导读:在以下脚本中,我收到一个错误: syntax error: unexpected end of file 这个错误是怎么回事?它正在指向该函数被调用的行. #!/bin/shexpected_diskusage="264"expected_dbconn="25"expected_httpdconn="20"expected_cpuusage="95"#expected_fd="100"httpdcon

当您的结构不匹配时,通常会出现此错误 – 也就是说,您没有匹配的双引号,匹配的单引号,没有关闭一个控件结构,例如缺少一个if的fi,或者一个缺少一个用于.
发现这些错误的最佳方法是使用正确的缩进,这将显示您的控制结构的破坏以及语法高亮,这将显示引号不匹配的位置. 在这种特殊情况下,我可以看到你错过了一个fi.在你的代码的后半部分,你有5个ifs和4个fis.但是,您还有一些其他问题 – 您的反引号触摸/tmp/alert.txt …命令在语法上无效,并且在if测试的结束括号之前需要一个空格. 清理您的代码,错误开始脱颖而出. (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
