进制文件到/usr/local/bin，它应该已经在您的PATH中。这将使二进制可执行文件与您在终端中已经访问的任何其他二进制文件一样。

有很多种方法。实际的解决方案取决于目的。

变量值通常存储在赋值列表中或在系统或用户会话开始时运行的shell脚本中。对于shell脚本，您必须使用特定的shell语法和导出或设置命令。

系统范围

/etc/environment List of unique assignments. Allows references. Perfect for adding system-wide directories like /usr/local/something/bin to PATH variable or defining JAVA_HOME. Used by PAM and systemd. /etc/environment.d/*.conf List of unique assignments. Allows references. Perfect for adding system-wide directories like /usr/local/something/bin to PATH variable or defining JAVA_HOME. The configuration can be split into multiple files, usually one per each tool (Java, Go, and Node.js). Used by systemd that by design do not pass those values to user login shells. /etc/xprofile Shell script executed while starting X Window System session. This is run for every user that logs into X Window System. It is a good choice for PATH entries that are valid for every user like /usr/local/something/bin. The file is included by other script so use POSIX shell syntax not the syntax of your user shell. /etc/profile and /etc/profile.d/* Shell script. This is a good choice for shell-only systems. Those files are read only by shells in login mode. /etc/<shell>.<shell>rc. Shell script. This is a poor choice because it is single shell specific. Used in non-login mode.

用户会话

~/.pam_environment. List of unique assignments, no references allowed. Loaded by PAM at the start of every user session irrelevant if it is an X Window System session or shell. You cannot reference other variables including HOME or PATH so it has limited use. Used by PAM. ~/.xprofile Shell script. This is executed when the user logs into X Window System system. The variables defined here are visible to every X application. Perfect choice for extending PATH with values such as ~/bin or ~/go/bin or defining user specific GOPATH or NPM_HOME. The file is included by other script so use POSIX shell syntax not the syntax of your user shell. Your graphical text editor or IDE started by shortcut will see those values. ~/.profile, ~/.<shell>_profile, ~/.<shell>_login Shell script. It will be visible only for programs started from terminal or terminal emulator. It is a good choice for shell-only systems. Used by shells in login mode. ~/.<shell>rc. Shell script. This is a poor choice because it is single shell specific. Used by shells in non-login mode.

登录Shell和非登录Shell的区别?

最简单的方法是，

PATH="<directory you want to include>:$PATH"

在主目录下的。bashrc文件中。

即使你关闭终端或重启电脑，它也不会被重置。它是永久性的。
