bash - Regular expression in case statement

Question

I am trying to filter out some strings using case statement.

case $HOST in     
          Linux|Windows|Storage*)

I want to filter out the hosts which have names like this

1. test_prd_linux
2. test_prd_windows

How can i include *prd* in the above case statment? Something like this?

case $HOST in  
       Linux|Windows|Storage|*prd*)

Answer 1

这些是 glob，而不是正则表达式。

是的，glob*prd*将匹配您作为示例的案例（尽管*_prd_*如果这些示例具有代表性，我会使用更具体的模式）。

但是，您也更改Storage*为Storage，因此这将不再匹配它曾经匹配的某些字符串。也许把球星放回去。

case $HOST in
    Linux|Windows|Storage*|*_prd_*)
