macos – 在OS X上的Terminal.app中打开BASH shell时,如何设置PA

第一个bash源/ etc / profile执行以下代码：

if [ -x /usr/libexec/path_helper ]; then
    eval `/usr/libexec/path_helper -s`
    # The above line is the secret sauce,so to say...
    # First is adds default PATH values from the file /etc/paths
    # Then all files in the /etc/paths.d/ directory are read and directories listed
    # in each file (one per line) are appended to PATH
fi

if [ "${BASH-no}" != "no" ]; then
    [ -r /etc/bashrc ] && . /etc/bashrc
fi

下一个bash查找?/ .bash_profile,?/ .bash_login和?/ .profile.

列出这些步骤,PATH构建如下：

>文件/ etc / paths中的目录被添加到PATH中>目录/etc/paths.d/中的文件中列出的目录将附加到PATH – 注意,这些目录是附加的而不是前置的.>各种PATH = {DIR_2_ADD}：我的?/ .bash_profile和?/ .bashrc文件中的“${PATH}”语句前置PATH
