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
【简记】恢复误删的/etc/profile,以Debian为例
