# Linux – Bash hangs in Linux subsystem in Windows 10

windows 10windows-subsystem-for-linux

In Windows 10, I am using Linux subsystem. I first open a cmd terminal with administrator, and then start bash in the cmd terminal, and then use the bash shell.

Sometimes my bash hangs upon running in a terminal.

For example, when a file is opened by some software in Windows, I try to rename the parent directory of the file by mv fileParentDir fileParentDirnew in bash, and then bash will hang.
If I force to close the bash terminal, and then reopen a new cmd terminal to start bash again, the command bash will hang too. The problem can be solved by restarting Windows.

is there a solution to the hang problem, not by restarting Windows?

I googled and some said that multiple partition files might be the reason. But I am only using one single partition and partition file.

Thanks.

This is a known issue, and apparently, you must restart the computer to recover:
