## README

调用 CS_PATH
in linux

login from tty(虚拟终端)
/bin/login will use ENV_PATH in /etc/login.defs file
(rocky not setting default is /usr/bin the same as getconf PATH)
and then /etc/profile
fish will not read ~/.profile,but bash do

getconf PATH
/bin:/usr/bin

linux ssh login
/etc/ssh/sshd_config
This sshd was compiled with PATH=/usr/local/bin:/usr/bin:/bin:/usr/games

as login shell(不继承其他 shell)
read /etc/profile
continue add some path in
/usr/share/fish/vendor_conf.d/00debian-profile.fish

not default login shell(继承其他 shell read from /etc/profile and ~/.profile)

not default login shell
terminal app read from GUI(systemctl --user show-environment)
kitty.conf add env PATH
env PATH=${PATH}:/usr/local/bin:/opt/homebrew/bin:${HOME}/miniforge3/bin
pass to fish

调用 CS_PATH
in macos
getconf -a | grep PATH
/usr/bin:/bin:/usr/sbin:/sbin

macos ssh login
/etc/ssh/sshd_config
This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin

as login shell(不继承其他 shell)
set path from
/etc/paths and /etc/paths/\*
getconf PATH
/usr/bin:/bin:/usr/sbin:/sbin

not default login shell
kitty(kitty getconf PATH /usr/bin:/bin:/usr/sbin:/sbin)
kitty.conf
kitty 一定传递 env 过去,因为要添加/Applications/kitty.app/Contents/MacOS kitty bin 目录
kitty 传递过去的 PATH 为/Applications/kitty.app/Contents/MacOS:/usr/bin:/bin:/usr/sbin:/sbin
后面部分是getconf PATH
env PATH=${PATH}:/usr/local/bin:/opt/homebrew/bin:${HOME}/miniforge3/bin

首先继承父进程(kitty)的PATH环境变量
如果父进程没有设置PATH，则使用系统配置的PATH（通过confstr(\_CS_PATH)获取）
如果系统配置不可用，则使用编译时定义的默认路径（${PREFIX}/bin:/usr/bin:/bin）
