Shell 提权 ¶

#Linux #Shell
请求 ROOT 权限以运行脚本

#!/bin/bash

[ $UID -ne 0 ] && {
  exec sudo "$0" "$@"
  exit $?
}

WorkDir=$(cd $(dirname $0);pwd)
pushd $WorkDir
systemctl reset-failed
systemd-run -p User=hsiaotien \
  -p Group=hsiaotien \
  -p NoNewPrivileges=yes \
  -p ProtectSystem=full \
  -p ReadOnlyPaths=/home/hsiaotien \
  -p ReadWritePaths=$WorkDir \
  -p ReadWritePaths=/home/hsiaotien/.config/copyparty \
  -u copyparty \
  .venv/bin/python $WorkDir/copyparty-sfx.py

关键点

• 用 exec 在当前环境中启动，同时执行完后退出，以免脚本被多次执行
