在第27行缺少一个 `fi` 关键字来结束第20行的 `if` 语句。同时，第24行的 `echo` 命令中，应该把逗号放在双引号内，否则会被视为两个参数。正确的脚本如下：

#!/bin/bash

users=$(cut -d: -f1 /etc/passwd)

for user in $users
do
    if [[ $(getent passwd $user | cut -d: -f3) -ge 1000 ]]
    then
        if [[ $(chage -l $user | grep "Password expires" | cut -d: -f2 | tr -d ' ') == "never" ]]
        then
            echo "$user: Password never expires"
        else
            expire_date=$(date -d "$(chage -l $user | grep "Password expires" | cut -d: -f2 | tr -d ' ')" +%s)
            current_date=$(date +%s)
            if [[ $expire_date -lt $current_date ]]
            then
                echo "$(hostname -I | awk '{print $1}'), $user: Password has expired"
            else
                echo "$user: Password will expire on $(chage -l $user | grep "Password expires" | cut -d: -f2 | tr -d ' ')"
            fi
        fi
    else
        account_status=$(passwd -S $user | awk '{print $2}')
        if [[ "$account_status" == "L" ]]; then
            echo "$(hostname -I | awk '{print $1}'), User $user: account locked!"
        fi
    fi
done
