推荐答案

脚本可能是使用＃！/ bin / sh期望/ bin / bash的行为。尝试执行脚本：/ bin / bash shell_script.sh

the script is probably using '#!/bin/sh' but expects the behaviour of /bin/bash. Try executing the script as: /bin/bash shell_script.sh

调试工具包括使用-x选项执行脚本，即bash -x shell_script.sh。从开始的问题看起来像一个未设置的变量，正在检查使用不受保护的形式：

debugging tools include executing the script with the -x option, i.e. bash -x shell_script.sh. The problem from the outset looks like an unset variable that is being checked using the unprotected form:

if [ $x = ]

问题是如果$ x未设置，那么你最终会得到一个空令牌，脚本失败。

the problem is that if $x is unset, then you end up with an empty token, which causes the script to fail.

对于未找到明确的clear命令，cygwin的实现是调用'tput clear' 'tput clear'，那么它应该工作。

for the explicit 'clear' command not found, the cygwin implementation of that is to call 'tput clear' if you replace the 'clear' call with 'tput clear' then it should work.
