sysctl:tldr:d80b0

The command "sysctl fs.file-max" is used to view or modify the maximum number of file handles that can be opened by the system.

In Linux systems, file handles are used to access files and other resources. Each open file or resource is assigned a file handle. The "fs.file-max" parameter represents the system-wide limit on the number of file handles that can be opened simultaneously.

When you execute the command "sysctl fs.file-max" without any arguments, it displays the current value of "fs.file-max". This value indicates the maximum number of file handles allowed on the system.

If you want to modify this value, you can use the "sysctl -w" option followed by the parameter name and the desired value. For example, "sysctl -w fs.file-max=100000" sets the maximum number of file handles to 100,000. However, please note that modifying this value requires administrative privileges.
