In windowx running cygwin trip bash-3.02 $ (bash-2.05b $) and other similar problem solutions:

In Windows 3.02 64-bit system, when cygwin is used to run the liunux program, the following error occurs: Bash-$:

The reason is:

In the 64-bit operating system, the 32 program and the 64-bit program read the location registry key, in the 64-bit Registry Editor, HKEY_LOCAL_MACHINE \ SOFTWARE corresponds to the registry key of the 64-bit program, and the 32-bit registry key is mapped to HKEY_LOCAL_MACHINE \ SOFTWARE \ wow6432node. If both versions are required to take effect, you must modify the table items in both versions.
