我正在 bash_profile 中做一些事情，例如：

$PATHcan have several paths separated by a colon (:). E.g.:
$PATH可以有多个路径以冒号 ( :)分隔。例如：
export PATH=/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/myuser/bin

Set the $PATHenvironment variable to include the directory where you installed the bin directory with shell scripts and two consecutive export entries as in example.
将$PATH环境变量设置为包含您安装 bin 目录的目录，其中包含 shell 脚本和两个连续的导出条目，如示例中所示。
Example:
示例：
export ANT_HOME=/path/to/ant/dir
export PATH=${PATH}:${ANT_HOME}/bin:${JAVA_HOME}/bin
To make them permanent entries update the bash_profile file.
要使它们成为永久条目，请更新 bash_profile 文件。

One way to add multiple executables to the $PATH variable is:
将多个可执行文件添加到 $PATH 变量的一种方法是：
export PATH=/path/to/executable1:\
/path/to/executable2:\
/path/to/executable3:\
/path/to/executable4
If a $PATHalready exists in .bash_profile, and you want them to take precedence over executables(like java and php), you can do:
如果 a$PATH已存在于 中.bash_profile，并且您希望它们优先于可执行文件（如 java 和 php），您可以执行以下操作：
export PATH=$PATH:/path/to/executable1:\
/path/to/executable2:\
/path/to/executable3:\
/path/to/executable4
If the path to any executable contains whitespaces, add the part / ... executableXin quotes.
如果任何可执行文件的路径包含空格，请/ ... executableX在引号中添加该部分。
Once you're done making changes in your bash_profile, source the file in a terminal session so that changes are effective immediately:
完成更改后bash_profile，在终端会话中获取文件，以便更改立即生效：
source .bash_profile
