This article will explain in detail about the use of linux's grpck command to verify the integrity of the file. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Use the grpck command to check whether the data is stored correctly, whether each record contains enough information, whether there is a unique group name, whether it contains the correct user, whether the administrator of the group is correctly set, and so on. After the grpck check finds an error, the user is prompted on the command line whether to delete the wrong record. If the user does not explicitly answer to delete the record, grpck terminates the operation.

Syntax format: grpck [parameters]

Common parameters:
