【简记】恢复误删的/etc/profile,以Debian为例
解决方法:拷贝或创建/etc/profile,修改权限与所属,保证操作系统正常。
Debian10系统 /etc/profile 默认内容为:
# /etc/profile: system-wide .profile file for the Bourne shell (sh(1)) # and Bourne compatible shells (bash(1), ksh(1), ash(1), ...). if [ "`id -u`" -eq 0 ]; then PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" else PATH="/usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games" fi export PATH if [ "${PS1-}" ]; then if [ "${BASH-}" ] && [ "$BASH" != "/bin/sh" ]; then # The file bash.bashrc already sets the default PS1. # PS1='\h:\w\$ ' if [ -f /etc/bash.bashrc ]; then . /etc/bash.bashrc fi else if [ "`id -u`" -eq 0 ]; then PS1='# ' else PS1='$ ' fi fi fi if [ -d /etc/profile.d ]; then for i in /etc/profile.d/*.sh; do if [ -r $i ]; then . $i fi done unset i fi
保存退出,修改权限
sudo chmod 644 /etc/profile
修改所属用户
sudo chown root:root /etc/profile
logout并重新登录
