Bash: executing commands from within a chroot and switch user
提问by dgrandes
Im writing a script that should do this...
我正在写一个应该这样做的脚本......
chroot /chroot_dir/ su -
./startup.sh (This should run within the su environment)
I have tried this approach:
我试过这种方法：
chroot /chroot_dir /bin/bash -c " su -; ./startup.sh"
This tries to execute the user switching and the script as a string command to bash...however what it does, is it "stops" after "su -"and doesnt execute the script. However, once I leave the "su -" environment, it does try to run startup.sh but of course, it cant find it.
这会尝试将用户切换和脚本作为字符串命令执行到 bash ……但是它的作用是在“su -”之后“停止 ”并且不执行脚本。但是，一旦我离开“su -”环境，它就会尝试运行 startup.sh 但当然找不到它。
Basically I need to nest the "startup.sh" to be run inside the "su -" environment...
基本上我需要嵌套“startup.sh”以在“su -”环境中运行......

basic option:
基本选项：
cat << EOF | chroot /chroot_dir
touch aaaaa
touch bbbbb
EOF
option with different shell (eg. if using bash but in chrooted enviroment it doesn't exists)
具有不同 shell 的选项（例如，如果使用 bash 但在 chrooted 环境中它不存在）
cat << EOF | chroot /chroot_dir /bin/sh
touch aaaaa
touch bbbbb
EOF
