Question

这是我必须从文本文件创建用户帐户的代码。用户名来自文本文件，我想将密码设置为unix lab。但是，这个脚本似乎不起作用。

#!/bin/sh
for i in `cat unix_tuesday.txt`
password = "unixlab"
do
echo "adduser  $i"
adduser $i 
echo -e "$password" | passwd $password

done

Answer 1

有几个问题：

您的for循环被破坏（do被错误放置）
passwd需要stdin input

这应该按照您的要求执行：

#!/usr/bin/env bash
for i in $(cat unix_tuesday.txt); do
   password=unixlab
   adduser $i 
   echo $password | passwd $i --stdin
done

另请注意adduser和useradd之间有difference。

通过ShellCheck报告执行此操作：

Line 2:
for i in `cat unix_tuesday.txt`
^-- SC1073: Couldn't parse this for loop. Fix to allow more checks.

Line 3:
password = "unixlab"
^-- SC1058: Expected 'do'.
^-- SC1072: Expected 'do'. Fix any mentioned problems and try again.

password作业位于for和do之间。将其移至开头会产生一组新的错误：

Line 2:
password = "unixlab"
         ^-- SC1068: Don't put spaces around the = in assignments.

Line 3:
for i in `cat unix_tuesday.txt`
         ^-- SC2013: To read lines rather than words, pipe/redirect to a 'while read' loop.
         ^-- SC2006: Use $(..) instead of legacy `..`.

Line 6:
adduser $i
        ^-- SC2086: Double quote to prevent globbing and word splitting.

Line 7:
echo -e "$password" | passwd $password
     ^-- SC2039: In POSIX sh, echo flags are undefined.
