By default, <code>top<\/code> sorts processes by CPU usage, but you can sort by memory usage by pressing the <code>M<\/code> key.<\/p>\n<p><code>htop<\/code> is an alternative to <code>top<\/code> that provides a more user-friendly interface and additional features. You can sort processes by memory usage by pressing the <code>F6<\/code> key and selecting the <code>MEM%<\/code> option.<\/p>\n<p>Both <code>top<\/code> and <code>htop<\/code> display the total amount of virtual memory available and used in the system, so you can easily see which processes are consuming the most memory.<\/p>\n<p>Another tool that can help you identify processes that are consuming large amounts of virtual memory is <code>smem<\/code>, which provides a summary of memory usage by process and by user. To install <code>smem<\/code>, you can use the package manager for your Linux distribution.
