The more common command to check mounted file systems on linux is the mount command which is used to not only list mounted devices, but also mount and unmount them as and when needed. Here is another nifty command called findmnt, that can be used to take a quick look at what is mount...
This tree starts with the on-CPU functions and works back through the ancestry. This approach is called a "callee based call graph". This can be flipped by using -G for an "inverted call graph", or by using the "caller" option to -g/--call-graph, instead of the "callee" default....
Heap Sort works by first transforming the list into a max heap – a binary tree where the parent node is always larger than its child nodes. The largest element (the root of the heap) is then swapped with the last element, effectively placing it in its correct position. The heap property...
Usually Hash Chain match finders are faster than Binary Tree match finders. The default depends on the preset: 0 uses hc3, 1-3 use hc4, and the rest use bt4. The following match finders are supported. The memory usage formulas below are rough approximations, which are closest to the ...
