# 编辑sudoers vim /etc/sudoers # 在 root ALL=(ALL:ALL) ALL 后追加新行,如下图 u ALL=(ALL:ALL) ALL
# 恢复只读权限 chmod u-w /etc/sudoers
# 给新目录添加读写权限 chown u:u -R /home/u
# 切换到新用户 su u
从此刻开始,以非root用户编译lede

The following information has been given:
China Beijing Time
Therefore TZ='Asia/Shanghai' will be used. Selected time is now: Fri May 6 08:49:39 CST 2022. Universal Time is now: Fri May 6 00:49:39 UTC 2022. Is the above information OK? 1) Yes 2) No #? yes Please enter a number in range. #? 1
You can make this change permanent for yourself by appending the line TZ='Asia/Shanghai'; export TZ to the file '.profile' in your home directory; then log out and log in again.
Here is that TZ value again, this time on standard output so that you can use the /usr/bin/tzselect command in shell scripts: Asia/Shanghai
