我认为最优雅的方式是:

将此添加到~/。bashrc文件。( 执行如下命令: 中~ / . bashrc 在里面添加你的路径: 导出路径= $路径:/ bin / opt /节点 源~ / . bashrc

(Ubuntu)

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.

Wayland上的GNOME启动一个用户登录shell来获取环境。它有效地使用登录shell配置~/。简介~ /。<壳> _profile ~ /。<壳> _login文件。

登录Shell和非登录Shell的区别?

可以通过以下命令直接添加:

echo 'export PATH=$PATH:/new/directory' >> ~/.zshrc
source ~/.zshrc

Zues77的想法是正确的。操作人员没有说“我怎么才能破解这个?”OP想知道如何永久地附加到$PATH:

sudo nano /etc/profile

这是为所有东西设置的地方，也是为所有需要$PATH的东西更改它的最佳位置。

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

本地用户可在CentOS或redhat Linux (RHEL)上使用:

echo $"export PATH=\$PATH:$(pwd)" >> ~/.bash_profile

这将当前目录(或者您可以使用另一个目录)添加到PATH。这使它成为永久的，但它在下一次用户登录时生效。

如果你不想重新登录，那么你可以使用:

source ~/.bash_profile

这将重新加载#用户特定环境和启动程序。该注释出现在.bash_profile文件中。
