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。

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?

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。

经过这么多的研究，我找到了一个简单的解决方案(我使用的是Elementary OS)，灵感来自Flutter - Step by Step Installation on Linux - Ubuntu。

2 .执行以下命令，以编辑方式打开“。bashrc”文件。(你 也可以使用vi或任何其他编辑器)。 ~$ sudo nano ~/.bashrc 在文件末尾添加以下行并保存。 导出路径= " [FLUTTER_SDK_PATH] /颤振/ bin: $路径” 例如: 导出路径= " / home / rageshl / dev /颤振/ bin:美元路径”

我相信这是在Ubuntu发行版中在Flutter中设置路径的永久解决方案。

可以通过两种方式永久设置$PATH。

设置指定用户的路径。 您可能需要在用户的主目录中的.bash_profile文件中创建条目。 例如，在我的情况下，我会在Tomcat用户配置文件*中设置java路径 echo "export PATH=$PATH:/ PATH /to/dir" >> /home/tomcat/.bash_profile . sh /home/tomcat/.bash_profile . sh 要为所有系统用户设置一个公共路径，可能需要这样设置: echo "export PATH=$PATH:/ PATH /to/dir" >> /etc/profile . sh /etc/profile . sh

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
