![]() ![]() Running the lsof command on a Linux filesystem will produce the following result, which shows the owner and process details for any processes utilising the file. To find out who is utilising any files on a file system, use the lsof command. That's true in many ways, therefore a tool that identifies open files is actually rather helpful. It's a frequent misconception that everything in Linux is a file. The lsof command stands for "list open files," but it can serve other purposes as well. You might need to use extra options, such as those in the example below, to view certain files. Output none of the processes are using scripts.txtĪgain, I've encountered instances, where some deleted processes continue to lock files until their parent process or an application connected to that process, has finished running. To reverify whether the process has been killed or not, we will again lookout for the “scripts.txt” file, $ fuser -v scripts.txt The -k flag in the fuser command can also be used to stop or kill processes from running on particular ports. Run fuser with the -v option, $ fuser -v scripts.txt To generate additional output so the user can see what fuser is doing, use the verbose option. Additionally, it offers details on the sort of access and the user who is in charge of operating that process.įuser can also be used in verbose mode by using the -v option. fuser commandĪ Linux command called fuser can be used to determine which process is using a specific file, directory, or socket. These commands collect information from the Linux kernel since it manages programs and file systems, among other things. There are a few commands that can assist us in locating processes that work with files, so we'll start there. Note − Linux commands are case-sensitive. The process that uses a file will be identified in this tutorial. Sometimes, when this occurs, we'll want to figure out which process is using the file. This indicates that a process is active on the system that is using the file and keeping it open for reading or writing. The potential error that you could experience is "the file is busy", or we may occasionally see the notice "the file is busy" when attempting to access a file. ![]() This is typically seen while mounting a share. There may be a situation where, despite the fact that no one is attempting to access the share to your knowledge, you are unable to unmount it.
