KSH Shell脚本无法压缩文件

Question

我有一个Korn Shell脚本，应该可以压缩文件，并且在开发中无法正常工作。相同的脚本可以在生产中使用，这很奇怪。我们最近在开发环境中将Solaris Unix盒升级为Linux盒。因此，我假设这可能是脚本无法执行的原因。

下面的图片显示了文件列表。用户将为要下载的文件选中一个复选框，然后单击“压缩并下载”链接，它应该将那些选定的文件压缩并保存到您的桌面。不幸的是，zip文件夹是空的。任何想法可能是什么问题？

这是下面压缩文件的代码。知道为什么这个Korn Shell脚本可以在开发中工作而不能在生产中工作吗？

# Utility to zip up files in the configuration_aerodynamic_properties area.
# Script takes two arguments the directory and the file list.
# The file list is tab seperated.
# This script returns the zip file.

@meuh我从-中删除了set -A FILE_LIST -，这是来自我们服务器的错误日志的结果。这是什么意思，因为我选择压缩并下载到桌面的txt文件仍未保存到zip文件夹中。以下是结果：
