fuser:tldr:12ff7

The command "fuser --verbose ${filename_or_directory}" is used to display the processes that are currently accessing or using a specific file or directory in a Linux system.

Here's what each part of the command means:

• "fuser": This is the command itself. "fuser" stands for "file user" and is used to identify the processes using a file or directory.

• "--verbose": This is an option that makes the command output more detailed and informative. It provides additional information about the processes using the specified file or directory.

• "${filename_or_directory}": This is a placeholder that represents the name of the file or directory you want to check. You need to replace "${filename_or_directory}" with the actual name or path of the file or directory you want to examine.

When you run this command with the appropriate file or directory parameter, the output will display a list of process IDs (PIDs), usernames, and other details of the processes that are currently accessing or using the specified file or directory. The verbose option provides more detailed information about these processes, such as command names, user IDs, and file descriptors.
