Vim: 'not usable computer' error trying to recover swapfile

Vim: Cannot Use Computer While Recovering Swap File

Vim is a highly popular and configurable text editor used by many developers around the world. One of the unique features of Vim is the swap file, which is used to save the current state of a file being edited. However, sometimes, Vim may display an error message stating that the computer is not usable while recovering the swap file. This article will cover the key concepts related to this error message, including what it means, why it occurs, and how to resolve it.

What is a Swap File in Vim?

In Vim, a swap file is a temporary file that stores the current state of a file being edited. The swap file is used to recover the file in case of a crash or power failure. By default, Vim creates a swap file for every file that is being edited. The swap file is named with the same name as the file being edited, but with a .swp extension. For example, if you are editing a file called myfile.txt, Vim will create a swap file called myfile.txt.swp.

Why Does the Error Message Appear?

The error message "Cannot use computer while recovering swap file" appears when Vim is trying to recover a swap file, but it cannot do so because the file is currently in use by another process. This can happen if you have another instance of Vim open that is editing the same file, or if another program is using the file. In some cases, the error message may also appear if the swap file has become corrupted or if there is a problem with the file system.

How to Resolve the Error Message

To resolve the error message, you need to identify the process that is using the file and close it. You can use the fuser command to identify the process ID (PID) of the process that is using the file. For example, if the swap file is called myfile.txt.swp, you can use the following command to identify the PID:

fuser myfile.txt.swp

This will display a list of PIDs that are using the file. You can then use the kill command to terminate the process. For example, if the PID is 1234, you can use the following command to terminate the process:

kill 1234

Once you have terminated the process, you can try recovering the swap file again. If the swap file is corrupted or if there is a problem with the file system, you may need to restore the file from a backup or recreate it.

The error message "Cannot use computer while recovering swap file" in Vim can be frustrating, but it is relatively easy to resolve. By identifying the process that is using the file and terminating it, you can recover the swap file and continue editing your file. It is important to ensure that you do not have multiple instances of Vim open that are editing the same file, and to regularly back up your files to prevent data loss.
