Shell-init:error Retrieving current directory Solutions

Renamed a Web project, and then modified the Apache configuration to a new directory restart, the following error message appears:

Shell-init:error Retrieving current Directory:getcwd:cannot access parent directories:no such file or directory because the old directory has After the deletion, began to suspect that the Apache restart can not find the old directory error, checked on the Internet, this error is because the GETCWD command can not get the current execution of the working directory, may be because the directory has been deleted by other programs. For example: You first use a terminal into the directory/home/yangyz/test, and then open another terminal to delete the directory/home/yangyz/test, and then the first terminal to execute some commands or start some services will see the above error prompts.

The solution is to use the CD to enter any actual directory, and then execute the appropriate command.
