bash - 从文本文件批量创建账户

Question

我有以下脚本，它从 users.txt 中读取第一和第二个字段并使用它们生成用户名和密码并为每一行创建帐户。问题是脚本只为前两行创建帐户，而不是为其余的创建帐户

#!/bin/bash
FILE=/home/knoppix/users.txt
USERSH=/bin/bash


while IFS=":" read GECOS USRGRP ; do

groupadd -f $USRGRP



USERNM="u$(cat /dev/urandom| tr -dc '0-9' | fold -w 6| head -n 1)"
USERPW=$(cat /dev/urandom| tr -dc 'a-zA-Z0-9' | fold -w 6| head -n 1)


useradd $USERNM -p $USERPW -g $USRGRP -c "$GECOS,$USRGRP" -d $HOME/$USERNM -s $USERSH -m

ACCNT=$(grep $USRNM /etc/passwd)
echo "${tgrn}Account creation successful!${tr}"
echo "$ACCNT"
echo "Credentials"
echo "${tred}Username:${tr} $USERNM ${tred}Password:${tr} $USERPW"
echo
done < $FILE
